How to add the DFU OTA with SMP to a matter sample project like light_bulb

[paper555]

I would like to add smp ota firmware upgrade to the matter sample project, can you provide me with the specific steps to do so, and in which path is the ota file compiled and generated?

Hi,

Which protocol do you want to do OTA over? Matter or Bluetooth LE?

According to the description here, is it possible to support both matter OTA and smp OTA firmware upgrades on the device, and if I want to add smp OTA to the matter example project, how should I do it, and is there a detailed description of the steps?

[Sigurd Hellesvik]

Some of our Matter samples has OTA support. See for example Matter Thermostat: Device Firmware Upgrade support. Is this what you are looking for?

It is mentioned here that there are two ways of upgrading, one is the MATTER standard ota upgrade and the other is the smp protocol ota upgrade. I would like to ask how to do the ota upgrade through smp, besides configuring DCONFIG_CHIP_DFU_OVER_BT_SMP=y, what other steps are required, such as whether LE broadcasting needs to be enabled, through which APP how to operate the upgrade, etc.
