Device Status
Get Status
4254C–MP3–03/06
The Host employs the DFU_GETSTATUS request to facilitate synchronization with the device.
This status gives information on the execution of the previous request: in progress/OK/Fail/...
The device responds to the DFU_GETSTATUS request with a payload packet containing the fol-
lowing data:

Description
An indication of the status resulting from the execution of the most
recent request.
Minimum time in milliseconds that the host should wait before sending
a subsequent DFU_GETSTATUS. The purpose of this field is to allow
the device to dynamically adjust the amount of time that the device
expects the host to wait between the status phase of the next
DFU_DNLOAD and the subsequent solicitation of the device’s status
via DFU_GETSTATUS.
An indication of the state that the device is going to enter immediately
following transmission of this response.
