https://devzone.nordicsemi.com/f/nordic-q-a/68797/samsung-galaxy-a-series-is-not-able-to-connect-uart-with-nrf5340-boardHello. Currently, the Samsung Galaxy A series has a problem that UART communication is not available. I want to find the cause and solution of this problem, How can I find it? Thank you.

If you don&#39;t have access to an Ellisys or Frontline sniffer, then you can use the Nordic nRF Sniffer tool:<br /><a href="https://www.nordicsemi.com/Software-and-tools/Development-Tools/nRF-Sniffer-for-Bluetooth-LE">https://www.nordicsemi.com/Software-and-tools/Development-Tools/nRF-Sniffer-for-Bluetooth-LE</a><br /><a href="https://infocenter.nordicsemi.com/topic/ug_sniffer_ble/UG/sniffer_ble/intro.html">https://infocenter.nordicsemi.com/topic/ug_sniffer_ble/UG/sniffer_ble/intro.html</a></p> <p>Please also try some of the other BLE examples for comparison, e.g.:<br /><a href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.0.2/examples_ble_peripheral.html">https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.0.2/examples_ble_peripheral.html</a></p> <p>For instance you can try BLE Blinky application, Heart Rate application and HID keyboard application for comparison.</p> <p>Best regards,<br />Kenneth</p><div style="clear:both;"></div>
