Bobcat OTA Update

Sometimes Explorer is not working, don’t keep trying the explorer page because it will make things worse. Use your Disgnoser or Hotspot Utility App to get the latest status in your miner. Any other tools will have a latency.

My hotspot shows RED light

Use Bobcat Diagnoser to see the Miner status in your hotspot.

RED light means your Miner isn’t started. Miner is a docker process in your Bobcat machine. If it has been less than 5 minutes, it’s OK because maybe it was caused by a restart after an OTA update. If it lasts several hours, maybe it got stuck during the OTA, you can try to restart it. If the light is still RED, you need to contact your hotspot maker to get support. See Why Offline / Syncing.

My hotspot shows YELLOW light

Use Bobcat Diagnoser to see the Network status in your hotspot.

YELLOW light means that Miner has been started but it can’t connected to the Internet. If it’s only been several minutes, it can be caused by OTA update, Network disconnection or some other network issues. For network issues, please see Network.

If it’s been several hours, it could be stuck on a block when syncing. In this case, pay attention to the Helium update announcement, maybe the new snapshot update will help. If it’s not working, try restarting your Miner or waiting for an OTA update from your hotspot maker. It may also cause Offline status in Helium App. See Why Offline / Syncing.

My hotspot shows WHITE light

The Firmware is being automatically updated. This can take several minutes and will go back to Green once it completes.

My hotspot shows BLUE light

BLUE light means the bluetooth is in match mode. You can connect to Bluetooth and do a diagnosis. If it doesn’t disappear, restart the Miner.

My hotspot shows CYAN light

Investigating. The only information found: . It was said that the bluetooth is still in Pair mode but some miners entered CYAN color directly right after miner restarted. It should be a state between YELLOW and GREEN. It works but not 100%.

My hotspot is RELAYED
The Helium App / Web Page shows “Offline

The status on Helium App / Web Page depends on the latest data received from the Helium Network. It has a delay. If your Miner’s light is green, you can just wait, the status will change to “syncing/synced” later. It’s possible that it shows offline but it’s syncing when you sync it for the first time, due to some Router / State Channel issues. Please see Why Offline / Syncing.

My Helium App shows “Needs Attention

The “Needs Attention” warning is basically “Relay”/”Offline”/”Not Syncing”/”Syncing”. But it’s a delayed status. You can use Helium Hotspot Utility App to diagnose it to get latest status of your Miner.

For Bobcat, you can also use the Web Diagnoser.

Use Bobcat Diagnoser to see the Temperature & Network in your hotspot.

A sample report:

My miner has been worked but back to syncing/offline again

Use Bobcat Diagnoser to see the Temperature & Network in your hotspot.

There are several possibilities.

1. Your network has an issue

Take a look at the light of your Miner. If it’s RED, restart the Miner. If it’s YELLOW, test the WiFi it’s using. If it’s connecting to a Cable, connect the Cable to another device to test the Internet. If internet is OK, restart the Miner and wait until it’s back to GREEN. All these operations should be after you reserved your miner’s IP address.

The issue can also be a laggy WiFi connection.

Some have low latency, some have high.

  "DownloadSpeed": "5 Mbit/s",
  "UploadSpeed": "9 Mbit/s",
  "Latency": "24.621771ms"

  "DownloadSpeed": "55 Mbit/s",
  "UploadSpeed": "20 Mbit/s",
  "Latency": "85.234333ms"
2. The Helium Router / State Channel has big delay

Too many hotspots are joining everyday. The Helium API servers kept scaling out but sometimes it can’t catch up the speed of hotspots adding speed. In this case, it’s possible the API shows laggy height and wrong status.

Router and State Channel details:

3. Blockchain goes too fast

This often happens after a chain halt. The fastest speed of producing blocks is 50 seconds. The expected block time is 60 seconds. After a chain halt, the blockchain will try to run as it’s fastest speed when possible to produce blocks. In this case, some miners may not able to catch up the speed. But the blockchain will finally back to 60s so your hotspot will also back to synced.

4. You Miner Temperature is too high

The Bobcat Miner has been tested in 60 celsius for 13 days but it not recommanded to put your Miner in hot environment. If it’s too hot, network, CPU and LoRa performance maybe affected which can also cause bad performance.

