LAUNCHXL-CC1352P: Changing pan and source address

carles lloret

Part Number: LAUNCHXL-CC1352P

Hello

I am just begining to investigate the cc1352 launchpad... I would like to send custom zigbee-like frames with a source address and a pan address chosen by m... instead of being assigned by the coordinator or the router.

I am modifying the zc_switch and the zed_switch. Here is my doubt I am using the zed (zigbee end device) code but the zed code responds with a beacon request... with no pan id nor source address... just the broadcast address (0xFFFF) .

I guess that the beacon request must always use the 0xFFFF and the source address 0xFFFF.

I suspect that the beacon request is needed in the zigbee network; a necessary handshake between the end_device, router and coordinator. However I would like to remove the handshake so the launchpad deliver only a frame... without a handshake. It is certainly possible... I am certain that it has been done it with the CC26XX.

Thank a lot.

I don’t think you can change beacon request with CC26x2/CC13x2 Zigbee Stack.

YK is right, beacon requests are broadcasts for which the Pan ID and short address are fixed. The ZED will attempt to join an open network for which a ZC has established a valid Pan ID and returns a beacon response. The ZC will stochastically assign a short address to the ZED during the association process. You can modify the join process by using a pre-determined network keys or install codes. Please refer to the Z-Stack User's Guide or Security SLA for more information. If you have the CC26XX solution then it should be portable towards your CC1352 firmware without too much difficulty, see the Migration Guides.

Shouldn't the CC13x2 be able to send a mac/zigbee frame without the handshake or checking for another zigbee? What I want is fast information from a cc1352 without any handshake with router or coordinator... I do not want to spend 1 sec used in this proces.

Thank you again.

Should I use propietary RF... ? If I want to send some frame that are outside the natural flow of zigbee, should I use propietary RF? I do not know what propietary RF is or what uses have... but could it be an option?

Thank you again.

The Prop RF stack is intended for solutions which require basic RF communication between devices without adhering to a Specification or expected communication scheme. If you do not need heightened security or mesh networking then it is most likely what you should consider using. Please see the Wireless Connectivity Technology Selection Guide.

I assume that the Prop RF could deliver zigbee-like frames that do not require handshaking nor any kind of dialog between nodes... could that be the case?

Thanks again. Carles.

You can use the IEEE 802.15.4 PHY and use frame data that replicates Zigbee packets, but this will be entirely proprietary protocol and not be able to communicate with any full Zigbee devices.

Ok perfect. So this is the protocol IEEE 802.15.4 PHY... could I send a zigbee packet among the normal zigbee protocol? in another channel and another PAN?

Thank you again.

It's a proprietary protocol using the IEEE 802.15.4 PHY, you can change channels and imitate a PAN selection but without the association/join process you cannot communicate within an existing Zigbee network.
