Hi ,everybody . when I usr QGroundcontrol set up the radio ，it reminds me that 1config error for RC. channel ,RC calibration check failed ,RC ERR: RC_3_TRIM>MAX(1500) ,detected 0 radio channels, to operate px4 , you need at least 5 channels . my Crazyflie phone app connecting to the board via Bluetooth is normal . what is problem with me?
when I update my firmware , and not select Airframe , the radio setup can calculate.
