Hey guys, few months ago I bought a bluetooth module to play around with bluetooth. It is
(JY-MCU Bluetooth Wireless Serial Port Module for Arduino)
Just yesterday, I get to know that I can actually change the device name, baud rate, and also pair code for this device.
It's pretty simple to do this ! Believe it or not, it is simple !1. Materials required :
1. FTDI Programmer
2. Your bluetooth module
You can purchase one from HERE
Pretty cheap and affordable !
2. Connection :
Basically the connection is pretty simple, just cross the Tx and Rx for both devices and connect the VCC and GND as usual.
3. Software:
- Open up Arduino IDE
- Choose the correct COM Port for your FTDI programmer.
- Open the Serial Monitor
- To test whether it is communicating with each other, simply type "AT" on the monitor and ENTER. Then the serial monitor will display "OK"
- So to change the device properties, refer to the datasheet for more details on the command
AT Command Sheet DOWNLOAD
Try it out guys if you have one bluetooth module ! It's fun ! You can configure the device's name, pair code and baud rate !
If you bought a bluetooth module and it's not working, it might be the baud rate problem as experienced by one of my friends.
Thank you !
Enjoy !
