The Dual-mode Bluetooth to USB Module is a wireless system that allows bi-directional transparent data transfer between TTL serial and Bluetooth devices (including BLE). It is designed to be master/slave-in-one; also, it supports iBeacon. You can efficiently operate the module via AT commands, like set baud rate, change the broadcast name, and IO control, and more.
- 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
