DALY BMS problem - TimeoutError: timeout awaiting result 93, got 0/1 responses

[WolwX]

Hello,

Impossible to get my DalyBMS working. I followed the troubleshoot steps without success.

I use Batmon with another BMS, a JBD one, and that's ok since last update, but with the DALY one, impossible to get any information since long ago.

My DALY BMS is ok in the Android App, data are ok, so I unlink it to be able to appair with Batmon, it appear on the bluetooth scan, but for some reason, impossible to work.

Daly BMS 4S 12v Serial SH39F003 Software version 210629
