The BLE/Ant were both running on the older eval board. I added a BLE attribute, and that&#39;s what started the communication problems started. I took the additional attribute out and still had the comm problems. I was able to get it to work buy only be disabling all the Notify characteristics in my BLE Attributes. It runs better on the PCA10028 board, but it has occasional comm problems too.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/19741?ContentTypeID=1Fri, 20 Feb 2015 15:42:29 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7cd05e1d-fe45-4768-910f-d200f34260d6Petter Myhre<p>I&#39;m not sure what the problem could be. Do you have any projects and test setup you could share so that we can try to reproduce it here?</p><div style="clear:both;"></div>
