TME offers Bluetooth modules for wireless applications from Rayson, including the BTM-112, BTM-222 and BTM-330 modules.

The modules conform to the Bluetooth standard v.2.0 + EDR (2Mb/s and 3Mb/s), their carrier frequency amounts to 2,402-2,480GHz, and operating voltage is 3.3V.

The BTM-112 and BTM-330 modules’ RX sensitivity is -80dBm.

The modules provide communication over a distance of up to 10m.

The BTM-222 module features a receiver of -86dBm sensitivity and a transmitter of 18dBm maximum power (class one), which allows for wireless communication over a distance of up to 100m.

Control of the modules depends on the implemented protocol.

In BTM-112 and BTM-222 it is Serial Port Profile (SPP) with AT command sets.

With their use it is possible to easily establish a wireless link substituting for a standard RS232 connection.

AT command sets are not available in the BTM-330 module, as it utilises the HCI (host/controller interface) protocol.

The control of the module is realised by the use of the USB or UART interfaces.

Additionally, BTM-112 and BTM-222 modules provide the PCM interface for voice codec.

All modules are fitted for PCB mount.

Their dimensions are: 25 x 14.5 x 2.2mm (BTM-112); 28.5 x 15 x 2.8mm (BTM-222) and 14 x 12 x 2.2mm (BTM-330).

BTM-222 and BTM-330 modules meet the requirements of the RoHS directive.

Transfer Multisort Elektronik

The Transfer Multisort Elektronik Company was created in 1990 as a little shop run by the family and dedicated to sales of a wide assortment of electronic elements for service and small production purposes. Two years later, we took up the mail-order sale of components. We also started delivering catalogues providing information about products in our offer, which was the innovative practice in these times.

Now TME is the biggest electronic components distributor in central and eastern Europe. We supply several thousands of companies in more than 50 countries and we send almost 2,000 packages a day. Among offered products you will find goods of the majority of significant electronic components producers.

Our staff includes several dozen engineers specialised in the field of electronics and electromechanics, as well as automation consultants ready to support you.
