I use jn5169 as coordinator and routing. When the gateway accesses more than 30 sub devices, the latter one has already initiated association request when entering the network, and the routing device has also replied successfully. After updating to the coordinator, the coordinator does not send out the network key, resulting in the sub device unable to enter the network.
The coordinator uses jn-an-1216-zigbee-3-0-iot-control bridge, and the SDK version is jn-sw-4170 v1840. Sub equipment SDK:JN-SW-4168 v1620.
The attachment is the capture log and coordinator zpscfg file.
