Platformio project for an ESP32 using ESP-IDF

This is a sample project for integrating Memfault with a PlatformIO project using the ESP-IDF framework.

Setup

1. Install PlatformIO CLI using the instructions here.

2. Initialize Memfault submodule:

git submodule update --init

3. Activate the PlatformIO virtual env

source ~/.platformio/penv/bin/activate

4. Install Memfault's dependencies

pip install -r src/memfault/memfault-firmware-sdk/requirements.txt
pip install memfault-cli

Testing

1. Build with the platformio CLI:

pio run

2. Upload the symbol file to Memfault:

memfault \
--org-token $MEMFAULT_AUTH_TOKEN \
--org $MEMFAULT_ORG_SLUG \
--project $MEMFAULT_PROJECT_SLUG \
upload-mcu-symbols .pio/build/espidf/firmware.elf

3. Flash the device and start the serial monitor

pio run --target upload --target monitor

4. Join a wifi network

esp32> join <ssid> <password>

5. Save wifi settings to NVM so it connects automatically on boot

esp32> settings_set "wifi_ssid" "your network name"
esp32> settings_set "wifi_password" "your-wifi-password"
