Behavior of Moveslink from Suntoo troubles Arduino

Hi,

Just a post to mention a discovery I just made after months of misbehavior: The Suntoo Moveslink (GPS watch software) application on Mac (not sure on Windows) keeps opening usb-serial ports, and may interfere with your Arduino.

Proof:

  • I startup my Mac fresh, and let Moveslink start (it's a background service)
  • I unload Apple VCP drivers to enable FTDI drivers
  • I plug my Arduino via FTDI usb adapter
  • I run 'lsof | grep usb' and find that the Moveslink process has opened /dev/tty.USBSERIALxxx
  • Now, my Arduino software can no longer open the serial monitor, with message "port busy"
  • I can no longer program my Arduino

Solution: Close Moveslink when working on Arduino projects. Everything comes back.
Long term solution: I will open a support issue with Suntoo team to resolve this one

Hope this helps the few of us who run with a GPS watch AND play with Arduinos...

Hi,

I've jut got the same issue on El Capitan using a clone with ch340 chip. Closing Moveslink while using Arduino works fine for me too. I have recently updated Moveslink application, it looks like Suunto has not solved the problem.

Anyway, thanks for the help. :slight_smile:

Cheers.
