KW45: Peripheral Uart Over BLE

Rathore-pioneer — Mon, 26 May 2025 10:51:42 GMT

I am using an NXP kw45 EVK board. trying to configure BLE as a peripheral role where I can see received data over UART/SPI interface.

Using an example from SDK 24.12.00 wireless_uart_freertos.

This is working fine with IOT-toolbox mobile app.
I am trying to make this sample app compatible with NRF connect mobile app.
but when I made some modification to replicate same as Nordic UART service (NUS) it is not connecting with NRF connect app.

for modification I just changed the service and char UUID's as given below.

UUID128(uuid_service_wireless_uart, 0x9E, 0xCA, 0xDC, 0x24, 0x0E, 0xE5, 0xA9, 0xE0, 0x93, 0xF3, 0xA3, 0xB5, 0x01, 0x00, 0x40, 0x6E)

UUID128(uuid_uart_stream, 0x9E, 0xCA, 0xDC, 0x24, 0x0E, 0xE5, 0xA9, 0xE0, 0x93, 0xF3, 0xA3, 0xB5, 0x02, 0x00, 0x40, 0x6E)

UUID128(uuid_uart_stream_tx, 0x9E, 0xCA, 0xDC, 0x24, 0x0E, 0xE5, 0xA9, 0xE0, 0x93, 0xF3, 0xA3, 0xB5, 0x03, 0x00, 0x40, 0x6E)

here is an expmale of NUS which I am trying to replicate with kw45.
#sdk-nrf/samples/bluetooth/peripheral_uart at v2.9.1 · nrfconnect/sdk-nrf · GitHub

Please suggest if I am missing anything to replicate the peripheral_uart example.
Am I using correct example from the SDK or should I use anything else.

Hello,

Hope you are doing well. We don’t support third parties' applications.

As you might know, Wireless UART is a custom profile. If you want to create your own profile, I recommend checking this community post: KW38 Custom Profile - NXP Community

Best Regards,

Ricardo
