# esp32 Demo Application This Demo App is based on the console example from ESP-IDF, which can be found here relative to the ESP-IDF SDK root folder: - `examples/system/console/advanced/` ## Configuring for MQTT This application includes an option to send Memfault data over MQTT. This option requires a few extra pieces to set up. You can either follow the steps outlined here or use your own MQTT setup. ### Broker Setup 1. Install a local installation of Cedalo by following the [installation guide](https://docs.cedalo.com/management-center/installation/) 2. Login to Cedalo at <http://localhost:8088> 3. Create a new client login for the device - Ensure device client has the "client" role to allow publishing data 4. Create a new client login for the Python service - Ensure Python service client has "client" role to allow subscribing to data ### Service Setup 1. Modify the script found in Docs->Best Practices->MQTT with Memfault with the the following: 1. The service client login information previously created 2. Connection info for your local broker 3. Map of Memfault projects to project keys 2. Start the service by running `python mqtt.py` ### Device Setup 1. Make the following modifications to `main/app_memfault_transport_mqtt.c`: 1. Update `MEMFAULT_PROJECT` macro with your project's name 2. Update `s_mqtt_config` with your setup's IP address, and MQTT client username and password 2. Clean your existing build with `idf.py fullclean && rm sdkconfig` 3. Set your target: `idf.py set-target <esp32_platform_name>` 4. Build your image: `idf.py -D SDKCONFIG_DEFAULTS="sdkconfig.defaults;sdkconfig.mqtt" build` 5. Flash to your device using `idf.py flash`
