app_error_fault_handler() when using spi_master_using_nrf_spi_mngr example

[FrB]

Hello,

I'm beginner with Nordic nRF52 devices.

I'm working on a PCA10040 (2.1.0) dev kit and I would like to communicate through TWI interface.

Then I have installed SES and opened the example given in \nRF5_SDK_17.0.0_9d13099\examples\peripheral\spi_master_using_nrf_spi_mngr.

I have NO mbed Application Shield daughter card connected on the dev kit, I would like first to test the FW example before adding my custom board with sensor on it.

When I debug this project, I come in app_error_fault_handler() after the call of nrf_twi_mngr_perform() (in main.c)

I don't expect to raise an error handler if TWI sensor is not responsive, right?

Why do I have this error handler?

Thanks,

François

Hi François

The example is set up to treat any error returned from the twi_manager module as a critical error, by calling the default error handler. 

If you want to test the example without a sensor attached I would suggest changing this behavior, and rather print the error code that is returned to the log so that you can see if the twi_manager library returns an error or not. 

Then the code will continue running, and you can try to connect your shield and (hopefully) see the error disappear. 

Best regards