My Helium App shows an old Firmware version

Use Bobcat Diagnoser to get the newest Firmware version in your hotspot.

Sometimes OTA can take up to 24 hours. If the firmware version still shows old version after OTA finished, there are two possiblities.

Helium App issue

If it’s an old version, uninstall Helium App and install the newest versoin. If it’s the newest version, force exit and re-enter the Helium App. If it doesn’t work, reboot your hotspot and run diagnostics.

OTA failure

If OTA failed due to network issues, reboot your Hotspot, wait for several minutes and try again. If it’s the same result, try to contact your miner maker.

The explorer shows Synced, but the App shows Syncing

There is an issue with the App constantly showing syncing, but the explorer is more accurate according to the Helium web page.

Can an Offline/Syncing Hotspot Beacon/Witness?

NO. Only Synced hotspots can do beacon / witness. The API / explorer is slightly behind. Sometimes you can see a Syncing hotspot beaconing / witnessing, but it is actually fully synced. For acurate status, only by using the app diagnostics for a hotspot you own. Otherwise everything is sort of laggy.

The Bluetooth button doesn’t work

Restart your miner and try again. Sometimes it has latency.

You can also Use Bobcat Diagnoser to diagnose your Bobcatminer.

I can’t find / found old my Bobcat via Bluetooth

Restart your miner and wait for several minutes. When the light changed to YELLOW or GREEN, try pair mode again.

If you have multiple Bobcats, it always find the first one, try to switch your phone’s Bluetooth off and on between pairings.

My Power Adapter is broken

Contact your hotspot maker to get a new one or buy 1 if you don’t want to wait. For Bobcat, you can buy a replacement on Amazon. The type is 12V 1A. Sample:

I got Onboarding Error when adding a new Miner

These errors may include:

You already own this Hotspot.

I guess you are very RICH because you are adding many Miners in a row 😆 . It’s a good thing but the App is not as stable as you think 🙁 . After you finished adding the first Miner, the bluetooth is still enabled and you started to add the second one. Maybe the App will show you the first one which you’ve already added. Acutually you are trying to add the first one again. You can power off the first one after it was added OR wait for several minutes before adding the second one.

Unable to find Hotspot in the Onboarding Server.

I guess you are a Helium Network Pioneer or the hotspot miner support team was trying their best to process your order in a very high priority. In this case, maybe your Miner wasn’t from the factory product line directly. It’s from a special channel to give fastest delivery. But in that case, some onboarding MISS may happen because it’s a manual work. Bascially you need to contact your Miner support team and tell them your Mac Address, they can fix this issue.

Hotspot miner is waiting to start. Please try again in a few minutes.

After your Miner connected to the internet, it will try to get the latest update and install it. Keep it online and wait until the light becomes green. Then maye you will see the light switches between RED and GREEN several times which the Miner is restarting by itself. If you are trying to add your miner during the restarting , you will get this error.

Unable to Add Hotspot for reason: {invalid, gateway_already_active}

This is a blockchain transaction error. You Miner won’t be add to the blockchain right way. The CG/Validator need to approve the transaction which needs some time. If the Miner has already been added, you will see this error in the transaction log.

Device xxxx-xxx-xxxxx-xxxxxxxxxxx was disconnected.

This is because the Miner isn’t started. You can wait for several minutes to try again. If it’s not working after several times, maybe you need support from your Hotspot maker.

How can I open a Bobcat?

There are 4 screws in the back of the box. You can lift the cover after 4 screws removed. (Nothing else need to be removed, try hard, it’s a little bit tight.)

What’s the Bobcat Antenna Connector Type?

Bobcat & Rak is using RP SMA Female Connector (1).

You need a RP SMA Male adapter to connect to it.

You may also need to choose N type connector to connect to your Non-stock Antenna.

Why does my Beacon have NO WITNESSES?

There are several possibilities.

1. No other hotspots in your Antenna’s coverage.

If there are only several Miners in your area, it’s possible they don’t talk with each other depending on their Antenna types. For example, in the image below, there are only 3 miners in this area. Hotspot 3 is Offline, maybe Hotspot 2 is using a Panel Antenna which only talks to futher Hotspots. In this case, Hotspot 1 will be of NO WITNESSES.

