CHIP ESP32 OTA Requestor Example

A prototype application that demonstrates OTA Requestor capabilities.

Prerequisite

Before moving ahead, make sure you have OTA Provider is commissioned and running.

Supported Devices

• This example supports ESP32 and ESP32C3. For details please check here.

Building the Example Application

• If you are building for the first time please check Building the Example Application guide.
• Otherwise, idf.py build works!

Flashing the Example Application

idf.py -p <OTARequestorSerialPort> flash monitor

Commissioning over BLE using chip-tool

• Please build the standalone chip-tool as described here
• Commissioning the OTA Requestor

./out/debug/chip-tool pairing ble-wifi 12346 <ssid> <passphrase> 20202021 3840

Query for an OTA Image

After commissioning is successful, announce OTA provider's presence using chip-tool. On receiving this command OTA requestor will query for OTA image.

./out/debug/chip-tool otasoftwareupdaterequestor announce-ota-provider 12345 0 0 12346 0

Apply update request

Once transfer is complete OTA Requestor should take permission from the OTA Provider for applying the OTA image. Use the following command from OTA requestor prompt

esp32> ApplyUpdateRequest

Then reboot the device manually to boot from upgraded OTA image.

ESP32 OTA Requestor with Linux OTA Provider

• Build the Linux OTA Provider
• Run the Linux OTA Provider with OTA image.

./out/debug/chip-ota-provider-app -f hello-world.bin

• Provision the Linux OTA Provider using chip-tool

./out/debug/chip-tool pairing onnetwork 12345 20202021
