Error: 13 when trying to start commissioner

[Glenyz]

Hi,

I am using the Thread: CLI example provided by Nordic's NCS samples. I have set up the commissioner before and it was working properly, but for some reason now when I try starting it again, I get the following error:

uart:$ *** Booting nRF Connect SDK 3758bcbfa5cd ***
ot dataset init new
Done
uart:$ ot dataset commit active
Done
uart:$ ot ifconfig up
Done
uart:$ ot thread start
Done
uart:$ ot commissioner start
Error 13: InvalidState
uart:$

I have not made any changes to the sample or the project configs. Does anyone know why it's giving me this error?

InvalidState error indicates that the device is not currently attached to a Thread network:

openthread/src/core/meshcop/commissioner.cpp

Line 283 in 7673194

VerifyOrExit(Get<Mle::MleRouter>().IsAttached(), error = kErrorInvalidState);

You can use the state CLI command to view the current state.

I see, I didn't give enough time for the device to attach to a Thread network. Now that I try it again it works fine. Thank you
