Newbie problems - Sensebender GW + Arduino v1.8.2
I've ordered a Sensebender GW from ITEAD, and was just trying to prepare my laptop (MacOS) with the Arduino IDE...
- Downloaded Arduino IDE 1.8.2.
- Added "https://raw.githubusercontent.com/mysensors/ArduinoBoards/master/package_mysensors.org_index.json" to the board manager.
- Installed 'MySensors SAMD Boards' version 1.0.5 from the board manager.
But if I now try to select Sensebender Gateway as a board, Arduino complains "The current selected board needs the core 'arduino:arduino' that is not installed".
Would someone tell me what I've done wrong please?
