Hi David:
1. Does MQX has support for nanoSSH ?
nanoSSH is not included in MQX release package, I think you can buy nanossl directly from Mocana. MQX 4.2 has cysssl support for Kinetis.
2. Does MQX support MQTT ?
MQX v5 support MQTT, but MQX v4.2 not support it,
3. Does MQX has support for 802.1x protocol ? We want to have WPA Enterprise level security for the platform.
No, MQX not support 802.1x, customer needs to implemented by himself.
Regards
Daniel
