In the application note “APS013: DW1000 and two-way ranging”, pg 6 - section 2.3.1 “General ranging frame format” there is a brief explanation of the frame format set out in the 802.15.4-2011 std.
Seeing as I don’t have a copy of the standard, nor would I fancy spending 255USD in acquiring this document, and Decawave’s documentation doesn’t provide a clear understanding of this issue beyond auto-appending of the FCS octet, I am turning to the forums for clarification.
Is anyone able to share information regarding the following:
In fig 4, there are hex values underneath the Frame Control and PAN ID octets, are these default values?
How much of these raw frames must be written/read by the host? Are we only meant to write the message portion? If note, is there any portion of the frame that is extracted from other registers (apart from the automatically incremented sequence number and the auto-generated CRC placed in the FCS octect) i.e. PAN ID, FC (Frame Control), Dest Addr, Src Addr etc… ?
If configuring a raw frame is necessary, does anyone have the bit encodings for the Frame Control, PAN ID, Dest Addr, Src Addr octets? Most importantly the Frame Control octets.
On a slightly related note: if writing and reading raw frames is not necessary, is a ‘range init’ frame sent automatically or does the host need to decode the blink frame and respond?
Any information or guidance would be greatly appreciated.
