I need to implement MQTT protocol on an ELS61 module via AT-commands.
Does anyone have some hints or examples to do this.
Many thanks in advance
We have only an example implementation in Java: https://iot-developer.thalesgroup.com/showcase/concept-board-connection-...
There is an additional library used that implements MQTT. For AT commands you need to have MQTT layer in your software. You can then use IP services over AT commands (you can open a transparent connection or use commands to send and receive data). There are examples in AT commands specification, you can also find additional examples in the Knowledge Base, for example: https://iot-developer.thalesgroup.com/knowledge-base?title=internet%20se...
We have a demo of the new JAT Java AT command extention interface here.
The demo shows how to use our Java MQTT client via AT^SJMQTT :)
A good (3rd party) MQTT client for an iPhone :

This is not supported by Gemalto but works nicely.
