How to Make nRF52840 as Zigbee HA1.2 Coordinator

[uldara]

HI i want to use nRF52840 as Zigbee HA1.2 Coordinator, how to coding ? 

nRF52840 support this stack or not ?

Thank

Hi UL Dara, 

the nRF52840 comes with a Zigbee PRO stack, see Zigbee stack features and you can find examples in the nRF5 SDK for Thread and Zigbee . I suggest taking a look at the Zigbee Light Control example, it provides a minimal implementation of the following devices:

• Light coordinator - demonstrates the Zigbee Coordinator role, which supports only the network steering commissioning mechanism.
• Light switch - demonstrates the Zigbee End Device role, implementing the Dimmable Light Switch profile.
• Light bulb - demonstrates the Zigbee Router role, implementing the Dimmable Light profile.

Best regards

Bjørn

I bought some modules from market that support ZigBee HA1.2 

and i want to use nRF52840 as ZigBee Coordinator, 

I tested example Light coordinator but Sensor module not joint to this coordinator 

and I see nRF52840 running on ZigBee 3.0 that why i don't know how to make it work with Zigbee HA1.2

Thank

The Zigbee 3.0 specification is backwards compatible with the Zigbee Home Automation 1.2 profile, as long as the Zigbee 3.0 device is configured as such. So our Zigbee 3.0 stack should be backwards compatible with Zigbee Home Automation (HA) 1.2 devices. The limitations are listed below

• A Zigbee Home Automation device can join a Zigbee 3.0 Centralized Network that does not require a key exchange.
• A Zigbee Home Automation device can NOT join a Zigbee 3.0 distributed network.
• A Zigbee 3.0 device can join either a Zigbee Light Link or a Zigbee Home Automation network using classical commissioning.

Thank you bjorn-spockeli

i just start up on ZigBee

do you have sample code for this option ?

Thank 

[bjorn-spockeli]

No, I do not think we have any example where a nRF52840 communicates with a HA1.2 device out of the box. The examples we have in the SDK doesn't contain the secret key required for Zigbee authentication. You would need to be a Zigbee alliance member to acquire the key.

Dear bjorn-spockeli

secret key required for Zigbee authentication is "5A:69:67:42:65:65:41:6C:6C:69:61:6E:63:65:30:39"
