https://devzone.nordicsemi.com/f/nordic-q-a/73777/the-program-hangs-while-executing-the-example-codeI am confirming ADC sampling 420Hz operation by following question. https://devzone.nordicsemi.com/f/nordic-q-a/69096/1khz-or-more-adc-sampling-rate-over-ble The source code is as follows. What mistake did I make?en-USTelligent Community 13Fri, 09 Apr 2021 07:45:01 GMThttps://devzone.nordicsemi.com/thread/303907?ContentTypeID=1Fri, 09 Apr 2021 07:45:01 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4183d116-223a-4ff5-b78f-4ddbd1033589Vidar Berg<p>Hello,</p> <p>This is actually as intendend in the original example. The sample application is configured to enter System OFF mode (i.e. deep sleep) from the&nbsp;BLE_ADV_EVT_IDLE event after the advertising has timed out. The only problem that is that the chip can&#39;t enter System OFF mode while it&#39;s in debug mode, and this is why the program ends up in the error handler if you let advertising time out while debugging.</p> <p>If you want, you can disable advertising timeout by setting APP_ADV_DURATION to &#39;0&#39; and replace the BLE_GAP_ADV_FLAGS_LE_ONLY_LIMITED_DISC_MODE flag in advertising_init() with &#39;BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE&#39;</p> <p></p> <p></p><div style="clear:both;"></div>
