802.15.4 compatibility

[kbu]

Hi,
I'm curious if the RF data from applications written with the freescale 802.15.4 library running on freescale hardware (MC1321x) be compatible with say a 802.15.4 library running on a chipcon (or other) system?
I'm not looking for zigbee interop though.

has anyone tried this?
thanks.

HI:

Each manufacturer has its own implementation of the 802.15.4 in their chips (registers are different, etc). Therefore, libraries from one vendor won't works with another vendor's chips.

Regards,

Alex.

Sorry, So I meant if at a RF level the data would be the same.. i.e. chipcon chip receiving data from a freescale chip.

If they are both IEEE-802.15.4 compliant, then they should be able to talk to each other.

However, what would they say?

The IEEE-802.15.4 standard only specifies communication up to the MAC layer. So it specifies HOW to communicate, but not WHAT to communicate.

They should be able to connect to the same PAN, but that's about all. Both the Freescale part and the Chipcon part would need to have the same application protocol written above the MAC layer.

Which would be the case if the application was ZigBee.
