https://devzone.nordicsemi.com/f/nordic-q-a/16883/need-help-with-nrf52-ota-testerHello, I&#39;m trying the ota tester with pca10040 board however the ota tester won&#39;t run. System hangs around softdevice_enable() and goes to app_error_fault_handler. Both SDKv12.0 and SDK v12.1 won&#39;t run. The tester in SDK11 will run howeveren-USTelligent Community 13Fri, 07 Oct 2016 09:13:21 GMThttps://devzone.nordicsemi.com/thread/64673?ContentTypeID=1Fri, 07 Oct 2016 09:13:21 GMT137ad170-7792-4731-bb38-c0d22fbe4515:90d4804d-14ad-47ec-99f8-04ed6a696844Petter Myhre<p>Works fine here. What version of the S212 SoftDevice are you using? You should be using v2.0.0. What error does sd_softdevice_enable() return?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/64671?ContentTypeID=1Thu, 06 Oct 2016 12:56:04 GMT137ad170-7792-4731-bb38-c0d22fbe4515:347b3b10-e70e-4ac4-895b-dcad370ac646ola<p>thanks for the reply, I&#39;m trying the ota tester under the ANT DFU example. All i&#39;m doing is follow the instruction to try out the OTA. I believe that program will hang at sd_softdevice_enable and I didn&#39;t see any error code being returned. Thanks</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/64672?ContentTypeID=1Thu, 06 Oct 2016 07:09:22 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c58a75d5-d23f-4614-b0d4-fe6e5599dfb4FormerMember<p>Could could you please elaborate a little more? Which example do you use? What do you try/want to do? Which function returns the error code, making the application go to the error handler? Which error code does that function return?</p><div style="clear:both;"></div>
