Flashing your Helium Hotspot
Step 1 - First, you will need to remove the current microSD card inserted into your SenseCap miner. You will need to follow the instructions from SenseCap to see how to do this. You can follow https://docs.sensecapmx.com/home/sensecap-gateways/sensecap-m1/m1-troubleshooting/micro-sd-card-errors/flash-new-micro-sd-card-image
Step 2 - Insert the microSD card either into an SD adaptor or if your memory card reader takes microSD directly, then insert that and connect it to your computer or laptop.
Step 3 - On your computer, download and install Balena Etcher from - https://www.balena.io/etcher/
Once downloaded, open up the balenaEtcher program on your computer or laptop.
Step 4 - Before we move to the next step, you will need to download the latest OpenFleet software for your Hotspot, which you can find here - https://hub.nebra.com/
Click on the link "SenseCAP" on the left hand side menu.
Click on the latest file to download the Firmware.
Step 5 - Click on the Flash from File button in balenaEtcher and navigate to where you save your downloaded Firmware file. Select it to be installed.
In the middle button of balenaEtcher, click select target to select your SD card to install the OS (It may be selected automatically).
Finally, click on the Flash! button to begin installing the Firmware to your microSD card (you may need to type your login password here).
Step 6 - Once it has finished, you can now remove the SD card from its adaptor and card reader and then insert it back into the SenseCap hotspot.
Step 7 - Finally, connect your Ethernet cable to the hotspot and the power cable. The hotspot should now boot up with your new Firmware installed. It may take up to 30 minutes to do all the updates.
It would be best if you use Ethernet for the first initial boot of the hotspot
If you are onboarding your SenseCap with our Nebra Dashboard then you can find the serial number and MAC address needed to onboard on there verse side of the Hotspot.
