How to make MQTT work with an ESP8266 WiFi module on a STM Nucleo board?
Hi guys,
my setup is: a STM Nucleo F411RE board, an ESP8266 WiFi module connected to Serial6's TX/RX pins and – as a start – a DHT22 temperature / humidity sensor. What would I need to post sensor data to an MQTT broker like the open data one over at opensensors.io?
I can already talk to the ESP8266 via a library I found here on mbed (but that's sending only the AT commands to the ESP8266) and I can already read the DHT22 sensor data. For now I'm just printing them to CoolTerm on my Mac but I want to send them to a Mosquitto platform like opensensors.io.
The only problem is: how to make stable HTTP(S) requests via the ESP8266 ... :(
Any help much appreciated!
Thanks, Stefan.
