I recently assembled a 8s 280AH bank using batteries from Docan (thanks Jenny!). It came up easily and after manually top balancing the cells I ran a 250AH discharge cycle, all went swimmingly. After recharging the bank, I started having problems with the bluetooth connection. The blue light on the module went off and the app was unable to see/connect to it.
The first time it did this I disconnected B- for a while and reconnected it and all was well. But soon thereafter the blue light started going off and the app would not see/connect, and disconnecting the battery offered no remedy.
I contacted the seller of my BMS (Sriko batteries) and he said he would send a new bluetooth module. I got it today, and unfortunately it does the same thing as the old on. When you mate the connectors, the blue light comes on for about a second and then goes off. Whenever the blue light is off the bluetooth is apparently not working.
Any ideas? I'm starting to think it must have something to do with the BMS board but the BMS worked fine.
