HC-05 Bluetooth module settings in Linux using cutecom

By default the Bluetooth module HC-05 sets baud for 38400, data bits 8, Stop bits 1

All schematics of this Bluetooth module can be found At:http://pan.baidu.com/s/1o6binds

I used a usb-> TTL USB module connecting to the Bluetooth module.

Rx--Tx on Bluetooth module

Tx-Rx on Bluetooth module

5v, VCC

GND, GND

Getting in command line

Hold the key on the Bluetooth module when powering it on,

Then connect to serial ports on Linux using cutecom

IMPORTANT:

TRY: cr,lf line End

OR there would be is Error (0)

Set Serial port baud rate

at+uart=57600,1,0

Baud rate, Stop bits, even check, (the AT commands Doc provided above in Chinese are wrong. This command is the correct. I verified! )

Why 57600? Because the Tele transport module of drone Flight controller board APM 2.6 is going to need this baud rate.: Http://ardupi Lot.org/copter/docs/common-3dr-radio-advanced-configuration-and-technical-information.html

This works with 3DR Radio firmware version 1.7-1.9 by default.

Set the Bluetooth module broadcasting name

At+name= ' Tele '

Check version

At+version?

Try the Module:phone <-> Bluetooth <-> PC

Use a app called "Bluetooth Terminal HC-05" to connect to the Working Bluetooth module.

Find the Bluetooth module named Tele and input password 1234

(By default password is 0000 or 1234)

Open app "Bluetooth Terminal HC-05" Select CR(carriage Return), LF (line Feed).

Connect the Bluetooth module with the Usb->ttl dongle to PC and power it on normally.

Use cutecom connect to/dev/ttyusb0, Baud rate:57600, Data bits 8, Stop bits 1.

Send something from the phone to the PC, then from the PC to phone. It works like a charm!

Would show how to set the Bluetooth module with 3DR Radio 433Hz transmitter in next blog.
