TWI_Scanner example on PCA10040 not Working

[Ameer Usman]

The TWI_Scanner example is building and downloading fine (using SES) but it just prints:

"TWI scanner started."

Then nothing in terms of scanning addresses etc.

It does not give any app error checks. Seems it gets stuck inside:

err_code = nrf_drv_twi_rx(&m_twi, address, &sample_data, sizeof(sample_data));

Let me know if further information is needed.

Found the problem and was on my end. Actually another device was connected on the same pins of I2C that was not using I2C communication (I guess it was using SPI). Removing that device fixed the problem.
