Correct...IOIO Inventor is currently limited to these commands for Mit's App Inventor development environment.
http://doc.inex.co.th/ioio-board-command-code-on-app-inventor-for-ioio-inventor/ The last step For Full IOIO-OTG functionality, is a IOIO Inventor command to setup and control the sequencer. Rapid development of advanced robotic Apps without the need for Java coding is the goal.... I'll keep working on it...Thank you.
