https://devzone.nordicsemi.com/f/nordic-q-a/92506/how-to-send-data-continuously-with-nusDear Nordic fellows, I have a nRF52832 and I want to use Nordic UART Service to send data in peripheral mode. What is the proper way to use this service? . I&#39;m using nRF5_SDK17.1.0 The ble_app_uart example performs a do while loop with condition err_codeen-USTelligent Community 13Mon, 03 Oct 2022 13:33:57 GMThttps://devzone.nordicsemi.com/thread/389011?ContentTypeID=1Mon, 03 Oct 2022 13:33:57 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1c24f2b8-e448-42a9-9d62-6999e2d3729aHieu<p>Hello Fernando,</p> [quote user=""]What I&#39;m trying to do is call the ble_nus_data_send() function and if I get an <span style="color:rgba(0, 0, 128, 1);">NRF_ERROR_RESOURCES</span> error, I save the data_array in a FIFO buffer.<br />When the <span style="color:rgba(0, 0, 128, 1);">BLE_GATTS_EVT_HVN_TX_COMPLETE</span> event is received, I retrieve the data from the FIFO and call the ble_nus_data_send() function again.[/quote] <p>I believe this direction is completely fine. Are you having some trouble with it?</p> <p>I also don&#39;t see any immediate problem with your initial approach and code. What is wrong with that one?</p> <p>My hands are a little full right now, but if there is a chance I&nbsp;will also&nbsp;try to cook up an experiment with the code you provided to see what is wrong.&nbsp;</p> <p>Best regards,</p> <p>Hieu</p><div style="clear:both;"></div>
