commissioning failed

[flatsiedatsie]

I'm trying to commission a device (Tapo P125M mini). This is not on Home Assistant, but using the library in another project.

The process gets very far, with a lot of success messages, but then seemingly stumbles at the finish line:

}

Then there's a few more "does not look like a CHIP device." messages, and then a final error:

DEBUG:chip.BLE:Device REDACTED does not look like a CHIP device.
DEBUG:chip.BLE:Device REDACTED does not look like a CHIP device.
DEBUG:chip.BLE:Device REDACTED does not look like a CHIP device.

ERROR:chip.-:../src/platform/Linux/BLEManagerImpl.cpp:814: CHIP Error 0x00000032: Timeout at ../src/controller/SetUpCodePairer.cpp:299

To get to this point I had to use the Tapo Android app to connect the device to Wi-Fi first. It then temporarily becomes discoverable. Normally the discover process won't find it. Is that as expected?

do you have TP-Link certificates loaded?

[flatsiedatsie]

I don't know. :-D

• How can I find out?
• Where should I place them?

Is it /data/credentials/development/paa-root-certs ?

[flatsiedatsie]

I've managed to pair it!

For anyone finding this: the credentials/development/paa-root-certs directory has to be relative to the PWD - the working locaation of your script. This might not be the same as the location of the script.

It also seems important to really factory reset the device before a connection. Perhaps the device starts ignoring requests if too many are made, and the factory reset ... resets that.

Sorry to comment on an old issue, but where should I be getting the TP-Link certificates from? I'm not seeing any info when I search for the ppa-root-certs

OK, I see the URL here: https://github.com/project-chip/connectedhomeip/raw/master/credentials/development/paa-root-certs

What PWD/script are you talking about?
