https://devzone.nordicsemi.com/f/nordic-q-a/25968/spi-master-stops-working-after-s132-softdevice-enabledInitialization: The softdevice is initialized as in the BLE UART example. The body of the ble_stack_init() function is identical to the BLE UART example. SPI is initialized as in the SPI peripheral example, but I have gone over to writing the registersen-USTelligent Community 13Mon, 16 Oct 2017 12:18:34 GMThttps://devzone.nordicsemi.com/thread/102306?ContentTypeID=1Mon, 16 Oct 2017 12:18:34 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e3b1543a-5260-48ba-b2f1-c5283ce268d8Hans<p>Turns out it was me doing something stupid all along, I should have double checked this. I changed to another pin, and everything works as expected.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/102305?ContentTypeID=1Mon, 16 Oct 2017 11:07:24 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c8f53e6b-a83f-47a9-801c-f4f457cdbfa1J&#248;rgen Holmefjord<p>Have you tried using different pins? Note that by default, the BLE examples in the SDK use the LF crystal as source for the low frequency clock. The crystal is <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52832.ps.v1.1/pin.html?cp=2_1_0_3#pin_assign">connected to pins XL1/XL2</a>, which is shared with GPIO pins P0.00/P0.01 on the nRF52832 IC.</p><div style="clear:both;"></div>
