NBIOT will it support TLS for making MQtt connection

@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?

[solved] MQTT and tls

Just want to share actual working sample. NOTE: Checking server certificate is DISABLED in this case. You need CERT_REQUIRED or CERT_REQUIRED judging from documentation. But, by some reason in my build ussl.CERT_REQUIRED gave "...object has no attribute...". # --------------------------------------------- # Tested setup: # - Traefik Proxy 2.5 (Let's Encrypt Cert) # - Mosquitto 2.0.16 # - MicroPython 1.17 # ---------------------------------------------- from umqtt.simple import MQTTClient HOST = "" # Without server_hostname it wan't connect (by some reason) ssl_params = {"server_hostname": HOST} c = MQTTClient("", server=HOST, port=8883, user="", password="", # Need keepalive > 0 or got MqttException(2) keepalive=10, ssl=True, ssl_params=ssl_params)

Restrict TLS to V1.2 only

Hello,

Is TLS1.2 well implemented in the current FiPy Firmware? i have to ask because I cannot find any of the corresponding flags in the fipy ussl documentation.

I have to pretend a fallback to TLS V1.1. in my application.

Hello, I'm having a similar problem when trying to connect using EAP-PEAP. Has anyone gotten any results? Thank you.

SNI on TLS connections?

Sorry, looks like this was my fault. Looks like it is working as intended but I messed something on the server. Got to do some more testing though... @jmarcelino (btw, congrats for you position at pycom), Still you might wanne document the parameter server_hostname on the ussl.wrap_socket function. A just noticed that cert mismatch does not rise ussl.SSLError but OSError which is therefore wrong in the docs too.
