hi, haakonsh.

I've been trying to add codes of SPI into ble_app_uart. Yet I came across some problems.

My question listed below: https://devzone.nordicsemi.com/f/nordic-q-a/30373/spi-nrf52832

Would you take a look about it? thx

Hi, haakonsh.

thx for your reply. I just get some insight about rewriting the nus_data_handler. Am I right?

Hey masloooo,
The UART, SPI and TWI peripherals share HW resources. This means that you cannot use UART0 and SPI0 at the same time. You can however use UART0 and SPI1.

I suggest you stick to ble_app_uart unless you want to go deep into BLE and create your own service and characteristics.
You can add the SPI driver to the ble_uart example and set up the driver configurations in main.c, then you need to create a command line interface to parse the UART strings into SPI driver function calls.

Cheers Håkon.
