[Vamshi]

Hii,

    I am currently trying to communicate with BQ4050 via SMBUS communication, I am using STMCUBEID  as development enviornment and I am using stm32 nucleo board and trying from past two days but i am unable figure out what is the issue so if anyone has the project related to can share me that could be useful to revive and know where i made the mistake and I am also uploading my project related to it you can guide me where i am doing the mistake. I am waiting for your reply.

Thank you

So what have you done so far to try to find out?

Do you have basic comms working? eg, can you read the Device Type and Version registers?

Have you used an oscilloscope on the SMBus lines to check voltage levels, clean edges, noise, etc?

Have you used an analyser on the SMBus lines to check that your comms are in accordance with the BQ4050 specifications ?
