https://devzone.nordicsemi.com/f/nordic-q-a/28167/connect-via-external-mcuHey, I am using WT51822-S4AT module and want the nrf51822 to connect to phone. I don&#39;t have nrf51-dk. I am using stm32f0-discovery kit. Can it be done using that kit? I searched for examples but coudn&#39;t find anything.en-USTelligent Community 13Fri, 15 Dec 2017 14:43:28 GMThttps://devzone.nordicsemi.com/thread/111252?ContentTypeID=1Fri, 15 Dec 2017 14:43:28 GMT137ad170-7792-4731-bb38-c0d22fbe4515:708ef229-9cf6-445e-9aed-05eee761f82aSigurd<p>Hi,</p> <p>This module comes pre-programmed with SoftDevice + interface-application. You can control the module from the stm32 using UART AT-commands. You need to find a UART example for the STM32, and configure it to send to send AT commands as described in chapter 6 and 7 here: <a href="http://www.wireless-tag.com/upload/file/p1aq90sft54vp98i89r44cng53.pdf">www.wireless-tag.com/.../p1aq90sft54vp98i89r44cng53.pdf</a></p> <p>Have you considered buying a nRF51 or <a href="https://www.nordicsemi.com/eng/Products/Bluetooth-low-energy/nRF52-DK">nRF52-DK</a> instead ?</p><div style="clear:both;"></div>
