Users can often help each other and not rely on your staff.
I am trying to join a sample/matter_light_bulb sample to a newly formed Matter network.
The problem I describe below might be able to be solved by the user community.
I hate to keep bothering your support staff.
--------
After getting the BLE and Thread samples working I tried to move on to the Matter demos.
I created and configured the OTBR and pulled its pskc credential. Does a thread need to be created first??
pi@otbr:~ $ sudo ot-ctl
dataset active -x
0e080000000000010000000300000e35060004001fffe002089cc49a9d067f70520708fdb36a43005d307305108b3d8982714220c637e513253a515ed9030f4f70656e5468726561642d32326166010222af04105f71e038e9fd24e1bdc8dbaf52deb52b0c0402a0fff8
Done
I compiled the Matter/CHIP Python tool on the same pi as the OTBR and ran the commands.
