MatrixVoice PlatformIO

The current project show how build and upload any firmware for MatrixVoice ESP32 board using PlatformIO OTA or Arduino OTA.

note: The next documentation is based on Program Over the Air on ESP32 MATRIX Voice documentation but it using PlatformIO instead Arduino IDE. You dont need IDF toolchain or any library, PlatformIO do it for you.

Prerequisites

PlatformIO software

Please install first PlatformIO open source ecosystem for IoT development and its command line tools (Windows, MacOs and Linux). Also, you may need to install git in your system (PC).

MatrixVoice software

For get OTA updates without RaspberryPi, first you should have a one RaspberryPi with MatrixVoice software. Please run into your RaspberryPi shell or ssh:

add debian repository key:

curl https://apt.matrix.one/doc/apt-key.gpg | sudo apt-key add -
echo "deb https://apt.matrix.one/raspbian $(lsb_release -sc) main" | sudo tee /etc/apt/sources.list.d/matrixlabs.list

update your repository and packages:

sudo apt-get update
sudo apt-get upgrade

install the MATRIX init package:

sudo apt install matrixio-creator-init

reboot your Raspberry Pi:

sudo reboot

SSH back into the pi, execute this command:

voice_esp32_enable

Installing initial firmware for OTA

Return to your PC and clone this repository:

git clone https://github.com/hpsaturn/matrixvoice_platformio.git
cd matrixvoice_platformio

Copy platformio.ini sample and change your network parameters:

cp platformio.ini.sample platformio.ini

NOTE: plase change platformio.ini and set your SSID and PASSW like this:

'-DWIFI_SSID="MyWifiSsid"'
'-DWIFI_PASS="MyWifiPassw"'

building

pio run

upload

Enter to OTA directory and upload the firmware. Please replace the ip parameter with your RaspberryPi ip like this:

cd ota
./install.sh 192.168.178.65

The console output should be like this:

(master) avp:ota$ ./install.sh 192.168.178.65

[SUCCESS] Please disconnect your MatrixVoice from the RaspberryPi and reconnect it alone for future OTA updates.

(end of Prerequisites)

Upload via PlatformIO OTA

After that, you can using your MatrixVoice without RaspberryPi. For send new OTA updates, you only need:

pio run --target upload

For update MatrixVoice libraries in the future, you only need:

pio lib update

---

Troubleshooting

Uploading issues

If pio run --target upload not works, please check MVID parameter, it should be a short name, or you can passing ESP32 ip in upload_port parameter in platformio.ini file.

Building issues

For a complete clean of the project and get the last version of the libraries, please test the next commands:

git pull
pio run -t clean && rm -r .pio
pio run
