Hello sir,

as you said 'You can send the device ID command and see if you get the correct response from it. The gauge will respond on it's address when it gets an smbus command.'But i dont know how to do it.Can you tell me the syntax format for sending a command to gauge and where i can check response? I am very new to this programming and getting very tough to me but eagerly want to know.

Controller is STM32L476RC and gauge is BQ40Z50R2.

Thanks

Mohan.
