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.

Run the connection checker

 

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.

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

Manage the 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 the environment it detects (such as an Apple tablet using Safari or a Windows laptop using Chrome).

EdScratch will automatically use the suggested pulse type based on the environment it detects.

If the detected environment is not accurate, or if your programs are not downloading successfully, you can manually switch the compiler output type. Use the following information to select the output best suited to your device and try downloading a program to your Edison robot.

Set to Short pulse Set to Long pulse

 

Long pulse compiler output

This output type works well on devices with low output volume, including some tablets. If you are using a Mac computer, an iPad tablet or a Windows or Android tablet, the long pulse compiler output should work best for your device.

Short pulse compiler output

This output type works well on devices with sound enhancement software, including most Windows desktop and laptop computers. If you are using a Windows desktop or laptop computer, or a Chromebook, the short pulse compiler output should work best for your device.

Note: some Chromebooks, including some Dell Chromebooks, have low audio output but also have sound enhancements. If you are using a Chromebook with the short pulse compiler output and your program downloads are failing, switch to the long pulse option. If the long pulse option also fails, you will need to manually disable the sound enhancements on your device. Once these are disabled, use the long pulse output option.
