First, what is your purpose of sending text using bluetooth
Hello Utakarsha
You have not provided all the information I asked for.......
see Salman, I have a android circuit in proteus application and an arduino code in Arduino Ide. My project is to do " Voice Controlled home Automation". So if i speak "fan ON"v , the circuit should simulate according to the commands, thats why i want this app to work.
What exactly do you want Chris? Can you give an example as my English is a bit weak
Please see my post - I list the exact info needed.
Okay, i got it
Can you plz resolve this error ??
i will try
