Hi,
You can use the socket to add SSL:

import socket
import ssl
s = socket.socket()
ss = ssl.wrap_socket(s)
ss.connect(socket.getaddrinfo('google.com',443)[0][-1])

The information is here: http://docs.pycom.io/tutorials/networkprotocols/https/

@Gijs Isn’t NB-IoT (often) restricted to UDP only?

[Gijs]

Sorry, I was not aware of that!

@Gijs I never used it so I'm not completely sure, but I believe it is. Not sure whether that's part of the specs or if it's a limitation from the carriers (and could thus be difference between carriers), though.

If someone has a definitive answer...

I've used the simple mqtt library (and robust mqtt). It includes an argument just set ssl=True in client.connect(...). Worked for me.

@randomrnti Just curious, which NB-IoT network would be that? Is it via PyCom Vodafone NB-IoT sim? or you have setup a MQTT Server on a dedicated server and made that server reachable from Vodafone NB-IoT SIM?
