Hi, I am stuck with this problem. I am trying to claim a core and have not been able to do so. The process ends up getting stuck with cyan LED blinking. I can not get the particle identify to work either(gets stuck forever) so can not do that online. Any help would be greatly appreciated. Thanks …

@sasi , the core needs to be breathing cyan in order to claim it. Blinking cyan means it is unable to connect to the :cloud:. Have you tried the steps i mentioned above?

Yes. I tired the steps. I meant breathing cyan earlier. I tried it on two cores and have the same problem. I see breathing cyan but can not get past this stage to where it shows the rainbow colors.

Do you see the cores listed using particle list?

Nope. I see a third one I had programmed successfully earlier.

Are the cores new? Place them in Listenin mode (blinking blue) and use the command particle serial identify to get the device id. Ensure that the core is breathing cyan and use particle device add device_id to claim the core.
