I am building a new quadcopter but pixhawk fails to arm. Here is what I have done till now
1. Connected radio and esc to pixhawk.
2. connected a independent bec to output rails for power. Didn't connect pixhawk power module because I don't have the right connection with me.
3. calibrated radio in QGroundControl. All good.
4. tried to calibrate ESC by recommended all in one method. No response from pixhawk. I guess it never goes into ESC calibration mode.
5 Gave up on all in one calibration, by passed pixhawk and connected servos directly to reciever's channel 3. Did calibration one by one using this method.
6 reconnection reciever and servos to pixhawk again.
No response to throttle. Tried disable switch nothing. blue led will keep flashing. If I do a long press of disable switch, its led goes into quick flashing.
Does any of it sound familiar. I am out of options.
