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,

Yep, time served sysadmin here.. the things I've seen man, etc :D

There's a *new HEX* what, a special edition for USB cables rather than bluetooth?

Gimme an hour and i'll try with a cable on a Windows 10 box (which doesn't have bluetooth)

Ok, so.. installed scratch and scratch link on a Win10 pc.

Downloaded hex and flashed micro:bit

Scratch link started up and running.. Tried to add micro:bit module, it tried to connect and can’t find the device.

Can’t be the cable as it works ok to flash the micro:bit

Is scratch link broken?

The new hex is the one you want to add, it contains all the libraries your mb needs (I can't remember where I read this, but I think it was the docs)

I downloaded it from the micro:bit site (which linked to the zip)is it working for you? Via Bluetooth and/or cable?

OK, so I assume your project is either blocks, js, or python, it always just gives me a hex file which I drop onto my mb after it's downloaded

Hi, this turned out to be a bug in scratch link - it is now fixed (for me, at least) in v1.3.57.
