Hello. I connected the FMB204 tracker to the charger. The tracker battery is also connected.
Sent an SMS command "login pass battery", received a response:
BatState: 1 FSMState: ACTIVE ChargerIC: OFF ExtV: 12412 BatV: 3944 BatI: 8
This means that the battery is not currently being charged. I turned off the power of the tracker, there was 1800mah battery power left.
After ~40min, the tracker turned off, so the battery was discharged.
I connected the power to the tracker again, after a while I typed the "login pass battery" command, I received a response:
BatState: 1 FSMState: ACTIVE ChargerIC: OFF ExtV: 12429 BatV: 4015 BatI: 8
I turned off the power again, the battery sat down after ~ 20 minutes.
I can not understand why it is not charging when the power is connected to the tracker via the red and black wires. The battery capacity should allow the tracker to be kept without power for a day, but for me it runs out in an hour already.
Please help me understand the problem. This is my first tracker.
