Thread Commisioning don't change the Network Name and other parameters

[Nikhil Komalan]

Hello, 

I created a network using Border Router GUI with new parameters. I used external commissioning using Thread Mobile app to commission new thread devices. I managed to successfully commission my new devices  using app by passing eui64 and passphrase of joiner. But when i check the joiner Network Name and other parameters it's not changed as per the new network formation.

Only thing that got changed is PANID, Channel and Masterkey/NetworkKey. My joiner device also showed device joining success in terminal and i was able to ping my NCP device as well.

But i want t know why Network Name and some other parameters was not set as per new network. And will that effect my communication in anyway ? Because i was able to ping the border router successfully.

I would like to know what are the steps i should perform if i have to recommission the same device to another network. Suppose again i have changed the Network parameters in Border Router GUI and form the network. Will the external commissioning work with out flash erase  ???

Typically, the first step of recommissioning a device involves a factory reset. Does the issue still occur after performing a factory reset?

Network Name and Extended PAN ID are really information for the user and do not affect Thread connectivity.

okay i can apply factory reset on my thread devices. But how to apply the same to a NCP device ?

And so from my understanding panid,channel and masterkey should be same for all thread devices on the network  communicate.

When using `wpantund`, you can use the `wpanctl leave` command.

Correct.

Ok, thanks. 

Can you refer me any link from where I can get all wpantud commands.

[Jonathan Hui]

From the wpantund README.md:

If compiled with libreadline or libedit, wpanctl supports an convenient interactive console. All commands support online help: type help to get a list of supported commands, or add -h to a command to get help with that specific command.
