UART pass-through for communication between iOS app and controller boardhttps://devzone.nordicsemi.com/f/nordic-q-a/33176/uart-pass-through-for-communication-between-ios-app-and-controller-boardHi, My desire is to connect a BC832 module (with nRF52832 on it) to a UART on a controller board and then send data from an iOS app (programmed in Swift) through the BLE module to the controller board. I&#39;m not really in a position to write any firmwareen-USTelligent Community 13Mon, 09 Apr 2018 13:35:15 GMTRE: UART pass-through for communication between iOS app and controller boardhttps://devzone.nordicsemi.com/thread/127449?ContentTypeID=1Mon, 09 Apr 2018 13:35:15 GMT137ad170-7792-4731-bb38-c0d22fbe4515:630ce1cb-85c0-41f7-9e9c-a5ba3885d84cBj&#248;rn Kvaale<p>1) You can download the firmware from the <a href="https://www.nordicsemi.com/eng/nordic/Products/nRF5-SDK/nRF5-SDK-zip/59011" target="_blank" rel="noopener noreferrer">Nordic SDK download page</a> (use the latest SDK). <a href="https://devzone.nordicsemi.com/f/nordic-q-a/24933/nrf52832-bare-chip-programming" target="_blank" rel="noopener noreferrer">This link</a> might be useful for programming the FW onto the board. I don&#39;t think you will need the Fanstel evaluation board like <a href="http://www.fanstel.com/bt832-1/" target="_blank" rel="noopener noreferrer">described in this link</a>.</p> <p>2) There are multiple resources available for interfacing the nrf52832 from the iOS device. I would definitely download the nrf toolbox app from the app store, <a href="https://github.com/NordicSemiconductor/IOS-nRF-Toolbox" target="_blank" rel="noopener noreferrer">including the swift source code</a>. I would take a look at the UART app inside the nrf toolbox app. You can&nbsp;test this iOS app with the <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.0.0/ble_sdk_app_nus_eval.html?cp=4_0_0_4_1_2_24" target="_blank" rel="noopener noreferrer">nordic uart example</a> in the nordic sdk.</p> <p>3) Take a look at this documentation for setting up serialization (i.e. using the nrf52832 as BLE connectivity between the iPhone &amp; the controller board.</p> <p>Hope that helps!</p><div style="clear:both;"></div>
