Hello,
I'm trying to change some parameters on the BQ-27421-G1A but I'm always have an error.
I want to change Battery capacity, TCA parameters (clear set), FCC parameters, SOC1 parameters, SOCF parameters, design capacity, design energy.
I tried the command in the technical documentation chapter "Data Memory Parameter Update Example".
I also tried to send the command in the dffs file.
The problem is with the checksum. The module doesn't answer. I have an error each time.
I don't understand why.
What is the way to change parameters.
Can you help me?
Can you please tell me which command I have to send? At which baudrate (I'm usign 400kHz and I tried 128kHz).
Regards
Guillaume
