The M5 doesn’t have an ethernet port, but we can simulate IP connection by giving the device wifi credentials. The device will start up advertising as a commissionable device.
Compile the device image as follows
Demo->Device Type = <as required> Component config-> Chip Device Layer -> WiFi Station Options - set up ssid and password
gn gen out/debug ninja -C out/debug
These devices start in commissioning mode if they do not have stored Matter credentials. Linux devices store credentials in the /tmp directory, so to re-commission the device from scratch, remove the chip_* files from /tmp.
There are two ways to connect via IP:
Discover then connect ip
discover -all
or
discover -qr “[qrcode]”
then
connect -ip <address from above> <setup pin code> [<node id>]
It is no longer necessary to run resolve after connect - this is done as part of the commissioning process
Connect using the QR code
connect -qr “[qr code]”
This will discover, connect over IP with the code from the QR and resolve.
You can connect using chip-tool either using the setup codes or by discovering the device on the network using one of the mDNS sub types. To get a list of the available options run
chip-tool pairing
For example, to discover, connect and commission using the long discriminator
chip-tool pairing onnetwork-long <nodeid> <setuppincode> <long-discriminator>
where the node id is set to a value of your choice (used to id devices for future communication), and the setup pin code and long discriminator are set by the device and are normally logged at startup.
