[apdobaj]

can somebody tell me where to find these error codes? error = app_twi_perform(&m_app_twi, als31300_read_sensor_transfer, 2, NULL); APP_ERROR_CHECK(error); perform is returning code 0x00000011

So far I have been able to find error codes in one of the following files.

components/libraries/util/sdk_errors.h components/softdevice/s???/headers/nrf_error.h
