thankyou for your information
i already try to modified the app and it make a good one.. but i have any problems now, not for the buttons..
if we use the bluetooth for communicate between android and arduino, first me must pair with arduino bluetooth and then we can control the arduino using android by bluetooth. the problem is, how to change the name of bluetooth of arduino and change the pairing code from android? as usual, if we can change the bluetooth name and pairing code of the arduino, we just change in the code of arduino, like this command : ("\r\n+STNA=BluetoothName\r\n");
but how to change bluetooth name from android not from the code of arduino? Thankyou.. i need your help, please
Hey sorry for the late reply to this. That is definitely a good question. I haven't bothered to go deep into this because I didn't need it, but it's something you will need if you want to build something more than a prototype. Here is a link
which allows you to change the name of the device. You can set it up so that the device disconnects when you do this, then programs it and then opens it for connection again.
Your app will also need to re-scan for available bluetooth devices. Might be a bit more involved. You can find more search results by searching for "linvor AT commands"
I am trying to draw graphs in android mobile out of data from accelerometer via bluetooth module,can you help me out with the graph part in android phone from the data that i have received from this app.
Sorry, I won't be able to help you with graphs on the Android since I haven't worked with them. But there are several results on Google and Stack Overflow
which help with this.
Also here's a link
that someone who used the app mailed me. It's an ECG scanner that uses Bluetooth, I'm impressed
