Yeah, I just started having the same problem. I don't know what the fix is...
Do you have the controller on when executing the initial procedures?Have you tried to factory reset? With power off, start by holding power and fly. If that does not work I found the following instructions under all green lights on copter:
"You'll need to execute these instructions many times until it works; Unfortunately, it also could fail and prove the autopilot needs to be replaced.
Please, perform the following:
1- Remove the gimbal and take a look at the accessory bay; You'll see the SSWT button
2- Press and hold the SSWT button.
3- Turn on the Solo while you are pressing and holding the SSWT button
4- Release the button until the Solo stops beeping
5- Reboot the Solo and the controller if nothing appears to change"
Not sure if this is your problem.Refer to the instruction manual when all else fails.
I had just gone through this scenario. If you have the Tower app. You might want to change the value in one of the parameters to "0".Aye, your drone won't start if the battery is reading 0%, although I think you should be getting an alert on the screen saying "battery too low for flight", so the 0% without that message is a bit odd. Like DaveB said, check the battery pins and wires in case something is loose. You can also press and hold the power button on the battery while plugging it into the charger.
Use Mission Planner or Tower to change SYSID_SW_MREV to a value of 0
