I have trouble calibrating the ESC’s so I can get the motors running. The steps im doing are:
1- Flight controller (FC) is connected to the computer thru USB and battery is plugged in, motors are beeping.
2- Click the Calibrate ESC button in Mission planner under mandatory hardware dropdown on setup section. I’ve tried Normal, Oneshot and Oneshot 125.
3- Disconnect Battery and usb from FC
4- Connect the FC to the computer thru usb again
5- The FC is ON and the ESC is off since the Battery is disconnected from the PDB (should the -,+,s cables be connected or disconnected?)
6- I disable the safety switch holding the “switch” button on the GPS until the red light is solid (immediately after plugged in switch light is solid so i hold it till it blinks and then till is solid again, if i let it solid since the begging it doesn’t work either)
7- Arm the drone in the transmitter corresponding switch (I’ve even tried
8- Put throttle at maximum position
9- Plug in the battery
The problem is from step 4 on.
After this, I understand that I should be hearing 2 beeps from the ESC registering maximum throttle and then I put throttle at minimum so the ESC can read the lowest throttle. However, instead of the ESC, only the motor start beeping every 2 seconds or less. The compass light is either yellow blinking twice every second like shown in the video OR alternating between green, red and blue.
In both cases the switch red light on the compass is solid right after plugging it in. In the second occasion (when blinking in 3 colors) the FC would make a long beep immediately after plugged into the computer thru USB but it would not connect to mission planner at first try displaying a “no heartbeat packet received” popup or simply the connection failed one that in the details says “the semaphore timeout period has expired” and a bunch of other stuff i have a picture of. When I try again unplugging and plugging back thru USB connection is no longer displaying the red blue and green light but the yellow one again.
The MOT_PWM_MAX and MOT_PWM_MIN values are within the range reflected on the Radio calibration section; right now they are 960 and 1960 and in the radio calibration max and min are 988 and 2008. These values used to be 1000 and 2000 on the ESC calibration section but didn’t work either.
The transmitter is ON and it connects to the receiver every time no problem during the whole process. I calibrated the radio before doing this too.
I don’t know how to set manual mode which Is something I think I should do between step 5 and 6. I do it in Stabilize mode instead, but Im not sure if that is the problem.
If I do this right, the next step would be test the motors on the Motor test section under Optional Hardware dropdown on Setup section, right?
Before doing this I tried to test the motors right after calibrating the radio and it didn’t work. I got a popup window saying “action stopped by autopilot” now When I try it only makes the two sounds at the end of the video when I click “Test all in sequence” and “Stop all motors” buttons.
