ZigBee 3.0 - connect up to 200 nodes

Discussion created by Jainil Shah on Apr 11, 2017

Hi All,

 

I am working on one customer based project. I need to connect 200 ZigBee devices in ZigBee network.

 

I am using JN-AN-1216 (JN-AN-1216-Zigbee-3-0-IoT-ControlBridge-v1004) application code and JN517x ZigBee 3.0 SDK (JN-SW-4270). As so far, I am able to accommodate 60 devices in network (within single hop) and it is working as expected.

 

After that I have changed JN5179 firmware (JN-AN-1216 ControlBridge application) by changing various table configuration (size) (and some changes on JN-AN-1216 application notes) to accommodate 65 devices in network. After this modification, I am able to add only 60 devices in network and not able to control those devices. I have connected all 60 devices in first hop (with Co-ordinator only). Please find memory usage details for this binary as below:-
 text       data      bss     dec      hex
179736   2557    28997  211290  3395a

 

so, only 0.5K RAM is left and may be EEPROM is overflow because remaining EEPROM sector is less than 4. Due to those reasons, I am not able to accommodate more than 60 devices in network.

 

Please help me to accommodate more devices in network within some hops.

 

If anyone have connected that much devices earlier, please mention table configuration for 200 ZigBee nodes.

 

Let me know if you have any questions or queries for the same.
