Hello,
I have a BQ769142 connected to a MCU by I2C. First, I could read direct values (cell voltages, die temperature,...) without any problem. However, when I want to write to the device, I noticed that I can't even write to direct command addresses (like alarm enable). For more convenient test, I disconnected the BMS chip from MCU, and connect it to microchip I2C-USB converter. As you see in the below picture, I can read stack voltage value, almost read alarm-enable default setting value. But when I want to write, it gives error. How can I write to this direct value? I tested many other ways, but no one worked.
Thank you
