Part Number: CC2652P
I am planning to create a zigbee coordinator on CC2652P using SIMPELINK-CC13X2-26X2-SDK Z-Stack with ZigBee 3.0 support.
I would like to know if the device will be interoperable with legacy ZigBee PRO HA,SE and ZLL devices. my network has some old sensors and lights and meters based on legacy HA,SE and ZLL on ZigBee PRO.
I wanted to understand if its possible to join the legacy devices to the ZigBee 3.0 based coordinator and retrieve data from the legacy devices.
Is there any documentation present for interoperability between zigbee 3.0 and legacy devices?
SIMPLELINK-CC13X2-26X2-SDK v4.30 Z-Stack 3.0 Coordinators will allow legacy devices to join if BDB_DEFAULT_TC_REQUIRE_KEY_EXCHANGE is FALSE (default). There are several relevant E2E threads which can be referenced.

For HA and ZLL devices, it's interoperable as Ryan mentioned to set BDB_DEFAULT_TC_REQUIRE_KEY_EXCHANGE to FALSE but SE profile device is usually another story which is not compatible to Zigbee 3.0.

In reply to Ryan Brown1:
Thanks for the response.
what does BDB_DEFAULT_TC_REQUIRE_KEY_EXCHANGE = FALSE means? There will not be any security enabled for the network?
I am expecting my coordinator centralized to be trust center and have install codes and dynamic key change functionality.
In reply to vikas k:
BDB_DEFAULT_TC_REQUIRE_KEY_EXCHANGE = FALSE means using Zigbee HA 1.2 security to encrypt network key with TC link key and don’t do TC link key exchange defined in Zigbee 3.0 spec.

Hi YK Chen,
So it is not possible to join the legacy SE devices to ZigBee 3.0 coordinator.
My customer has a requirement to join legacy SE devices to ZigBee 3.0 coordinator and gather information from SE devices.
As YK mentioned previously, Zigbee 3.0 is not backwards compatible with legacy SE. Your customer will need to consider updating their legacy solution or seek alternative devices to join the 3.0 network. Removing the security features necessary to allow SE devices to join is not an option in the SIMPLELINK-CC13X2-26X2-SDK.
They have smart meters based on SE profile.When you say "updating their solution" what does that mean ? upgrade to zigbee 3.0 ? Does TI support that ?
" seek alternative devices to join the 3.0 network" - Does this mean that use some other devices which support ZigBee 3.0 ?
it is not possible to join the legacy SE devices to ZigBee 3.0 coordinator.
My requirement is as below :
The coordinator is based on ZigBee 3.0 specification.The network will containZigBee3.0 coordinator, zigbee 3.0 routers, legacy HA and ZLL devices. The ZigBee 3.0 coordinator should be able to join zigbee3.0 routers ,legacy HA and ZLL devices.
Based on your repose above in order for legacy HA and ZLL device to join ZigBee 3.0 coordinator BDB_DEFAULT_TC_REQUIRE_KEY_EXCHANGE should be set to FALSE. Will there be an issue for joining another ZigBee 3.0 device to the coordinator while the macro is set to false ?
Also I would like to know if the ZigBee 3.0 coordinator support touch link commissioning for ZLL devices.
Other than coordinator all other devices used in the network will be off the shelf devices available in market.
