I have followed the documentation to setup a telemetry radio however it will not function. In windows, when I click “load settings” I get “failed to enter command mode” error (disconnected state/correct baud rate are set). I booted into linux mint and tried in mission planner there and got "error during system.TimeoutException: The operation has timed out [a lot more error text]
Admittedly this was a knockoff radio from ebay as all genuine models (holybro etc) seem sold out in my country atm. Has anyone got any advice from similar struggles?
