CCS/CC1352P: Device not responding to simple descriptor request over touchlink

Tool/software: Code Composer Studio

Hi,

I am using zr_sw_CC1352P_2_LAUNCHXL_tirtos_ccs example project from SimpleLink CC13x2 26x2 SDK-4.30.00.54 as router to form the network using commission from cli menu. And I have zr_light example code from same SimpleLink software. Here, I have configured zr_sw as BDB_TL_INITIATOR and zr_light as BDB_TL_TARGET. After select menu under config T.L. TRGT TIME to 15 sec in zr_light and zr_sw I select commission  cmd. I can see now, zr_light successfully join pair and control by zr_sw over touchlink.

But, I have now Phillips Hue Light instead of zr_light and I want to join,pair and control it from touchlink. But when I try to do so, Phillips light able to join network at same panid after exchanging Touchlink scan/responce and Network Join Req/Response. After then I can when zr_sw send request for simple descriptor phillips light not responding to anything. It stays on same panid and broadcasting some messages which is encrypted I can not see on sniffer logs of ubiqua. 

So, question here is what could be possible issue of this behavior?  

In, zr_sw I have set TOUCHLINK_KEY_INDEX as TOUCHLINK_KEY_INDEX_MASTER. Do I need to set have any MASTER KEYS? As, I can see there is TOUCHLINK_CERTIFICATION_ENC_KEY and TOUCHLINK_CERTIFICATION_LINK_LEY in bdb_interface.h 

Could not understand what could be possible issue for this. Kindly enlighten me. If MASTER KEYS is the reason behind this how can I get it?

Regards,

Dhaval

P.S :Snifferlogs is between zr_sw(E4:AF) form the network then 8E:71 mac is phillips switch. E4:AF initiate touchlink and phillips bulb joins network of panid FC64, 0002 is node addess of philiips bulb. From E4:AF select again commission so it sends out scan request and phillips reply with scan responce followed by Identify Request. Then I paired phillips switch  with phillips bulb (9C:22). and again using E4:AF triggers touchlink and philips bulb (9C:22) again join with zr_sw (E4:AF).
