( PH:0xB0, SH:0x05 ) - OTA Image Block Response Command

Overview

The OTA Image Block Response frame is sent from the Host to the Module. The Module relays the frame to the OTA target device. If the target EUI64 is the module’s own EUI64, the module will process it locally.

There are three possible return values for the OTA Image Block Response: Success, Wait for Data, and Abort. The payload differs for each one.
