You read the string character at a time, until you get some sort of marker that indicates the end of the string (newline, space, etc.).

In terms of sending more than 1 character from the phone, it depends on your bluetooth app in the phone. Some can be configured to send more than one character, some can't. The app Bluetooth Controller, for example can be configured to send different text for the nine buttons that are configured on the screen: https://play.google.com/store/apps/details?id=apps.BT&hl=en
