You’ll want to update both your controller and the hub
Controller
To update the controller you can use @dennisglowacki script but with the updated firmware file from. Releases · openppg/eppg-controller · GitHub
Assuming you’re on Windows and don’t want to install the Arduino IDE here’s a script that you can run to update the controller to the latest version which I just made:
Batch5ControllerFirmware.zip (3.5 MB)
Just plug in the controller via the microUSB port at the bottom.
The new default is for 7S and you’ll be able to see the raw battery voltage anyways coming from the ESCs.
Hub
While the controller update above is still backwards compatible with the old hub firmware, to get altitude and temperature sensing here’s how to update the hub:
Simply download the HUB.bin file from this link https://github.com/openppg/eppg-hub/releases/download/v1.1/HUB.bin
Drag that onto a microSD card and insert it into the hub. Power up the hub and wait for about 30 seconds. The hub should now be updated. You can verify this by checking to see if the HUB.bin file is still on the microSD card. If it’s been deleted then you know for sure the hub was updated successfully.
Thats it. You should be ready to fly with latests and greatest firmware for both PCBs!
