1 week ago Hello? Could you please check the function declaration esp_err_t i2c_master_transmit(i2c_master_dev_handle_t i2c_dev, const uint8_t *write_buffer, size_t write_size, int xfer_timeout_ms); and find why?

Thank you.I had used the method in correct way before.But it still didn't work normally.The message from ESP32-S3 is actually the following text .Now the problem has been handled, because I have found that the GPIO which connect IIC devices are wrong.
