Connectivity issues

To ensure that your program can be compiled and sent to the Edison robot, it is a good idea to check your connection with the EdScratch compiler.

Compiler output type

To be sent to the Edison robot, your program must be compiled by the EdScratch compiler. The EdScratch compiler can create two types of outputs and automatically chooses which type to create for you based on what it detects about your device.

If your programs are not downloading successfully, you can manually switch the compiler output type.

Need additional help? Please feel free to contact us.

Troubleshooting - Connection

If the test above has the result "NO SERVER FOUND" then a firewall may be blocking access to the compiler.

To rectify this, ask your network administrator to whitelist these addresses:

  • api.edisonrobotics.net
  • wavs.edisonrobotics.net
