After I flashed to Copter 3.6.1, BATT2_VOLT_PIN and BATT2_CURR_PIN disappear in MP Configuration page, except BATT2_MONITOR which is still there. Any body has clue ?
Current monitoring has been a problem for most people. Couple of years back, I have no problem with current sensing on Arducopter and Arduplane.
I think the solution is to set BATT2_MONITOR = 4 and press “Refresh Params” button and the rest of the parameters will appear.
The issue is that AP is hiding some parameters because we have so many now that if we show them all, users will complain that after connecting with a ground station the parameter download is really slow.
