Indoor ROCK Pi Hotspot Troubleshooting

If you are having trouble with setting up your hotspot or you have got a query, the following tips may help.

  • How to access the diagnostics
  • No lights are turning on
  • The device is not booting/Green activity light is off
  • The Green LED is blinking rapidly within a few seconds interval
  • A hotspot is not showing in the Helium App
  • A hotspot is not detecting Wi-Fi networks
  • Updating Nebra Hotspot Firmware
  • Syncing Issues
  • The onboarding key is missing an error
  • Hotspot not witnessing
  • Still having trouble

On the Nebra Helium Hotspots, we have two local diagnostics tools that can help you to find any issues with your miners. Please take a look at the dedicated local diagnostics page for more information: https://github.com/NebraLtd/Helium-Guides/blob/main/docs/handy-guides/local- diagnostics.md No lights are turning on You should see the lower light (Amber light) on the side of the unit turn on as soon as power is applied. If this is the case, ensure the power supply is firmly plugged into the wall outlet, the power jack is plugged into the unit and the wall outlet is switched on. To Do

  • The power adapter is connected correctly
  • Try a different power adaptor if available (12V 2.5A USB-C Power Adapter)

Upon power-up the lower LED (yellow) should light up instantly. Approximately after a minute, the top LED (green) should then start blinking. Green activity light is off The Green light is the acivity light and it should turn on solid in normal operation. Approximately after a minute, the top LED (green) should then start blinking. If not, contact customer support with hotspot details. © 2022 Passion Radio / NEBRA – www.passion-radio.com

The Green LED is blinking rapidly with few seconds interval The upper light on the back of the unit blinks rapidly with a few seconds interval. This is expected behaviour. If this is the case, use your web browser to access the diagnostic page of the hotspot. If the diagnostic page does not show any error, everything is fine. Hotspot is not showing in the Helium App It can sometimes take 1-3 minute from turning the power on for the Hotspot to show in the App. To Do

  • Wait for the hotspot to boot up before pairing (Wait 5 minutes)
  • Re-scanning a few times can then find the hotspot.
  • Ensure Bluetooth is turned on as this is how the application communicates with your Hotspot.

Please note: You will need to grant location permissions for the Application to access Bluetooth services correctly. Hotspot is not detecting Wi-Fi networks You may find that sometimes your Wi-Fi network will not show in the application if the signal is poor where the Hotspot is located. Please note, Nebra Indoor hotspot only support 2.4G Wifi network. To Do

Updating Nebra Hotspot Firmware
If after completing the initial troubleshooting steps above, you are still having issues, you may find your issues can be resolved by ensuring it is running the latest up-to-date software.
Nebra Hotspots automatically update once connected to the internet, if you are using an Ethernet connection leaving the hotspot for around half an hour should ensure all updates are downloaded.
If you are having difficulties connecting your Hotspot to Wi-Fi, then it would be recommended to move it to a location where you can plug it into an Ethernet connection for half an hour to let it perform updates. Then move it back to the normal location and re-try setup.
Syncing Issues
The Helium Syncing Process sometimes takes some time. Some customers report that the hotspot takes multiple days to sync properly. This is not so much an issue with Nebra, rather an issue with the Helium blockchain itself. Please allow the hotspot to take some time, especially during the 90% mark. If you are still having trouble, feel free to contact support below. If you are not familiar with Nebra’s diagnostics page, we highly recommend connecting to your hotspot directly using the local IP address in combination with a web browser. This will provide more insight between the device, and the Helium blockchain.

Please note, Nebra will provide an instant sync feature that download a new snapshot on startup and If you ever find your hotspot more than 300 blocks behind according to the local IP diagnostics you should reboot the hotspot. Onboarding key is missing error Please contact our tech support via sales@nebra.com and provide your MAC address. We will update the onboarding key for you. Hotspot not witnessing Hotspot will not get witness with various reasons from device loation to device relayed. To Do

What is the antenna connector on the Hotspot?
The indoor unit has a RP-SMA Female Connector on.
Can I add 4G connectivity to my Indoor Hotspot?
No, the indoor unit does not have the ability to have a 4G Modem added, you could use a solution like a MiFi or 4G to Ethernet module to achieve the same result.
How much internet data per month does the Hotspot use?
Currently we are roughly estimating 30-50GB per month.
The actual usage may be slightly less or more and will be something we up-date over time as we start measuring more units. Once all hotspots become “light hotspots” this data usage will reduce.
What antenna is included with the Hotspot?
A 3dBi Omni-directional antenna is included with the Nebra Indoor Hotspot, specifications can be found in this manual Upgraded antennas can be purchased separately from our website: https://www.passion-radio.com/hnt-antennas/196
Can I use PoE with the Indoor Hotspot?
If you wish to use PoE with the Indoor Hotspot you will require an active PoE splitter that outputs 12V to the unit. Alternatively you can use passive PoE adapters as long as the power provided to the unit is between 9 and 16 Volts and can provide 15W of power.
How long does it take for my Hotspot to sync with the network?
This can vary depending on your internet connection speed. However, in our testing it takes approximately 24-48 hours for the initial synchronization to be completed. © 2022 Passion Radio / NEBRA – www.passion- radio.com
