CCS/LAUNCHXL-CC2640R2: Serial output terminated but application is still running

Part Number: LAUNCHXL-CC2640R2
Other Parts Discussed in Thread: CC2640R2F

Tool/software: Code Composer Studio

Hello TI,

I'm having a really annoying issue where the serial output from my application gets terminated after some time.

I am using the CC2640r2f launchpad, CCS v8 and running on Windows 10.

Now I'm simply running "project_zero_cc2640r2lp_app" and connecting to it via the simple link iPhone app. It runs, and when I open a serial monitor to observe the data, it prints for 5-50 seconds and then just stops outputting. The app is still running although the serial output has quit printing the data, as I can control it through the app. To be able to observe the serial output I have to unplug the launchpad and plug it back in, restarting does not do the trick.

I have tried using different serial monitors (PuTTY, TeraTerm, etc.), different usb cables, different example project (happens the same when running e.g. display example), made a new workspace and used two different launchpads, but still I can only print the output for a short amount of time.

This is a really annoying problem, so if you have some idea what can be done to fix this it would be really appreciated.
