ESP8266, MQTT, GSM

[lakmalp]

Hi,

I have a requirement to send sensor data (wireless) to a hub and forward that information as text messages to a mobile phone. My plan is to use ESP8266 to transmit sensor data over wi-fi. As I have heard, RPi 3 comes with built-in wi-fi.

Can I configure RPi as a Wi-Fi access point and install MQTT broker in the same RPi so that I can receive data send from sensors and forward it to GSM module?

If above arrangement is not feasible, can you please propose a way to do it?

My requirement is to collect (wireless) sensor data by a central unit and forward that data to a phone as an SMS.

Thanks in advance,

Lakmal

That seems like a very sensible design.

Get Mosquitto from http://mosquitto.org/2013/01/mosquitto- ... epository/ (not from the ancient version that's part of Raspbian).

The latest version from the mosquitto repo includes websockets which you could drive from your ESP8266s as that's easier than having to build MQTT client code on there.

Sorry for the late reply. I will read more about websockets and your suggestion and will post if I would like to know more information.

Thank you for helping me out... (Y)
