Matter : SRP update error: domain name or RRset is duplicated when using generated factory data.

abollaert

Hi,

I've been working on generating my own factory data (using the matter weather station application as an example). I'm using the generate_nrfconnect_chip_factory_data.py script to generate the factory data JSON, and then convert it to a hex file using generate_nrfconnect_chip_factory_data.py.

I also replaced the example device info provider with an internal flash based FactoryDataProvider, and all seems to work properly (I can see the device logging the data that was generated (serial number, discriminator and more)).

However, since using my own factory data, I'm having problems commissioning the device using HomeKit or Google Home (both worked before with the example info provider).

The error I'm getting is [DL]SRP update error: domain name or RRset is duplicated. A quick google doesn't seem to reveal anything however.

I suppose there must be something I'm missing here, but I thought the SRP name was generated based on the EUI64, which is unique per device?

Can anyone share some pointers as to what is causing this error?

Thanks and kind regards,

-Alex
