Arduino library for publishing UPT Measurements to an MQTT broker.
It offers conveninence method to publish UPT Measurements while simplifying the interface to the ESP-IDF mqtt_client library.
Optionally it can handle Wi-Fi connectivity.
It is not yet available through library managers.
This project was developed and tested on Espressif ESP32 DevKitC and Lilygo T-Display S3 hardware.
We recommend using the PlatformIO VSCode extension to compile and flash the code in this example. You will find more instructions here
It is also possible to use the application using Arduino IDE. You will find more instructions here
Two example scripts are available in the examples folder:
-
delegatedWifiUsage: In this example the main application delegates the WiFi management to the MQTT client. Such approach should be used if your application does no use Wi-Fi overwise and you do not want any fancy Wi-Fi configuration.
-
selfManagedWifiUsage: In this example the main application will handle the WiFi management, and the MQTT client will not care about it. Such approach should be used in most cases since your application will likely use WiFi for other things.

This library uses the following dependencies.
- Arduino ESP32 (In particular, the Wi-Fi library, message logging and MQTT client) \
- Sensirion UPT Core
