Hi, I have an older FLARM in my glider and found some issues last weekend while flying. I'd like to update the firmware but I can't find any detailed guide to follow.
So far I have found this guide:
https://support.flarm.com/hc/en-us/a...-SD-card-slot-
Only issue I have is how to connect it. I have a serial to USB cable but the next requirement is "A cable connecting the RS-232 adapter with the FLARM device"
Does that mean I need a console cable (rs-232 to rj45) as well?
If anyone has some more details on how to connect it, would be greatly appreciated!
