Yes, you are completely correct.

The conclusion is that the Ember device will not be compatible with the ZBOSS stack.

Some explanation:

All devices in the same network needs to have the same stack profile to be compatible. So the fact that Ember has the network specific stack profile practically makes it incompatible with all non-Ember devices.

You can not rebuild the ZBOSS stack with the stack profile set as network specific. Even if you could you would still need to set all the parameters that Ember sets to make the two devices compatible.

Yeah I did. I know what is the problem but don't know how can I solve it.
The problem that the Ember device use the stack profile equal to "network specific" and the Nordic dongle use Zigbee PRO.
In the old nrf for zigbee and thread SDK there was Macro inside zb_config.h file that allow you when you enable it to connect to the Ember devices it's called `#define ZB_EMBER_GOLDEN_UNIT` (which in turn make the stack profile equal to network specific). I already enabled it and flashed the dongle with old firmware but still the same problem. In the last firmware version this value doesn't exist inside ZBOSS.
So this is the problem with stack profile but I don't know how to change it

Did you remember to set the device to be the Zigbee Coordinator before starting the Zigbee network?

Thanks for response
I've use the cli example for fast test and after I initialize the ZigBee stack and start it I run `bdb legacy enable` (I believe it is the same of the call you mentioned) but still I the device refused to join the network. I've checked the network traffic and no thing changed in the Beacon response. You can see it in the attached photo

Hello,

You can enable legacy support for the coordinator by adding a call to zb_bdb_set_legacy_device_support(1) after the ZBOSS stack is initialized.
