Over-the-Air (OTA) Service

Example Brief

This example demonstrates how to configure the Over-the-Air (OTA) Service to update application and data partitions in the ESP-ADF.

This example can upgrade data partitions from the microSD card by configuration. Here the example demonstrates upgrading the Voice Tone data partition from the microSD card. Also, this example demonstrates getting an application binary firmware update upgrade from an HTTP server.

Environment Setup

Hardware Required

This example runs on the boards that are marked with a green checkbox in the table. Please remember to select the board in menuconfig as discussed in Section Configuration below.

Build and Flash

Default IDF Branch

This example supports IDF release/v5.0 and later branches. By default, it runs on ADF's built-in branch $ADF_PATH/esp-idf.

Configuration

The default board for this example is ESP32-Lyrat V4.3. If you need to run this example on other development boards, select the board in menuconfig, such as ESP32-Lyrat-Mini V1.1.

menuconfig > Audio HAL > ESP32-Lyrat-Mini V1.1

First, configure the Wi-Fi connection information. Go to menuconfig > OTA App Configuration and fill in the Wi-Fi SSID and Wi-Fi Password.

menuconfig > OTA App Configuration > (myssid) WiFi SSID > (myssid) WiFi Password

Then, configure the HTTP server URI address where the firmware to upgrade to is obtained. Go to menuconfig > OTA App Configuration and fill in the firmware upgrade uri.

menuconfig > OTA App Configuration > (http://192.168.5.72:8080/play_mp3_control.bin) firmware upgrade uri

This example supports upgrading data partitions from microSD card. Go to menuconfig > OTA App Configuration and fill in the data image upgrade uri.

menuconfig > OTA App Configuration > (file://sdcard/flash_tone.bin) data image upgrade uri

Fill in the name of the selected data partition. Go to menuconfig > OTA App Configuration and fill in the data partition label。

menuconfig > OTA App Configuration > (flash_tone) data partition label

This example does not check the firmware version number by default. You can enable the Force check the firmware version number when OTA start option to force a firmware version number check.

menuconfig > OTA App Configuration > Force check the firmware version number when OTA start

Prepare a microSD card with the voice tone binary file flash_tone.bin to update the Voice Tone partition data.

Build and Flash

Build the project and flash it to the board, then run monitor tool to view serial output (replace PORT with your board's serial port name):

idf.py -p PORT flash monitor

To exit the serial monitor, type Ctrl-].

See ESP-IDF Programming Guide for full steps to configure and build an ESP-IDF project.

How to Use the Example

Example Functionality

  • Fist of all, run a Python script with python 2.7. The development board and HTTP server should be connected to the same Wi-Fi network. The Python script log is as follows:
python -m http.server -b 192.168.5.72 8080
Serving HTTP on 192.168.5.72 port 8080 (http://192.168.5.72:8080/) ...
192.168.5.187 - - [25/Nov/2021 16:13:37] "GET /play_mp3_control.bin HTTP/1.1" 200 -
  • After the example starts running, it connects to the Wi-Fi hotspot as configured by default. After a successful connection, it first updates the data in the flash_tone partition. The log is as follows:
