My project displays axis data from the MPU 6050 to the serial monitor but the app doesn't see the HC-05 Bluetooth module I'm using instead of an HC-06. The phone sees it and I tried renaming it on the phone to HC-06.
Can anybody help me?
Before working with the actual application make sure your hardware is working properly you can do this by either using a bluetoth terminal application on android to check if you are geting anything from the hardware via BT. Or you can also upload a simple led control program to check if the hardware and connections are fine
OK, I now have an HC-05 and an HC-06.
I pair the HC-05 and see it on my S8 Bluetooth as "DSD TECH HC-05", not simply "HC-05".
I guess that might be why the inclinometer program will not see it.
I have the circuit running and the Arduino program on my laptop showing pitch, roll, yaw, temp info scrolling on the ftdi terminal window.
I found a bluetooth terminal program and run it on the S8 paired with the HC-05. Set to ASCII it looks like gibberish but HEX seems to produce data that changes if I move the board various ways. Numbers and letters scroll up.
I'm not sure if I should see the data the same as the laptop over the FTDI terminal window.
I'm stumbling along the best I can which means I'm learning, so that's good.
I'm supposing I'm going to have to figure put how to get the name changed to HC-05 with AT command mode.

Thats off, normally the chip from manufacturers will read "HC-05".

Exactly you have to change the name using AT mode of edit the android application sketch using processing. The former one should be easier.

Hi Pete,
The android application is programed only to connect with devices named as "HC-05". If you are having a HC-06 then there are two thing that you can do to make it work.
Renaming Bluetooth module:
Yes, renaming the Bluetooth module will work but you cant do it form your phone. The HC-06 has to operatign modes, you have to get into the command mode and use AT commands to rename the Bluetooth module.
Changing the processing sketch:
Other option would be to change the code, find the name "HC-05" in the code and simply replace it with HC-06. This will make the application to connect to any device that has the name HC-06. But you should set up the Processing android mode in your computer to be able to compile and upload the program.
If you are in a hurry the easiest way it to get a HC-05 itself, I think you can easily fin one in your hardware store.
