Hi Jorgen !

Thanks a lot for this tips.

After fighting days on that, i can conclude you are 100% right:

!!!!!!!!! if you use TWIM, JUST ROMOVE ALL THE TWI STUFF FROM YOUR SDK_CONFIG.H !!!!!!!!!!!!

Otherwise you will get headhack and white hair before the end of the day. I started from twi_example, try to keep the sdk_config.h used etc.... But at the end, ( at least for nrf52833) TWi is depracated according to the documentation and also all the functions like nrf_driver tx or rx are depracated and docuementation advice to use nrfx_twim_xfer function.

Hi,

I agree that it sounds like a priority issue.

Are you using the nrfx_twim API directly in your application, or do you use the legacy nrf_drv_twi API? Note that NRFX_TWIM_DEFAULT_CONFIG_IRQ_PRIORITY will be redefined in apply_old_config.h to the value of TWI_DEFAULT_CONFIG_IRQ_PRIORITY if TWI_ENABLED is defined in your sdk_config.h file, regardless if TWI_ENABLED is set to 1 or 0. If you are using nrfx APIs, you need to completely remove the legacy configs from your sdk_config.h file to get the NRFX configs working correctly.

Best regards,
Jørgen
