I am working with a pixracer and a Qbrain 4x25A ESC. I tried doing the ESC calibration through QGroundControl but got the message “calibration failed timeout waiting for bat”. I measured the voltage across the battery pack and it seems ok.
I haven’t configured the RC because I don’t have the receiver yet. Should I configure first the RC? Or should I be able to do the ESC calibration right now?
Thanks in advance and apologies for opening two threads in such a short timeframe.
I have the same problem: the ESC’s calibrate fine when I connect them to a CC3D flight controller, but the Pixracer + ACSP4 power board result in the “calibration timeout waiting for bat” error. Using QGroundcontrol 3.0, flashed the pixracer with standard, beta and master firmwares, same result.
When i am calibrating ESC in Qgroundcontrol, I am getting error in Octo cox airframe "calibration failed timeout waiting for bat”,
My Qgroundcontrol version is v3.2 and Firmware is 1.7.
Hey guys. This has happened with my grouup as well with our Pixhawk, and it was a silly thing but if you are just powering the Pixhawk through USB instead of through the power port on it with the Power Module that comes with the Pixhawk, it will give you this issue. So the “waiting for bat” is referring to power coming into the power port of the Pixhawk. I suppose then if you are doing this and still facing issues, then perhaps you start at testing out the port and such before moving on to trying other firmware or different ESCs or debugging your PDB (like we did).
Hi, here’s my order of doing things (doesn’t work and causes problems):
Click “calibrate” button in power tab.
Connect power module to battery.
Connect pixhawk (2.4.8) to power module.
Still throws the error.
I’ve tried manually calibrating the ESCs but then there are delays between each motors spinning when armed.
