    Hi Dinesh,

    1.    To program the BQ25703A IC, you need to configure the registers using I2C. The BQ25703A has its unique I2C address, and the host can can configure the charger to operate.
    2. The .bqz file available in BQSTUDIO can be used with EV2400 to configure the part. The user guide shows the steps to configure the EVM, and configure registers according to your system requirements. Configuring the registers over I2C through BQSTUDIO is similar to how BQ25703A would be configured by host in a system, so this is the sample code.
    3. I am not familiar with ESP32, but as long as it has an available I2C bus through which you can configure the BQ25703A IC then you should be fine.
