Hello, I am using MBN52832DK development board which have nrf52832 on it. I am using ble_uart_app and I can communicate with my pc terminal through micro-usb. Now I want to communicate with anotheren-USTelligent Community 13Fri, 22 Jan 2021 13:20:29 GMThttps://devzone.nordicsemi.com/thread/290757?ContentTypeID=1Fri, 22 Jan 2021 13:20:29 GMT137ad170-7792-4731-bb38-c0d22fbe4515:258fbe34-26ce-4d1f-9844-c010b5c1bb40Simonr<p>Hi</p> <p>I&#39;m not familiar with this board, but configuring which GPIOs are used for UART communication in software should be pretty simple if you&#39;re using the ble_app_uart example from our SDK. Most of the pins on from the nRF52832 can be used, so by changing the pin configs in your project to I.E. the P0.15, P0.16, P0.17, and P0.25 should make these pins in charge of UART communication.</p> <p>Alternatively, in <a href="https://no.mouser.com/pdfdocs/Murata_MBN52832DK_UG.pdf">the MBN52832DK user guide</a>, it is stated that you can remove Resistors R39-R42 in order to disconnect the default UART pins from the USB-UART interface. I assume that this would redirect the pins to use P0.05-P0.08 pins on the board for UART instead.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
