Well I’ve managed to get my core functioning again, by running partical doctor at home on my desk top, another windows 7 machine.
This machine is running CLI version 1.27 and node 4.2.2. When I checked which version of cli it is running it did prompt me:-
! A newer version (1.28.2) of particle-cli is available.
! Upgrade now by running: npm install -g particle-cli
So clearly I’m not going to update my desktop, unitl I can figure out why my laptop got all hissy-fitty with trying to upgrade the cli. All I did was run the suggested command line npm install -g particle-cli, and then it got nasty about the node version I was using, demanding node 4.4. after finally upgrading node to version 8 it started going wrong, forcing me in to uninstalling the cli both via the program manager, and becasue it was still there, the command line uninstall.
Thinking I was all clear I reinstalled via the program manager and now its really not playing ball. When I do get the core online via the laptop, it keeps goiong on and offline every 20 second or so.
As I have managed to get it working using an older install of my desktop surely it must be something in the laptop installation. And clearly casued by something uninstalling both the command line way and the program manager way failed to resolve.
Still scratching my head but I’ll try again tomorrow at work.
