Also the release notes for each softdevice should state which IC variant it is tested to work with. If the IC variant is not mentioned, then it&#39;s not much that can be done with that.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/50733?ContentTypeID=1Mon, 09 May 2016 03:39:53 GMT137ad170-7792-4731-bb38-c0d22fbe4515:20c8e8ff-38af-4b29-87b9-de0fb50836b3Songplus<p>Thank you ,I have soluted the problem.BTW,I want to use the latest softdevice,but the device dosn&#39;t support the newest softdevoice,and my sold out production can&#39;t update the hardware.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/50732?ContentTypeID=1Wed, 20 Apr 2016 11:08:27 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b1d1a677-6899-4f93-ad2a-640070840522Kenneth<p>Hi, it should be no problem to use GATT client and server at the same time for any of our softdevices. The following example show how you can setup both in the same project: \ble_peripheral\ble_app_proximity You can follow the documentation on how to setup the example project. You should always try to use the latest available softdevice when developing.</p><div style="clear:both;"></div>
