Downloading BlueBasic 1.0 for Mac from the developer's website was possible when we last checked. We cannot confirm if there is a free download of this app available. We recommend checking the downloaded files with any free antivirus. The program relates to System Tools. This free Mac app was originally developed by Tim.
From the developer:
BlueBasic is the console application to connect to the Blue BASIC interpreter running on CC2540 and CC2541 Bluetooth LE chips. This project contains a BASIC interpreter which can be flashed onto a CC2540 or CC2541 Bluetooth module. Once installed, simple use the Bluetooth Console tool to connect and start coding on the device using good old BASIC.
