Datasheet

Switching Command/Data Mode via +++

On either side of the connection (via the Arduino Uno or in your mobile app), you can dynamically switch between command and data mode by

sending the "+++\n" string, as detailed in the +++ command summary (http://adafru.it/iCN).

If you start in data mode, you can send text for example, with "+++\nATI\n+++\n", which will cause the Bluefruit LE module to switch to command

mode, execute the ATI command, and then switch back to data mode.

The +++ command can be sent from either side, making it possible to execute commands from the mobile application as well as on the Bluefruit LE

side.
