Part Number: CC2650
Other Parts Discussed in Thread: Z-STACK, CC2538

Hi All,

We want establish the secure Zigbee network by preconfiguring default key on each device in network.

We have following development environment 

  • IDE IAR 7.40,
  • TI Z-stack 1.2.2a home automation

We successfully enabled security on our ZigBee coordinator (cc2538) and tested with ubiqua protocol analyzer.

coordinator packets gets decrypted on ubiqua analyzer

As per ti Z-stack developer's guide version 1.00, we enable the SECURE set to one in f8wConfig.cfg.

we also set zgPreConfigKeys to TRUE option in ZGlobal.h  but packets are not get decrypted by ubiqua.

KEY values are same in end device, coordinator code and in ubiqua analyzer.

Please guide me for acheiving secure network using preconfigured keys.

is TC_LINKKEY_JOIN compiler flag  required for using precondigured key?

Regards,

Dhananjay Patil
