Overview

Dual-mode Bluetooth is a wireless module that allows bi-directional transparent data transfer between the TTL serial and Bluetooth devices. It is designed to be master/slave-in-one, also, it supports iBeacon. You can easily operate the module via AT commands, like: set baudrate, change broadcast name, and IO control, etc.

Features

• Dual-mode Bluetooth, completely compatible with iOS and/or Android devices
• Works as a full-duplex serial pipe after pairing, requires no Bluetooth protocol knowledge
• Fully configurable via AT commands
• XBee interface
• Comes with iOS and Android demo code, like: mobile robot remote control, data acquisition, device status monitoring, etc.
