Packet capturing from the PHY layer

ZigBee
I have a CC2430 development kit with me. I need to sniff zigbee radio packets for one of my application. Is there any way out to get interfaced with PHY or MAC (802.15.4) for capturing zigbee packets? So, if anyone could give me some advice or pointers, I would really appreciate it.

Hi,

Hi, to sniff packages you don't have to capture them above the PHY layer. Just set the mdmctrl0 to another value. There is a bit for promiscouos mode. Set this to 1 and the MAC will forward all messages to the higher layers ;) I just built such a simple sniffer. But to get a good packet sniffer, I would propose to use the official chipcon packet sniffer ;) But to get back to the topic: I want to discard packages between PHY and MAC to test my whole network. Anyone ever tried this? I want to discard packages and ACKs. After first calculations it is possible to reach this without getting timing problems. I want to compare the addresses and if the address is the one to be filtered, this small filter shall discard the package and set the SACKPEND bit to a value, I want ;) Thanks
