Your Spark service is waiting for the controller handshake

I normally manange to (fresh/new) install these things first time by being rigorous with the instructions but I’ve clearly got something wrong this time. A new install today on a Pi4 - I’m left with a blank Spark with a flashin blue light and:

Any ideas where I might start looking for errors?

Thanks, Andrew

Power cycle the Spark. If it doesn’t show six blocks on its screen, and you already flashed the firmware, you can run the bootloader.

brewblox-ctl particle -c flash-bootloader

We disabled wifi in brewblox-ctl for now. You can still set it in the UI - you’ll just need to connect to it once over USB.

I have no idea how you knew that from the little I said but that’s done the trick - all up and running…

Thanks very much,
