ble_peripheral/ble_uart_app not working on custom nrf52382 board

parvathi

Hi All,

I am using a custom board with nrf52832 and BMI160 sensor. I also have nrf52382 DK evaluation kit. This sensor was programmed with heart rate and battery service by the vendor.

I successfully programmed ble_uart_app on nrf52382 DK evaluation kit and see the response on nrf uart 2.0 app. But the same code does not work on my custom board i.e, the custom board shows up as Nordic_UART_service but gets disconnected  says "Device doesnt support UART" . Does it have to do with my UART configuration? Also, the heart rate and battery service are still advertised, how is that possible?

What should be the connection of the rx and tx pin of nrf52 on my custom board board ? On nrf52 DK the rx and tx pin is connected with the MCU. Kindly, let me know your thoughts.

IDE :  segger embedded studio

Thanks

    Hi,

    The pins that are used are P0.08 and P0.06, RXD and TXD respectively.

    Hi,

    I am using same pins for rx and tx. They are not connected in my custom board. I am using ble_peripheral_uart exampleBut I am getting " Device does not support UART . Disconnected. when I use UART 2.0 App. Please let me know what could be the issues.

    Hi,

    If you use the same project then you either have to connect the pins or switch which pins that are used for the UART in the example code.
