https://devzone.nordicsemi.com/f/nordic-q-a/38444/nrf52840-range-at-commands-and-mesh-capabilityHi, 1. I need to know the bluetooth 5 range of the nrf52840 dongles which I need to use on custom boards. 2. Can I use AT commands to communicate with the dongle over uart and if so where can I get an example. 3. Can I use the mesh functionalityen-USTelligent Community 13Wed, 12 Sep 2018 11:43:56 GMThttps://devzone.nordicsemi.com/thread/148391?ContentTypeID=1Wed, 12 Sep 2018 11:43:56 GMT137ad170-7792-4731-bb38-c0d22fbe4515:041a3069-aa3f-4817-b078-2e5edd299265MartinBL<p>Hi,</p> <ol> <li>We haven&#39;t tested the range of the nRF52840 dongle. The range depends on so many variables that you will need to test it yourself to get a reliable result.&nbsp;Please refer to this blog post for more info regarding BLE 5, nRF52840, and range:&nbsp;<a href="https://blog.nordicsemi.com/getconnected/tested-by-nordic-bluetooth-long-range">Tested by Nordic: Bluetooth Long Range</a>.&nbsp;</li> <li>Unfortunately we don&#39;t have any examples or solutions for AT commands, but it is certainly possible to implement. This is probably the best place to start:&nbsp;<a title="UART/Serial Port Emulation over BLE" href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.2.0/ble_sdk_app_nus_eval.html?cp=4_0_0_4_1_2_24">UART/Serial Port Emulation over BLE</a>.</li> <li>There is <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk/keydef/PLUGINS_ROOT/com.nordic.infocenter.meshsdk.v2.2.0/index.html?cp=4_1_0">no official support for the PCA10059 in the Mesh SDK</a> yet. However, you <em>can</em> run mesh applications on the dongle, but you will have to make some changes in the code to reassign pin numbers used for buttons and LEDs, etc. Furthermore&nbsp;you cannot debug your code with the dongle alone. For that you will need a DK board or some sort of debugger.</li> </ol><div style="clear:both;"></div>
