Hello,
with my ENERGY BMS, I think this is a DALY BMS does not work as a known protocol: e.g. [DD A5 05 00 FF FB 77]
After installing [Sinowealth BMS Tool Setup V0.2.msi], I could read and administer everything with the PC.
When scanning the first battery cell, a very simple protocol emerges:
0x0A -> I think start
0x01 -> battery cell 1
0x02 -> I think 2 bytes are being sent
The following is received:
0x0D, 0x3D -> 3389 mV o.k.!
0x47 -> CRC? but how is it calculated
In any case, the CRC is also calculated from the bytes sent
Last weekend I tried to solve the problem with the help of the Internet, without any result.
Is there any indication of how the CRC is calculated, I've tried about 20 exotic CRC calculations without results.
