wolfSSL Example Project: wolfMQTT for AWS IoT

This is an example based on the AWS IoT Example.

Getting Started

The easiest way to get started is by using the Espressif Managed Component Registry at https://components.espressif.com

The latest experimental development version can be found at the staging site: gojimmypi/mywolfmqtt.

#!/bin/bash

. ~/esp/esp-idf/export.sh

# Needed for Staging site:
export IDF_COMPONENT_REGISTRY_URL=https://components-staging.espressif.com

idf.py create-project-from-example "gojimmypi/mywolfmqtt^1.0.14-test:AWS_IoT_MQTT"

cd AWS_IoT_MQTT

idf.py -p /dev/ttyS9 -b 921600 flash monitor -b 115200

Prerequisites

It is assumed the ESP-IDF environment has been installed.

Files Included

• main.c with a simple call to an Espressif library (ESP_LOGI) and a call to a wolfSSL library (esp_ShowExtendedSystemInfo) .

• See components/wolfssl/include directory to edit the wolfSSL user_settings.h.

• Edit main/CMakeLists.txt to add/remove source files.

• The components/wolfssl/CMakeLists.txt typically does not need to be changed.

• Optional VisualGDB Project for Visual Studio using ESP32 and ESP-IDF v5.1.

• Edit the project CMakeLists.txt to optionally point this project's wolfSSL component source code at a different directory:

set(WOLFSSL_ROOT "~/workspace/wolfssl-other-source")

Getting Started:

Here's an example using the command-line idf.py.

Edit your WRK_IDF_PATHto point to your ESP-IDF install directory.

WRK_IDF_PATH=/mnt/c/SysGCC/esp32/esp-idf/v5.1

echo "Run export.sh from ${WRK_IDF_PATH}"
. ${WRK_IDF_PATH}/export.sh

# build the example:
idf.py build

# flash the code onto the serial device at /dev/ttyS19
idf.py flash -p /dev/ttyS19 -b 115200

# build, flash, and view UART output with one command:
idf.py flash -p /dev/ttyS19 -b 115200 monitor

Press Ctrl+] to exit idf.py monitor. See additional monitor keyboard commands.
