CC2531: ZAP and Node.js

Corduant Corduant

Part Number: CC2531

Hello,

I'm currently try do simulate a zigbee pro device with a cc2531 dongle. I flash it with the Zstack and I have a node.js backend witch is able to communicate with the dongle.

I have a raspberry pi and a ti CC2531 usb dongle and I want, as quickly as possible, create and send some zigbee data to a zigbee device.

But is not enough to create easily a zigbee communication.

I use : https://github.com/zigbeer/cc-znp/wiki/6.-Z-Stack-MT-API-Reference-Tables#64-zdo-table to communicate with the dongle directly. It works fine, I'm able to ping the device and I' m able to get device information. But it's hard to create zigbee communication. Is it a "zigbee workflow" available to create a proper API to pair, un pair, send and receive zigbee data, etc... ? I don't know much about zigbee protocol and configuration.

So I'm trying to find a new way using ZAP. Can you give me some explanation, exemple, raspberry software implementation to run an ZAP application on the raspberry and create some connectors to the dongle and node.js ?

Thanks a lot, and happy new year !

You can try the ZNP host framework(www.ti.com/.../tidu757.pdf ) which is similar to what you are using but in C language. You should be able to compile and run the example applications which can initialize the CC2531 as a Coordinator, router, or en device

You can clone the project from here git.ti.com/.../znp-host-framework

Try to refer to e2e.ti.com/.../3286.CC2530ZNP-Interface-Specification.pdf

Thanks a lot for the answer.

I take a look to the project and yes, is exactly what I want but in C.

However, the exemple, servDisc, or DataSendRecv are very interesting. maybe, the easiest way for me is to "copy" the C workflow, to implement it with my javascript ZNP library.

Is there some documentation with the workflow to use ZNP command and :
- create a zigbee network
- send data
- recive data
- ...
- ....
Because, with this I will be able to implement each of this scenarios in javascript directly.
I can do the job and copy the C implementation but if the information already exist it will be great.

Thanks a lot,

Franck

I am not aware any of detail document about this. You can also try to refer to the following links:

In the document previously shared by YK (ZNP Interface specification) you can check section "3.2 CC2530-ZNP startup procedure " which explains which commands you should use to initialize the device

Thanks a lot again for your answsers.

I do what explained in 3.2 but how to connect my endevice (Ti dongle) to my zigbee gateway. When I do the procedure, I don't see anything on my Sniffer (TI CC2531 USB dongle in sniffer mode).

Sorry, I click reply to quickly.

I see packets from my gateway, my gateway is in commissionning mode.

But nothing from my end device.

If i supposed the startup configuration is fine, what can I do now the initialise a communication with my gateway ?

Thanks,

If you configure device correctly, it should send beacon requests to try to join Zigbee network. However, you didn’t see beacon requests in your sniffer so I suggest you to check your steps again.
