We are today using paho and this MQTT wrapper: https://github.com/mangOH/MqttClient/tree/use_paho_linux_version developed by @dfrey and others to connect to our own mosquitto broker with TLS encryption.
But I’m now trying to connect to google’s mqtt bridge with TLS and JWT. But I get a socket error when trying to connect. Not sure how to investigate this further but I think this may be a clue?
Is there a known issue connecting to gcloud with sierra (WP85) and this wrapper or have someone made it work?
