losant-mqtt-esp-idf

ESP-IDF MQTT Client for connecting devices to the Losant IoT Platform

Usage

• add Losant info to a cfg.toml file in your crate root (make sure to .gitignore!); see cfg.example.toml

use esp_losant_mqtt::Device;

# TODO

• see the examples dir

• refer to the Losant docs for message limits

Running examples

• add Losant and wifi info to a cfg.toml file in the crate root (make sure to .gitignore!); see cfg.example.toml

• if using WSL, use usbipd to expose a USB device to WSL (Microsoft docs)

  • install usbipd in a PowerShell/CMD terminal

    # all of the following require admin mode
    winget install --interactive --exact dorssel.usbipd-win
    usbipd wsl list # may need a new terminal window to refresh env
    usbipd wsl attach --auto-attach --busid <BUSID>
    

  • check that the device is accessible within WSL

    lsusb # e.g. Bus 001 Device 002: ID 303a:1001 Espressif USB JTAG/serial debug unit
    

• run the esp32-c3-devkit-rust-1 example; replace the --target argument with your board's respective compiler target

  • using espflash v2

    cargo run --example=esp32-c3-devkit-rust-1 --release --target=riscv32imc-esp-espidf
    

  • using cargo-espflash v2

    cargo espflash flash --monitor --example=esp32-c3-devkit-rust-1 --release --target=riscv32imc-esp-espidf
    

  • using espflash v2 (manual)

    cargo build --example=esp32-c3-devkit-rust-1 --release --target=riscv32imc-esp-espidf
    espflash flash --monitor target/riscv32imc-esp-espidf/release/examples/wifi
