About m_xfer_done

[Vijayneerukanti]

After nrf_drv_twi_tx() function and nrf_drv_twi_rx() function, m_xfer_done is checked using APP_ERROR_CHECK(m_xfer_done). What is the significance of checking m_xfer_done? What is the output we will get by checking the status of m_xfer_done?

Thanks

Hello,

m_xfer_done is checked using APP_ERROR_CHECK(m_xfer_done)

Where exactly do you see this check?
APP_ERROR_CHECKs should be used on all error codes returned by SDK driver function calls, such as the error code returned by nrf_drv_twi_rx, etc., and not on boolean (or any other) variables.

Best regards,
Karl
