Hi

when i call twi_master_transfer function in for(;;) loop of file ble_app_hrs project.

Kindly tell me what to do for that.

for (;;) { for(i=0;i<10;i++) {

            twi_master_transfer(addw, dataW, 2, 1);
	delay();
	twi_master_transfer(addr, dataR, 20,1);
        dataW[0]=dataW[0]+20;
         err_code = ble_hrs_heart_rate_measurement_send(&m_hrs, dataR);
		}
            if (
                (err_code != NRF_SUCCESS)
                    &&
    (err_code != NRF_ERROR_INVALID_STATE)
    &&
    (err_code != BLE_ERROR_NO_TX_BUFFERS)
    &&
    (err_code != BLE_ERROR_GATTS_SYS_ATTR_MISSING)
)
{
    APP_ERROR_HANDLER(err_code);
}
		 
		
    // Switch to a low power state until an event is available for the application
		err_code = sd_app_event_wait();
  APP_ERROR_CHECK(err_code);
}

}
