How do i use a single serial port to communicate with the server and do a background dfu at the same time.

Hi,

I am using 

• nRF52840
• SDK 15.3.0
• Keil IDE
• The soft device is S140 
• JLinkRTTViewer for debug

How do i use a single serial port to communicate with the server and do a background dfu at the same time.

dfu uses the slip protocol and the application program uses a different protocol.

How can I receive messages from dfu and application using a single uart?

Please advise.

Hi Alex, 

we do not support concurrent background DFU and custom application commands over the same serial interface. If you want to add this feature then you will have do modify the DFU protocol to support this. We do not have any example code for this. 

Best regards
