nRF9160 MQTT with TLS disconnects if subscribing

Hi Håkon, thank you for responding

I was able to resolve the issue by reverting to the mqtt_simple example and re-tracing my steps.

The cause of the issue was use of some uninitialized data when subscribing to one of the MQTT topics. There was no error message, but stepping through the offending code caused the debugger to disconnect while the code continued executing seemingly normal.

Hi Jon,

Although there has been several releases of bsdlib since tag v1.2.0 (which is based on v0.6.1), this does not sound like a previously known issue, as per the changelog:

https://github.com/NordicPlayground/nrfxlib/blob/master/bsdlib/doc/CHANGELOG.rst

Could you share your project?

If it holds any code that you do not want to share publicly, please let me know, and I can make this case private.

Kind regards,

Håkon
