The point of the commissioning procedure is for the device to obtain the masterkey from an existing network device to allow the new node to attach to the network using the obtained masterkey.

By adding the eui64 of the device to the commissioner, only the device with this identified can be commissioned to the network. It is also possible to start the commissioner with a * to allow any devices to be commissioned. The "J01NME" that is used in the tutorial is the shared secret that is entered on both commissioner and joiner. This prevents other devices from spoofing the eui64 of the device to become commissioned into the network, as it will not know the shared secret.

The network data is stored in flash after commissioning, you do not need to perform the commissioning after every reset.

I followed this tutorial https://codelabs.developers.google.com/codelabs/openthread-hardware/#8

in which commissioning the FTD joiner using eui64 command doesn't need to have same master key,

I repeatedly asked the same question and received the same answer,

It would be better if someone says exactly what happens after reset , if i commission the mesh as mentioned in above tutorial using eui64 command

The reason is due to covid , I just theoretically studied how to develop mesh using openthead cli to interface 30 nodes, I can't implement practically to see the results (Can't access the hardware as far now) and also time to complete the project is very less,

The OpenThread stack stores persistent network data automatically in flash. You should not need to recommission the device after a power failure/reboot. However, you need to make sure that the firmware does not use the default masterkey and on boot (most of our examples use autocommissioning and use default masterkey from OpenThread).

I am using eui64 commands to comission the mesh node, if power failure occurs at a node , when the node restarts , is it necessary to commission the node again or will it connect to mesh automatically??

Hi,

These commands will take down the Thread and IPv6 interfaces, so for the network, it may appear similar to a power failure of the device.

Best regards,
