Board manager type selection does not list "contributed

I am trying to add the Redbear lab blend board, and when I go to the board manager and select type, it does not list the contributed selection.

it only list:

All
Updatable
Arduino
Arduino Certified
Partner

How do I get it to list "Certified"

Have you added the Boards Manager URL for RedBear Labs boards to File > Preferences > Additional Boards Manager URLs?

Yes, I did add the URL as directed in the instructions

Do you see the the RedBearLab entry on the list when you have Type: All selected?

Which version of the Arduino IDE are you using?

Is this the Boards Manager URL you used: https://redbearlab.github.io/arduino/package_redbearlab_index.json

The URL listed is the one I used, and the IDE version is 1.67.

I can not see the REDBearLab entry under the "All Selected", but I do get an error message that says it can not find https://redbearlab.github.io/arduino/package_redbearlab_index.json when I enter the Boards manager, or click on the Types button.

It works for me with 1.6.7 and that URL so I think it's your firewall or something like that blocking Boards Manager from downloading from that URL. So if you can't use Boards Manager you will need to manually install the hardware files.

  • Download this file: https://github.com/RedBearLab/Blend/archive/master.zip
  • Inside the zip file is a folder Blend-master.zip/Blend-master/Arduino/hardware/blend copy the blend folder to the hardware folder that is in your sketchbook folder. If you don't know where your sketchbook folder is it's listed at File > Preferences > Sketchbook Location in the Arduino IDE.
  • Restart the Arduino IDE if it's running. Blend and Blend Micro boards should now appear in your Tools > Board menu.

There are some libraries that are needed to use the BLE. These are supposed to be installed via Library Manager as explained here: Blend/LibraryManager.pdf at master · RedBearLab/Blend · GitHub but you may also have trouble using Library Manager for the same reasons that Boards Manager didn't work. If this is the case and you need these libraries then let me know and I can help you manually install the libraries also.

You sure there's not any typo in the URL?

Could some sort of firewall software on your computer be blocking the IDE from accessing the internet?

If you're using Windows you might need to install the RBL driver to be able to upload to your board. The driver file is also in the file you downloaded to install the Blend board files. Follow the instructions in the driver section of GitHub - RedBearLab/Blend: Arduino-compatible boards (Blend and Blend Micro) with BLE (Atmega32u4 + nRF8001).
