Prerequisite

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

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 <PROVIDER NODE ID> 0 0 0 <REQUESTOR NODE ID> 0

Once the transfer is complete, OTA requestor sends ApplyUpdateRequest command to OTA provider for applying the image. Device will restart on successful application of 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
