Wireless UART

5.1.1 General Information

Free2move’s Wireless UART (WU) firmware is intended to replace the cable(s) connecting portable and/or

fixed electronic devices. Key features are robustness, high configurability, high security, low complexity and

low power.

The WU firmware is compliant with the Bluetooth Serial Port Profile (SPP) for setting up emulated serial

cable connections between connected devices. There is no additional need for drivers or an external host

with Bluetooth software when using the WU firmware.

Application

Wireless UART architecture

The WU application runs on top of an embedded Bluetooth v1.1 compliant stack, including protocols up to

the RFCOMM layer. Point-to-point connections are supported. This means that a unit running WU can be

either a master of one unit or participate in a piconet as a slave.

The WU firmware offers one asynchronous data channel and one synchronous voice channel, both

channels capable of full duplex transmission.

When a successful Bluetooth connection is established the data channel and the voice channel can be

used simultaneously or separately. All information sent/received at the data/voice interface of the WU unit is

exchanged transparently via Bluetooth with the connected remote device.

The WU unit is set to operate in a default mode that allows the user to communicate via the asynchronous

data channel over Bluetooth, as soon as a successful connection has been established. This can be

achieved without sending any configuration commands to the WU firmware. However, as long as there is

no Bluetooth connection established, it is possible to configure the WU firmware via commands (described

in detail in the separate Wireless UART datasheet) sent on the data interface.
