PearlBlue connects the radio serial port to a physical UART that can be easily interfaced to any embedded microcontroller, PDA, or computer.
Additionally, PearlBlue offers six general purpose I/O lines.
The tiny 1.25 x 1.1in PearlBlue can act as master or slave and implements a wireless RS232 link between computers, equipment, smart phones, and other Bluetooth devices.
PearlBlue may also be used as an RS232-to-Bluetooth configurable dongle with advanced capabilities such as: initiate a connection, wait for connection, search/identify (name and class of device), define name and CoD, security with configurable PIN, directly control six I/O lines etc.
PearlBlue is OS and hardware independent and is intended to give Bluetooth capability to embedded instruments, industrial controls, ambient monitors, medical instruments etc.
Bluetooth wireless protocol enables high-speed data transfer with portable devices such as handheld computers, phones, data-collection devices at low cost for up to 100m.
Radio power is 14dBm at a carrier frequency of 2.4GHz.
Power supply is 3.3V at 110mA maximum.
Operating temperature range is -40 to +70C.
An accessory RS232 board is also available ($99) with sockets for a PearlBlue module and a 3.3V regulator and is useful for quick PC connection.
Designed in Spain by emxys, PearlBlue is available now at US $99.00 (one-off) from stock at Saelig.
