How to send data of UART and SPI to one sample code

[Kaito]

Hi!!

I am now using SDK 14.0.0. and I have added UART functionality to the SPI program().

I could confirmed that SPI and UART can transmit data separately.

However, if I run both SPI and UART in one program, I cant see any output by teraterm.

I am now pursuing this cause, but if I initialize the UART of the main statement in debugging and then execute the SPI initialization process(APP_UART_FIFO_INIT), it will enter the error function(void app_error_fault_handler).

Do you know how to solve this problem??

best regards!!

Hi.

There shouldn't be any problem using UART and SPI at the same time, since they do not share the same instance ID.

I suggest you take a look at the tutorial: An introduction to error handling in nRF5 projects.

This tutorial explains how you can locate where in the code the app error handler triggered.
