About mesh dfu, upgrade multiple devices at the same time.

With mesh dfu, whether to upgrade the firmware of many different devices at the same time is supported. Multiple device deployment spaces are adjacent, and simultaneous transmission of different firmwares will result in incorrect storage.

Hi.

With mesh dfu, whether to upgrade the firmware of many different devices at the same time is supported.

Yes, DFU of multiple devices at the same time is supported in BLE Mesh. 

More information about the DFU can be found in the Mesh DFU protocol section.
