Hi!

I wan’t to test out using the Here4 as an autopilot for a rover.

Everything was going smoothly, following the guide online until “Step2” [https://docs.cubepilot.org/user-guides/here-4/here-4-manual#step2-updating-to-here4-fc-firmware](https://docs.cubepilot.org/user-guides/here-4/here-4-manual#step2-updating-to-here4-fc-firmware)

I get as far as:

- Search parameter `FLASH_BOOTLOADER` , set the parameter to 1

- Then click `Refresh Params`, check if the parameter auto resetted to 0, confirming successful update.

The parameter auto resets - great!

I unplug the Here4 from the CubeOrange, open it and connect the full “connector 1” cable that was included to the break-out board and connect it to my serial to USB converter, but it does not show up on the “Install firmware” page in mission planner. The Here4 has lights on, in rainbow disco mode…

Anyone had succes using the Here4 as a flight-controller?

Hello, maybe you have connected the TX and RX to check

There is no true detailed guide on how to do and which exact version of FW one should use. I asked plenty of times and so far no reply
