Unable to connect after uploading firmware

Hi, there.
My 3DR radio telemetry was working fine until I press the button “Upload Firmware(Local)” in 3DR radio setup in Mission Planner. The transmitter (the one connected to the computer) flashes green LED light all the time while the remote (on the copter) gives solid green light. I am still able to load setting in MP, but I can’t connect it anymore. There is a timeout and “no heartbeat packets received” is shown.

I have tried reset to default, reinstall the driver and switch to other computer. It is all the same result.
Very appreciate if anyone can help me


I seem to be having a similar issue , did you get this resolved?
