Matter Binding after disconnecting OTBR

[jayveer]

I am working on Matter binding between two matter enabled thread devices where i have flashed the light bulb code in EVBT840 and light switch in nrf52840 kit

I am using Raspberry pi 4B as OTBR and commissioning is done using chip tool in linux pc. After commissioning both the devices in thread network and matter binding is done between both the device is done where when i press the switch in matter switch the matter bulb glows. So after the matter binding between both the matter devices when i disconnect the OTBR the communication between them till remain for around 2 mins where without OTBR i can control bulb with switch but after that the connection breaks.

So once commissioned and matter binded ,then removing the OTBR should the connection between them still remain or there is issue with my ecosystem ?

Hi Jayveer,

Sorry for the late reply, we are understaffing due to summer vacation now.

Judging by the attached logs, the light bulb did become the leader and the network was recreated, so from Thread perspective everything works as expected. But still, Matter needs SRP server to make the communication between two nodes possible. In this setup it's OTBR which acts as SRP server, so once it's gone from the network, the nodes cannot talk to each other utilizing Matter interactions anymore (although should be able to do that using raw Thread networking).

Best regards,

Charlie

Hi Charlie ,

i understood what you are trying to convey me.

But now what changes or what should i do to make the system work after disconnecting the OTBR ?
