 00> rtt:~$

00> ot pollperiod
00> 5000
00>
00> Done

i try difference way to commissioning (use chip tool with command: ./chip-tool pairing ble-thread....--icd-registration true ) it change to LIT mode

00> rtt:~$
< ot pollperiod
00> ot pollperiod

Thanks alot for the documentation of chiptool, it very helpful.

I already add config:

CONFIG_CHIP_DEVICE_TYPE=21 (contact sensor)

but Homekit still doesn’t register as an ICD client.

Hi sangphan,

Susheel is out of office, and I will try to help in the meantime. I am however just a novice at Matter and don't have any Apple device to try the information I am referencing, so please bear with me.

Could you please commission the device with --icd-registration true and see if Homekit can register itself as an ICD client?

Hi Hiếu,

Thanks for reply, I aleady test:

- Fist, Commissioning device with Apple homekit (homepod mini, I see device have 2 fabric id, may be both Homepod and Iphone commissioning). But device dont witch to LIT

- Affter that, I share the  Apple code for chiptool and continue commisioning with chiptool (with --icd-registration true). Device can switch to LIT.

Hi sangphan,

What I mean is, is there no similar feature like --icd-registration true on Homekit?

Hi Hieu,

So it mean Apple dont support ICD device? If so, do you know any ecosystem support ICD device ?

I want to test ICD device with real ecosystem (like Apple, Google, Samsung....)
