nRF51822 BLE and SPI slavehttps://devzone.nordicsemi.com/f/nordic-q-a/28475/nrf51822-ble-and-spi-slaveHi, I am working with the BLE Nano module and the mbed online compiler. I have the Nano acting as an SPI slave. The problem occurs when I try to add BLE functionality. As soon as I add the ble.init() call to the code, SPI stops working and I receiveen-USTelligent Community 13Sat, 23 Dec 2017 16:32:22 GMTRE: nRF51822 BLE and SPI slavehttps://devzone.nordicsemi.com/thread/112593?ContentTypeID=1Sat, 23 Dec 2017 16:32:22 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bedcc83b-c9af-4541-b19e-a4d6c9713cd5Mikael L.<p>Hi Jørgen. Sorry for extremely late reply. I was using the latest version when I posted the question. I see now that there is an update. Will try that when I am back to work. The other difference is of course that I use the SPISlave class and not master.</p><div style="clear:both;"></div>RE: nRF51822 BLE and SPI slavehttps://devzone.nordicsemi.com/thread/112592?ContentTypeID=1Wed, 15 Nov 2017 14:22:28 GMT137ad170-7792-4731-bb38-c0d22fbe4515:94935ae7-d4ec-4fdd-ac12-0c613f8e1cdfJ&#248;rgen Holmefjord<p>I&#39;m not able to reproduce this issue using the code you posted above on a nRF51-DK (modified code to match my available pins, and removed code that created compile errors), together with the SPI master example from our SDK. Are you using the latest mbed libraries?</p><div style="clear:both;"></div>RE: nRF51822 BLE and SPI slavehttps://devzone.nordicsemi.com/thread/112591?ContentTypeID=1Tue, 07 Nov 2017 21:02:40 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7f921c70-1dbc-463f-9a5b-ff8d65217b64Mikael L.<p>Of course, I updated my post. I have some different replies for debugging. However, none of these ever get transmitted when i first initialize BLE.</p><div style="clear:both;"></div>RE: nRF51822 BLE and SPI slavehttps://devzone.nordicsemi.com/thread/112590?ContentTypeID=1Mon, 06 Nov 2017 11:34:41 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ff0c21d7-d52f-46ed-8624-5784ef7212a0J&#248;rgen Holmefjord<p>Could you post the code of <code>spiRunner()</code> function?</p><div style="clear:both;"></div>RE: nRF51822 BLE and SPI slavehttps://devzone.nordicsemi.com/thread/112589?ContentTypeID=1Thu, 02 Nov 2017 11:33:13 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6d219ba8-f029-4ef0-a8c4-3a4a93044193Mikael L.<p>Yes, as soon as I comment out &quot;ble.init()&quot; it works well again.</p><div style="clear:both;"></div>RE: nRF51822 BLE and SPI slavehttps://devzone.nordicsemi.com/thread/112588?ContentTypeID=1Wed, 01 Nov 2017 13:50:27 GMT137ad170-7792-4731-bb38-c0d22fbe4515:84477d77-fa62-42d8-a757-d5d2d4a53687J&#248;rgen Holmefjord<p>Do SPISlave stop working just from initializing the BLE class?</p><div style="clear:both;"></div>
