https://devzone.nordicsemi.com/f/nordic-q-a/32986/infinite-gatt-connectionHi, Is it possible to make infinite GATT connection ? I set auto connect in android central app and my program in nrf51DK works. But only 4 hours. Hardfault is almost regularly occured after 3h45min or 4h and I realy don&#39;t know what. I need infiniteen-USTelligent Community 13Tue, 10 Apr 2018 06:54:02 GMThttps://devzone.nordicsemi.com/thread/127526?ContentTypeID=1Tue, 10 Apr 2018 06:54:02 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b20355b6-a339-4570-b7e4-a5b2e84a4badJackxl<p>It is easy. I set timer to 1 minute and then I use counter for minutes. When counter is ten, I will notify characteristic.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/127486?ContentTypeID=1Mon, 09 Apr 2018 15:36:55 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4c394893-e406-44f4-85dc-d6240e37f683Kenneth<p>How have you implemented sending one characteristic every 10minutes? By default the max prescaler for app_timer allow about 4minutes before it will wrap around.&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/127174?ContentTypeID=1Fri, 06 Apr 2018 09:14:26 GMT137ad170-7792-4731-bb38-c0d22fbe4515:057f0988-a2f8-4f61-90e6-e07d7e649f7cTurbo J<p>Don&#39;t.

My application only sending notification for one characteristic to android phone&nbsp;each 10minutes after connection is established. Nothing else, there is no thing which can overflow. I using SD7 and SDK7.2.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/127110?ContentTypeID=1Thu, 05 Apr 2018 16:09:23 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c0955411-8b2a-4385-b9ca-90144bba9104Kenneth<p>We are not aware of any issues in the softdevice that may prevent infinite GATT connection. Likely your application is doing an operation that for instance overflow after a few hours, and thereby you do an illegal operation that cause the chip to hardfault. Maybe you are able to set a breakpoint in the hardfault handler, read out the CPU registers, thereby you can find the program counter (pc) that cause the fault in the first place.</p> <p>What SDK and SD are you using?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/126577?ContentTypeID=1Tue, 03 Apr 2018 06:36:54 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7b338eec-1a6f-4939-8363-4ec2a217425aJackxl<p>What ?
