16..19 | File Version | Will contain the value initially set in the Query Next Image Response / OTA Query Next Image Response frames by the Host. |
20..23 | File Offset | |
24 | Maximum Data Size | N < 50 |
Effect on Receipt
The Host must process and respond to Image Block Request messages until the Module sends a Upgrade End Request
The Host must set status to MALFORMED_COMMAND (0x80) and return a 0 length data block if the Image Offset is outside the range of the file length.
Allowed Context
All Contexts.

( 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.
