0x02 Supported Function Pages

This function returns the list of supported function pages by the device.

Request

Because a single report might not be enough to get the full list, the list may have to by fetched by parts. For this reason the function supports getting the list starting at a certain index, which is indicated by the start_index argument.

The first time you call this, you will probably want to set start_index to 0 and then re-call the function with an incremented index if there are still elements left in the list.

Table 5 - Supported function pages request argument structure (data section)

byte	0	1 .. End
description	start_index

Reply

The reply contains the number of elements returned, the number of elements left and the list elements.
