MMR not responding
A few months back I ordered an MMR for my graduation project. It used to work great, but after not touching it for a few weeks it didn't respond to anything. Mbientlab told me that the battery was broken, so I replaced it.
Now the problem is that the sensor works, but only when plugged into a power source. When I try to make a connection with it, either by phone or by pc, it doesn't work unless I plug it into a powersource.
Does anyone know what the problem is?
