This serial Bluetooth adapter is similar to our Bluetooth version 2.1 adapters; the main difference is that this adapter is built around a Siliconlab BG22 processor which supports Bluetooth 5.2.
This adapter is a Bluetooth version 5.2 Low Energy (BLE) adapter, also commonly called Bluetooth Smart®. It will allow you to communicate with most serial RS232 devices using a Bluetooth Smart® enabled device such as an iPad/iPhone, Android, Windows tablet or any other Bluetooth Smart enabled device.
Notice that this adapter require a Bluetooth Smart® compatible device / application to be able to connect and transfer data with iOS, Android and Windows.
If you don't have a Bluetooth Smart® / Bluetooth BLE device then you can use one of our standard SPP (Serial Port Profile) v2.0 Bluetooth serial adapters instead.
Bluetooth Low Energy 4.0 or higher (BLE) / Bluetooth Smart® is supported by most newer tablets, phones, computers and other Bluetooth enabled devices, including the following devices: Android 4.3+, iPad 3+, iPhone 4S+ and iPad Mini.
The following operating systems support
Bluetooth Smart®: iOS 5 and later,
Windows Phone 8.1,
Windows 8 and later,
Android 4.3 and later, BlackBerry 10,
Linux 3.4 and later through BlueZ 5.0.
This Bluetooth Smart® wireless serial adapter has a maximum communication range of up to 160 feet (50m) and applications includes automation, home applications, automotive, laboratory, office use and many more, only your imagination is the limit.
This new version of the adapter also supports Modbus ASCII/RTU which makes it an ideal solution for many industrial applications.
The adapter can be configured as a central or peripheral (master or slave) device. It also has multiple other port parameters and functions such as baud rate, flow control, parity and data bits which can be configuredusing the free iOS/Android app, by DIP switches or through the COM port using AT commands and a terminal program.