2. Your Antenna is broken.

In this case, your miner also has NO WITNESSES. See Bobcat Antenna Repair

Look at the image below, I have a hotspot worked well but it suddenly stopped beacon and witness after 5:19pm. In this case, I can still see “Packets Transferred”, but it’s not from Antenna, it’s for some contribution to the transaction operations. In the next several days, I totally lost all witnesses and all beacons were 0. I went to the roof, and noticed the Antenna cable connecting to Bobcat totally disconnected maybe caused by the wind.

3. Your Network has a very strict Firewall.

If your Network has a very strict firewall, your Miner won’t be able to sent out a witness receipt. Understanding Witnesses and Relayed Hotspots

Relay maybe caused by strict Firewall but not all the Relays. Some relayed hotspots can also sent out receipt but with low efficiency.

Peer book shows a normal hotspot listen to tcp 44158. Now you know why port 44158 is so important.
Relayed hotspot listening to a p2p-circuit address .
Some hotspots showing Relay in the Helium App but acturally it has two listen addresses. It can send out receipt. 😀
4. Maybe your Network is too slow.

I have seen some hotspots only have several kb/s speed. In this case, it can’t catch up the speed of blockchain and the activities will become strange. Some hotspots have a good download and upload speed in the test but with very big latency. The latency can be caused by your Router, ISP, etc. You can search for what can cause latency.

Why doesn’t my Miner have a Beacon?

Use Bobcat Diagnoser to diagnose your Bobcatminer.

Sometimes it’s not your side, it’s the Blockchain.

Several steps to finish a transaction, it’s complex.

If your beacons looks like the image below, that means your Miner tried PoC but failed. Basically in this case, your miner should be relayed or behind a strict firewall.

If you have had Beacons before but it disappeared recently although you still have a lot of Witnesses, it may caused by the Network Firewall even you opened port 44158. It is possible that your hotspot starts to send out beacons again after restarting / reseting your ISP modem / router, or rebooting your router.

If it disappears again after rebooting/reseting, it may caused by Packet Filter Rules which filters the packets from/to your Miner. Try to add pass rules or disable deny rules to make packets pass. See Network.

It’s also possible that your ISP company banned traffic from/to your Miner from their side. In this case, you need to change your IP address but that’s not easy. Also some routers have port forwarding issues can also cause this problem.

If your Miner has good network settings but didn’t sent out a Beacon from the beginning, maybe your Antenna / Pigtail is broken. See Bobcat Antenna Repair.

Your hotspot is not sending out beacons but you still have a lot of Witnesses. It is very hot and it has been connected by too many Miners. Basically in this case, I think you can give up, your witness income will be Good Enough. 😀

Why my Miner has lot of PoC Challenges without Beacons?
If it’s less than several days, maybe you just need patience, gossip is super slow, come back and check again the next day. Or it can be caused by a lora_pkt_fwd issue. It’s being used to send Lora data. Restart your miner / contact your hotspot make to fix it.

Why the Discovery Mode doesn’t have Hotspot response?

Discovery Mode isn’t a real simulation of beacon and witness. Sometimes it won’t work as expected. It can help you do troubleshooting but don’t rely on it.

You can try Discovery Mode at night. There is little noise at night which may give you a good result. If the Disco Mode is working and you haven’t received any response, check points below.

1. Your network doesn’t allow incoming / outgoing connections.

Look into your router, open 44158, change packet rules, etc. Sometimes restarting your router / your Miner may fix it too. See Network.

2. Your Antenna is broken, your cable isn’t connected well orthe Antenna Signal is too weak.

Try to use a “Digital Multimeter” to test your Antenna Cable & Pigtail if you have one. See Antenna.

3. All the hotspots nearby are Offline / Syncing / Relayed / Weak Signal / Using Directional Antenna. 😆

Buy more Bobcats, then build your own Online / Synced / Non-Relayed / Strong Signal / 360°C Antenna miner network.

My Antenna Pigtail is broken, how can I change it?
Can I use the Bobcat stock 4dBi Antenna outdoor?

