Bluetooth to Yaesu FT857

PLAYING AROUND WITH BLUETOOTH

Something i have been wanting to try out is Ham Radio Deluxe, the problem is you need some kind of serial connection between the PC and RIG for it to work. I am not a great fan of connecting RIGS up directly to PC, so i decided to see what i could find on the internet to create a wireless connection from my Laptop to my RIG.

I found this Bluetooth device on the internet and ordered one, looks like it would do exactly what i want.

Specifications as follows

Spec

● Bluetooth protocal:  Bluetooth Specification v2.0+EDR

● Frequency:  2.4GHz ISM band

● Modulation:  GFSK(Gaussian Frequency Shift Keying)

● Emission power:  ≤4dBm, Class 2

● Sensitivity:  ≤-84dBm at 0.1% BER

● Speed: Asynchronous:  2.1Mbps(Max) / 160 kbps, Synchronous: 1Mbps/1Mbps

● Security:  Authentication and encryption

● Profiles:  Bluetooth serial port

● Power supply: +3.3VDC 50mA

● Working temperature: -20 ~ +75 Centigrade

● Dimension: 26.9mm x 13mm x 2.2 mm

Very simple to setup , no programming etc to do, all this thing needs is 3.3v and then serial RX/TX tot he CAT converter on the back of the RIG.

The RIG i used is the Yaesu FT-897D which has 13.8 Volts on the CAT connector as well, which very nice and convenient.

Picture of the RIG i use.

This is what my unit looks like below  to the right of the picture is the 8 pin male connector going to the CAT port on the RIG and on the left is the small box with blue tooth module inside and 3.3 volt regulator. I have a high bright LED which shows when the module is paired with another device. When the LED is flashing then it is waiting to pair with another device, when the LED stops flashing this shows that the unit is paired with another device.

Below is the pin outs of the CAT port on the back of the RIG

The schematic I followed
