From one day to the next I lost the binding between the Commando 8 controller and the Starling. Everything was working fine with both the controller and the drone, but today I received the message "No SD card" in the RC controller , I try checking the SD card from the RC on a computer, but it wasn´t recognized, so I replaced the memory card and attempted to bind again, following this tutorial: https://docs.modalai.com/voxl-elrs/#binding-procedure . However, I don't have the 'ExpressLRS' option in the TOOLS menu of the RC controller. Do i need a specific file on the SD card? or What can I do to bind my radio to the Starling?
