I am using Proximity , UART and DFU from nrfToolbox app. I have 3 buttons on my home screen dedicated for each of them. I need to send/receive some data using Imediate alert and some using UART.

Actually I am new to android. I tried to combine them at first but couldn&#39;t succeed because proximity uses multi connection and UART uses single. I have tried changing proximity to single connection so that I could combine them but if I do so my app is not working.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/104509?ContentTypeID=1Fri, 03 Nov 2017 14:15:38 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5674c5a6-c5a1-4df6-a5cd-e2f18d95ace2Sigurd<p>Hi,</p> <p>Then you need to do some coding, and combine them in the code so you don&#39;t have to go-back/connect again.</p><div style="clear:both;"></div>
