https://devzone.nordicsemi.com/f/nordic-q-a/1505/adding-new-timers-to-ble-proximity-sample-appI&#39;m trying to add another timer to the BLE proximity app sample code in a new source file which is a driver for a GSM modem. My timer handler function is never called. In main(), right after the existing timers_init() function, I call gsm_init() inen-USTelligent Community 13Tue, 04 Feb 2014 12:45:40 GMThttps://devzone.nordicsemi.com/thread/6691?ContentTypeID=1Tue, 04 Feb 2014 12:45:40 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e319a0ec-78f0-41c8-b2a4-b3e476046dbbEliot Stock<p>This was of course entirely my fault. My call to gsm_init() was happening <em>before</em> ble_stack_init() in main(), so in fact the soft device hadn&#39;t been enabled at all at that point. Working just fine now.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/6690?ContentTypeID=1Mon, 03 Feb 2014 17:08:56 GMT137ad170-7792-4731-bb38-c0d22fbe4515:dcefb863-bb93-4ae3-921b-7effc3e6d507Eliot Stock<p>Yeah, pretty sure the softdevice is being enabled, though I&#39;ll check that again. Thanks. Will open a case with the full code once I&#39;ve had another look.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/6689?ContentTypeID=1Mon, 03 Feb 2014 10:59:25 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9ea31f37-834c-4f17-90da-fab83268f4a3Ole Morten<p>I also can&#39;t quite see why this shouldn&#39;t work, but I&#39;d be interested in seeing your complete project. If you can&#39;t give your complete code here, feel free to create a regular support case for it.</p> <p>The only thing I can think of is that the app_timer module doesn&#39;t start the LFCLK by itself, so if you don&#39;t enable the softdevice, no callbacks will be called. However, it doesn&#39;t sound as if that&#39;s the problem here, since things work when you have the code in main.c.</p><div style="clear:both;"></div>