The stock bobcat antenna is outdoor rated & waterproof.

How should I choose an Antenna?

See Antenna.

How should I choose the Cable?

There is a calculator to calculate the loss. See Antenna. LMR400LMR600 cable has very little loss, but is much thicker and less flexible than RG58 or LMR240 cable, making it harder to work with. SNR too clear will also cause lower HNT, so it should be combination with your Antenna, the height of your Antenna and the Location.

My miner STUCKED at 910,391 or some block

If your miner added recently and it stucked at 910,391, it may caused by a snapshot issue which have already had a fix. You can try to restart your Miner to trigger an update.

If it’s not 910,391, it may caused by another issue: An Out of Memory error caused failure when loading newest snapshot (help your miner sync faster). The Miner uses about 200M meory when executing normal tasks. There was a sudden increase of memory usage when loading a big snapshot file which caused the crash. A new OTA has been released, keep your miner online can receive the newest OTA update. If it’s not working as expected, try to restart your Miner. If your Miner kept crashing (Green, Yellow and Red light kept switching in a circle) and it didn’t fix after restarting it, contact your hotspot maker.

There were some chain halt which caused many miners stopped syncing before. In this case, basically Helium had already posted announcements in both Web and App, of course Discord too.

My daily mining HNT is very low, how can I increase it?

Good Location / High Enough / Online / Synced / Non-Relay / Strong Signal / Good Network / Lucky. That’s it.

See Tuning Your Hotspot.

How should I take care of my Hotspot?

Take care of your Cash Cow!

Don’t put it in high humidity / temperature environment. To be continued.

I lost my Bluetooth Pin

Sorry I never use it. I always put Paperclips in my wallet. 😆

How can I transfer the Hotspot?

Please see detailed instruction:

The Hotspot must be fully synced with the location asserted, and have recent network activity for the transaction to succeed. Recent Activity is described as witness, beacon, or challenger activity in the past 1200 blocks.

195 replies on “Troubleshooting”

The LED of Bobcat is constantly switching between Red, Yellow and then Off, respectively for 5, 3 and 1 seconds. Anybody knows what this means? Herewith some additional info which might help troubleshooting:

– Miner hasn’t been mining yet, only syncing constantly since I received it 1 week ago, after I repositioning the lights started switching. For over 24 hours now;
– I can’t access Bluetooth function, as the LED keeps on switching between Red, Yellow and Off;
– Can’t access the Diagnoser as I can’t connect with the internet, both Wifi and Ethernet;
– Connecting an antenna doesn’t make any difference.

So I’m a bit lost here. Any help would be much appreciated! 🙂

I am sending beacons constantly but I am not witnessing other beacons at all since I Installed my antenna outdoors. its been several days. Discovery mode shows upto 150 hotspots sometimes. What could be the issue? Before the antenna change it was working fine….

I have the same identical situation. I upgraded from the bobcat stock antenna to a RAK 5.8dbi one. Previously I was witnessing a lot of beacons but not sending any beacon. Now I’m sending a lot of beacons but not witnessing any other beacons. Maybe it need a resync?

i had to reboot my hotspot when i did so it no longer lets me connect via bluetooth so i enter in my ip address into the search bar to go that route to diagnose it and now it has a new hotspot name in the ip diagnoser
my hotspot changed names what do i do?

how do i fix this i cant find anyone who knows what to do in dischord

It caused by the chain variables change. It will take sometime for the hotspots to adapt new changes. Basically it’s a global issue but I think it will come back in a week.

I bought a Bobcat Miner 300 and did set it up straight away. It synchronized for eight days (by that time the blockchain was at about 99%, then decreased to 98% overnight) and then the LED light went yellow (3 days offline and yellow light now).

Even in the Helium app I cannot connect with the hotspot via bluetooth to see the sync. status

I Need some help, please

Kind regards

how long does it take for them to push the update throught to your hotspot when filling out that form. i have another bobcat not in use and i almost wanna say f-it and unbox it and set it up. this one just will not communicate
would you?

Hello, Beaconer.

