1: I want to achieve the same functionality as Raspberry Pi in other gateway devices.Do you provide the
gateway function source code on the Raspberry Pi running?
2: I use SPI to configure a node as bridge. and 4 anchr,1 tag. use the same panid.
tag and anchors use “si” display:
uwbmac: connected

How to configure bridge into the same network?

Whether the source code is officially available
