I cross compiled obtr, but couldn't receive the message for the light bulb correctly.

[xjshiMax]

My testing method is to cross compile the openwrt version of OTBR on Ubuntu, then port it to the device and run it normally. The nanoleaf app thread can search for it, but it is grayed out. My OTBR also cannot receive the SRP message of the light board. I checked some information and said it may be a problem with the routing table, but I don't know how to configure it.

The output of neighbor table is empty, which indicates that there are no other devices attached to your OTBR.

I would first validate that Active Operational Dataset matches exactly what your other Thread devices are configured with.
