BlueSnap dongles are used to Bluetooth enable RS-232 devices. BlueSnap dongles are available in 9-pin male or female connections. These units are also available in battery powered (two AAA batteries - rechargeable or alkaline) or externally powered modules. BlueSnap units are compatible with Serial Port Profile (SPP), Human Interface Device (HID), and Bluetooth Low Energy (BLE) configurations. Note HID modules can send data to iOS devices but can not receive data from the iOS device.
