Do I need to order a new BMS and BT dongle or might there be a way to fix this?

Monitoring individual cell voltages (Smart BMS, Balance charger)

I just wired up my LLT smart BMS and I am having the exact same issue - all seems well, but it won’t read any data from the BT module. I did not short anything to my knowledge. Tried disconnecting the BT module, reinstalling the app, etc. [image] Also, I noticed it makes a high pitched noice when it’s connected. I assume that’s normal? Edit: This is on iOS app, 12s, all cell voltages at 3.69V
