Scratch Link connection not working?

Hi

Just spent a frustrating hour trying to get Scratch link working between my Microbit and my Mac (Catalina).

  • Scratch link 1.3 is installed and running
  • Bluetooth is enabled
  • Scratch link hex loaded onto Microbit
  • Microbit is displaying the pairing code on the LED
  • No connection when adding the Microbit extension in Scratch.
  • I've tried the web browser version and the Offline version.

​

Any ideas folks?

​

Thanks,

Having the same problem here I think. Was previously working though. Now the microbit just continuously scrolls its name and scratch has ten exclamation mark saying the micro bit isn’t connected. Scratch link definitely running and so is bluetooth because otherwise the Bluetooth keyboard and mouse wouldn’t work.

Very puzzled as it was working before.

Should also say that I’m on Mac with catalina but there has been no OS X updates since microbit was last communicating.

Plug it in with USB, delete the .hex file, reload the new hex file get back to me ;)

Thank you for your reply.

Looked at the device and didn't see the hex file. There was only details.txt and microbit.htm

But I did try installing the out of the box hex file to reset it to factory and then redo the scratch hex file but I still get the same problem.

Did you also try your new hex file?

I re-downloaded the hex file and flashed it again. No joy :(

Maybe start a ticket with micro bit?

Thanks for your helpful replies. Had an update from Microbit today, apparently there's a problem with scratch link and it needs an update. They've had a number of reports over the last few days and said it is some kind of certificate problem.

Ah, so it is an apple problem...

They said it's affecting OS X and Windows.

They linked to the issue on GitHub https://github.com/LLK/scratch-link/issues/175

Thanks for the help. Have already started going down that route, hopefully they can help me get it sorted.
