undefined reference nrfx_twi_xfer

[Simon]

sdk 15.0, SES

In CMSIS checked NRFX_TWI_ENABLED, and checked and unchecked TWI_ENABLED to no avail.

Looked at driver API, but with no specific hint.

Looked for other TWI examples that might use nrfx twi, no other but SPIM.

Anything else?

Have you included nrfx_twi.c and nrfx_twim.c in your project?

[Simon]

strange, for the includes had to toggle (comment, uncomment) and now ok.

-thank-you.

That seemed to do the trick while still using legacy nrf_drv_twi.h, but with edits completed according to migration guide steps, and using only nrfx_twi.c and nrfx_twim.c, the undefined issue now seems to be persistent.

With the nrfx_twi_xfer line commented out, the rebuild is ok. Checked spelling as well.

Any other suggestions to try?
