Hello,
Thanks for this sample code. I tried compiling and running it on my STM32 target and out of the box, I get a Mutex Lock Failed assertion. When I increased the "events.shared-stacksize" to 8192, the program seems to hang on "Starting TLS handshake with os.mbed.com".

I then set "tls-socket.debug-level" to 2 so that we get more information in the trace logs. That log file is attached. Any idea what could be going on? Let me know if you need further info.

Compiler : GCC_ARM version 7.3.1
Target : NUCLEO_F767ZI
