https://devzone.nordicsemi.com/f/nordic-q-a/8495/beacon-problem-with-ledHello, I&#39;m using exeprimental dual mode example with my Beacon kit. I ported the example to work with pca2006, but i&#39;m having problems with led. On my mkit, leds work just fine. But on beacons, when i define a led as output, led starts shining.

Dunno how, but it started working with the same conditions as before. Strange... Thanks for your help.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/31003?ContentTypeID=1Mon, 03 Aug 2015 16:15:59 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a777688c-491c-4ec0-abc3-e308212af2f9Susheel Nuguru<p>Yes, all LEDS are active low, that means that they glow when you set the pin low. As soon as you configure them as output, then they are not open and the default value is zero which is low. This will light the LED up</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/31002?ContentTypeID=1Mon, 03 Aug 2015 16:13:09 GMT137ad170-7792-4731-bb38-c0d22fbe4515:150d5a36-8259-4ed3-933a-371fd97c2d71Susheel Nuguru<p>There is only the hard way. I see that you tagged KEIL in your question, so do CTRL+SHIFT+F and search for the pin numbers for the leds through out your project and go through them painfully : (</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/31001?ContentTypeID=1Mon, 03 Aug 2015 16:11:30 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2d4ff243-847b-42fd-9417-b8571975fd8cnejcokle<p>Also note that all leds shine only if i configure them as output. They don&#39;t shine otherwise. (in this example)</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/31000?ContentTypeID=1Mon, 03 Aug 2015 16:07:40 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5b9506e3-aaae-41b9-89af-94fe5a5e5cbcnejcokle<p>yeah it looks like example is using pins. I can&#39;t think of anything else why this shouldn&#39;t work. Do you maybe have any idea how i could check that?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/30999?ContentTypeID=1Mon, 03 Aug 2015 16:03:21 GMT137ad170-7792-4731-bb38-c0d22fbe4515:41c98590-2806-4bb1-84aa-bc56db38d69aSusheel Nuguru<p>I&#39;m sorry not to mention that, i was just testing if the LEDs are working with gpio functions and I used blinky example to test it. I have not tested it with dual mode example. But I do not see why they should not work, unless the example is using those pins for something else.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/30998?ContentTypeID=1Mon, 03 Aug 2015 15:57:33 GMT137ad170-7792-4731-bb38-c0d22fbe4515:abbf7cb6-8bed-4189-89ca-86874a5a2794nejcokle<p>But these commands work perfectly with blinky example.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/30997?ContentTypeID=1Mon, 03 Aug 2015 15:49:34 GMT137ad170-7792-4731-bb38-c0d22fbe4515:aa65e627-99d7-4ef5-ac32-b0b5c9123805nejcokle<p>Nope, doesn&#39;t work for me. I tried again, and changed <code>BLE_STACK_SUPPORT_REQD S130 BOARD_PCA10028 BSP_DEFINES_ONLY SOFTDEVICE_PRESENT NRF51</code> to <code>BLE_STACK_SUPPORT_REQD S130 BOARD_PCA20006 BSP_DEFINES_ONLY SOFTDEVICE_PRESENT NRF51</code> and when i use <code>LEDS_CONFIGURE(LEDS_MASK);</code> command, all 3 leds start shining.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/30996?ContentTypeID=1Mon, 03 Aug 2015 11:23:49 GMT137ad170-7792-4731-bb38-c0d22fbe4515:37e0438c-8c0d-4408-ba89-40a188e7bab6Susheel Nuguru<p>just tested it, works fine here.</p><div style="clear:both;"></div>
