For E-bike battery i use BQ2060. This BMS communicate state off charge to a display Three wire SMBus. As the BQ2060 is outdated i have now BMS with BQ78350. I can communicate with the board with EV2300. My problem is our display does not show up SOC. Is there any difference between SMBus from bq2060 and Smbus from BQ78350. We cannot change the display!

Those are two different devices. Some commands and behaviour will be different. Pls review the TRM and user guide of the bq78350
thanks

Thanks Onyx, yes we use the BQ78350R-1 And these are two different devices i understand, for that reason they have both different numbers. As far as i know the BQ2060 is out off production and followed up by BQ78350R-1. So the design with the BQ78350-R1 is ready but it does not show up the SOC on our SMBus display. Do you know how to solve the problem?
