BlocklyProp Solo is an online visual programming tool for Propeller microcontroller boards.  It requires the BlocklyProp Launcher on your computer so your hardware can communicate with Solo.

Slow Downloads?

• If you're experiencing long delays at the start of every download to your board or bot, try turning off Bluetooth on your Win/Mac/Chromebook computer.  Recent versions of Chrome and ChromeOS changed the way Bluetooth devices are presented to software that communicate serially. On certain computers, this adds a significant delay at the start of the board or robot download process when BlocklyProp Launcher requests a list of available ports from the OS. Turning off the computer's Bluetooth hardware before programming these devices makes this interaction much faster.