My device is synced with the latest OTA, it is connected to the internet, it is at a good height and everything is fine. But I have 3 weeks just doing “Sent Beacon” and “Challenged Beaconer” but I have not done “Witnessed Beacon” and I don’t know why. My device is seeing more than 45 devices in the list of witnesses in the last 5 days at the app but I am not making profit from witnesses. What’s going on? Can you help me? Thanks.

Maybe your router / modem has something wrong. Take a look at the network. Try to remove all the firewall and watch the diagnostic log see if something changes. Then add back your firewall settings to get to know which one is causing the issue.

Having the same issue! All was working fine… 3 days back and all is going wrong… router / modem all working fine

My 3rd party cable broke while miner was on. The N Female connector just popped off the cable. How do I know if my miner was damaged due to this? Both Outbound and Inbound Peer-to-Peer Connection says OK in Helium Hotspot Utility app and I do get witnesses. Is it safe to say that it wasn’t damaged? The reason why I ask is that the amount of activity has decreased but it might be due to something globally rather than my miner specifically..

Your hotspot looks good. It’s something global. If it’s a Bobcat, it’s hard to break it because it’s industry level mainboard which can works under AT mode without issues. But sometimes the blockchain part will have some issues if you power on/off too many times in a short period time. Basically connecting Antenna directly to your Bobcat won’t cause any issue. But for other miners, it depends on the hardware, you’d better power off your hotspot then change Antennas.

Why is Bobcat always going offline during the last 3 days? Nothing was changed from my side… internet always working…

I think you are talking about the Helium Explorer? Yes, it can have several days delay. You can use the diagnoser or hotspot utility to see the status of your hotspot.

So I recently had to replace my pigtail cable on my miner as it split. I properly connected it and rebooted my miner and it’s synced. However, I am still getting 0 witnesses. I find 143 hotspots in discovery mode and I don’t see any problems on the diagnoser.

My Bobcat is having zero witnesses for beacons sent(zero witnesses so far historically and zero when running discovery). Am able to witness and send out challenges.

Went through the steps and checked everything. Everything looks good with the one exception being the Helium API showing p2p in listen address. All other diagnostic indicates port 44158 and NAT type are correct and open without issues.

Only had the miner for about a week and the issue remains the same with both the stock antenna and the 8dbi Rak antenna. I’ve opened the Bobcat unit and the antenna cables appear to be attached. The I’m running a TP Link Deco M9 router. Any ideas what might be the cause of this issue?

The Antenna’s dbi and height are already set. Is there anything else that can be trigger the lack of witnesses? Another miner in the same zone has over 40 witnesses (my miner sees 40 nearby miners, but zero witnesses). Can the p2p exception be the issue and this being an overly aggressive firewall?

Hi was wondering what this means from
The diagnosis and how can I fix this ?


“pubkey”: “11BVUxRnYyKSV9Satvcww5J71zwoDQdcWE1SLqJEQiLAydDcGFo”,

I dont know what to do…..i followed every steps from here. My Bobcat is fully synced…ports are open…nat typ none. No more firewall….. The miner earns good…but every 2 or 3 days the sync status goes from green to white. And miner height “freezes” and dont get higher….every 2-3 days.

My internet speed is 50 Mbit down and 5 mbit up….23 ms latency.

Any ideas?

Sometimes your peers stucked, it will take sometime to catch up the blockchain.
It’s blockchain, anything is possible. Your hotspot is not alone. Be patient, if it not back for a long time, try a fastsync.

I just set up my bobcat two days ago. The light is blue on explorer it states that it still syncing however on the helium app on my
Phone in indicates that it “needs attention”. What should I do? Thanks for your help.

New miner, when I try to connect via bluetooth to register it the helium app shows :
Onboarding Error
Your onboarding address is invalid.
Please contact the Hotspot
manufacturer for next steps.

Hello Beaconer, I just ordered a new SD Card with firmware for the Rak V2. Some are saying to make a copy right away when I receive it, and others are saying put it in the Rak, sync it to 100%, then remove it and copy it. I’m confused 🙁

hi my miner to day is gone. i cant see my miner in wallet. i so try many thing i removed helium app and instal again but i dont have it o cant connect to my miner

If you’re seeing zero balance or no Hotspots in your app, please close and re-open the app or go to Settings and toggle the API provider. This re-establishes the connection to the API.
