Florian b2c05156b2 Srfb bugs (#807) 
* Correct buffer processing

was missing an instruction due to a previous refactoring

* Correct duplicate condition

* Avoid publishing \n into the raw value

* Merge extract_char and value_from_service_data functions

OpenMQTTGateway - ESP8266 or Arduino program for home automation
Act as a wifi or ethernet gateway between your 433mhz/infrared IR signal and a MQTT broker
Send and receiving command by MQTT
This program enables to:
- receive MQTT data from a topic and send signal (RF, IR, BLE, GSM) corresponding to the received MQTT data
- publish MQTT data to a different topic related to received signals (RF, IR, BLE, GSM)
