Hi.
In the past I built some software to communicate with chinese and european BMS with their Bluetooth Interface.
For example:
- energusps.com - Modbus over Bluetooth with raspberry.
- xiaoxiang - BLE (first with Raspberry, then with ESP32).
- ANT-BMS - Bluetooth socket (rfcomm like) with ESP32.
I always used the vendor's tools and reverse engineered some things, or use hints from elswhere.
With these data it was easy to capture data from the batteries for long term analysis (aging and defect cell finding).
Influx, Grafana ......
But now I am a little bit frustrated. I got a BMS from daly (the red ones) with a UART-Bluetooth dongle.
It works a bit like ANT BMS with BLE and traditional Bluetooth (sends two MAC's).
But daly is not able to send a APK/tool/software, because the customer needs WeChat (Chinese WhatsApp I think).
And as "not chinese citizen" it's nearly impossible to activate it.
So with no software, I cannot sniffer what commands are needed to read some values out of the daly BMS.
Is here someone having the software for this BMS, or has someone already found out some commands:
