When the OTBR is rebooted after the Matter enddevice is paired with the OTBR, the chip tool command is not transmitted.

[classic037]

Hi

I am currently working on a Matter project.

I configured OTBR with Raspberry Pi, completed pairing with nRF52840 board (Light bulb), and confirmed that Light on/off works (use to chiptool command).

However, after rebooting the OTBR, the Chip tool light on/off command is not delivered to the Enddevice.

I checked the topology of Otbr web and found it was still connecting.

When Otbr is rebooted, the n52840 board log is also output as shown below.

After enddevice and Otbr are paired, if Otbr is rebooted, do I have to unconditionally pair again?

When tested using the Chip tool Android app, it was confirmed that the on/off command was delivered to the enddevice without re-pairing even if otbr was rebooted.

After pairing enddevcie and Otbr, even if Otbr reboots, please guide how to transfer to enddevice with chip tool command without re-pairing process.

Thank you

Thank you

Thank you very much!

Changing the tmp settings according to your guide solved the problem.

I agree with you. I think it's right to modify the chip-tool not to save the settings to tmp.

Can you guide me to save to a different path in chip-tool?

Thank you!

[Jørgen Holmefjord]

As far as I can see, the lines linked in my previous reply is the only place where the configs are stored in /tmp. Did you try to change these lines and rebuild chip-tool from the modified sources?

[classic037]

hi  Jørgen Holmefjord

I try edit the chip tool source and test it. I will share the results soon

hi  Jørgen Holmefjord

Do you know how to build in aarch64 format when building CHIP TOOL?

[Jørgen Holmefjord]

Did you try the instructions in the documentation? It mentions aarch64, so I would assume it would build for this architecture if you build it on the Raspberry Pi.
