thank u so much. this very great but i dont have Ardoino and i shoud use it with AVR controler.
con you put program with codVision or basic (bascom Avr) to help me.
please help me if you can.

I can connect to the HC-05/06 with the Android. I’m unable to connect to the HC-05 through Tera Term and send AT commands. I’ve verified that the correct com port is selected in Tera Term setup. Any help is appreciated.

Hi Tom, you need to try and isolate the issue. Can you upload sketches if you disconnect the BT module from the Arduino? This error can be caused by a number of things, so it is hard to pinpoint the problem without more info.

When I run the Bluetooth sketch I get the following errors:

avrdude: stk500_getsync() attempt 8 of 10: not in sync: resp=0x00
avrdude: stk500_getsync() attempt 9 of 10: not in sync: resp=0x00
avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0x00

Your help is very much appreciated.

I ended up connecting the bluetooth device to the 3.3v on my arduino and it worked flawlessly. I never heard about the android app, and that was really awesome. Thanks again for taking the time to write this.

But even when I switch back to hardware Rx and Tx pin and observe the output long enough I would see similar error, or “noise” I guess. So this is, I think, an error somewhere in the analog part of my circuit. Just for some reason this error happen more often when I connect my JY-MCU into pin 2 and 4, use SoftwareSerial lib, and power my board with USB cable.

Yes, Stan. Supposedly :). Supposedly I use a simple voltage divider to convert the resistance of a sensor into voltage. But in this case I just short circuit the sensor so supposedly the voltage between two leg of the “sensor” should be 0. But interestingly it sometimes has some error. Today I notice that even using battery I would have some similar error sometimes, but the error rate when using USB as power source seems to be a lot more. Anyway, this error probably has nothing to do with your configuration.

Interesting… Are you reading a sensor value of some sorts?
