### Uses
|
|
|
|
- An MQTT client is required to operate the phone.
|
|
- The smsquittod.py module gives an example of a client written in python.
|
|
- The library used is that of the Eclipse foundation: pahon-mqtt
|
|
- It will suffice to implement the ClientMQTTBase class
|
|
|
|
- The sms-client-test.html file is another example but in websocket mode.
|
|
- It will suffice to directly modify the html file
|
|
- we launch it directly in a browser
|
|
- by drag and drop
|
|
- by an address of this type
|
|
- file: ///path/du/fichier/sms-client.html
|
|
|
|
- demonstration
|
|
|
|
- sms-client-test.html is fully functional
|
|
- You just have to update the apikey in this file and in the configuration file on the mobile phone
|
|
- And set up some mobile numbers to do the tests
|
|
|
