How to update Babystar firmware


The present version of Babystar D-STAR hotspot is v. 1.04 and can be downloaded from the ON8JL website.

To update the hotspot with MacOS you can try and do what I did:

  1. Open the hotspot (screws on the underside)
  2. Attach the accompaning USB-cable to the three-pin serial-port
  3. Attach the USB-port and confirm that the port is created.
    Mine was called /dev/tty.usbserial-FTGXOC3V but milage may vary.
  4. Install Homebrew by following the instructions on the website
  5. Install Minicom with “brew install minicom”
  6. Install Ymodem (file transfer protocol) with “brew install lrzsz”
  7. Start Minicom with “minicom -s” which brings it into config-mode
  8. Under “File transfer protocols” change the filepath to Ymodem send files (under B) to “/usr/local/Cellar/lrzsz/0.12.20/bin/lsb -vv” and change recieve files (under E) to “/usr/local/Cellar/lrzsz/0.12.20/bin/lrb -vv”.
  9. When attached to the hotspot go to menu and choose Send files, then Ymodem and then choose the file.
