Hi,
I was updating the parameters on my BMS and it got stuck at 50%. I waited for about 5 min, but it seemed stuck so I exited the app and restarted it. I now receive "get device info fail, please retry : -2" as an error message when trying to connect to the BMS in the app from Overkill Solar.

I've tried unplugging the bluetooth on the BMS, and unplugging the BMS, and reinstalling the app, but I keep getting the same error. Any ideas?

Also is it possible to reset the BMS somehow?

Thank you for your help.
 
Are you using Android? Did you try to reboot the phone?
 
Yes android and I tried rebooting it. I randomly keep receiving this error, can't figure out why.

I have the same issue ever since the beginning. I randomly cannot connect and the app gives me that error. I have to retry several times and fiddle with the refresh to connect about 10% of the time.

Did you find a fix?
