Abstract
A detection apparatus for the pair mode of a wireless electronic device comprises a detector for external hanging state, a read-write interface of a nonvolatile memory, an interface controller, an automatic/hand-operated pair mode decision device, and an external interface unit. The detector for external hanging state and the read-write interface of a nonvolatile memory are both connected with the external interface unit, and receive information from the external interface unit to output the information to the automatic/hand-operated pair mode decision device. The automatic/hand-operated pair mode decision device determines the corresponding pair mode according to the output from the detector for external hanging state and the read-write interface of a nonvolatile memory, and inputs an order to the interface controller to change the type of the external interface unit. By using the detection apparatus, the determination of the automatic or hand-operated pair mode of the wireless electronic device is achieved, so the compatibility of automatic and hand-operated pair modes is realized, thereby facilitating the simplification of the complexity of the wireless electronic device, and improving the use convenience.
