HC-05 Bluetooth module settings in Linux using cutecom

Source: Internet
Author: User

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.
