The Java APIs for Bluetooth is a Java ME specification for APIs that allow Java midlets to use Bluetooth on supporting devices. The specification was developed under the Java Community Process as JSR 82. The Specification, Reference Implementation, and TCK [1] are maintained at Motorola Open Source.

Java APIs described in the JSR-82 interface for following Bluetooth Protocols/Profiles:

  • SDAP - Service Discovery Application Profile
  • RFCOMM - Serial Cable Emulation Protocol
  • L2CAP - Logical Link Control and Adaptation Protocol
  • GOEP - Generic Object Exchange (OBEX) Profile

JSR 82 implementations for Java 2 Platform Standard Edition (J2SE) are also available.

Common Problems

When the Bluetooth Special Interest Group wrote the Bluetooth specification, they misinterpreted the requirement to reserve low ports for future use. Instead they chose to block all use of low ports. This means that any future standard service making use of the reserved ports will not work. The first example of such a service is HID. Bluetooth keyboards, mice and other input devices cannot connect to java programs running on bluetooth mobile phones because of this mistake. Some newer implementations ignore this part of the spec to allow such devices to function.
