This is a simple demo that we will use on the upcoming Espressif DevCon23.
ESP32 variant: https://github.com/JurajSadel/esp32-no-std-async-mqtt-demo
ESP32S3 variant: https://github.com/JurajSadel/esp32s3-no-std-async-mqtt-demo
The application measures temperature (BMP180
) and sends the results to MQTT
via WiFi - everything is done asynchronously.
It's async no_std
application that uses esp-hal, esp-wifi, and rust-mqtt crates. The main skeleton is made of embassy_dhcp and no_std_temperature_logger with a bunch of changes.
The first change is MQTT
part added. We are using MQTTv5
. As a broker, we usepublic-mqtt-broker and websocket-client to see the results.
As a next change, we had to make bmp180.rs async
.
You have to set the SSID
and PASSWORD
environment variables before building/running the program
