Hey there,
i have some difficulties to connect my arduino with this bluetooth module:
http://www.seeedstudio.com/depot/serial-port-bluetooth-module-masterslave-p-572.html
I want to use it with my android phone via amarino, but my problems start right at the beginning.
The module is connected a bit nonprofessional on a breadboard, wired like:
module → arduino
GND → GND
3.3V → 3.3V
RX → 9
TX → 10
This is my sketch to set up BT module:
#include <SoftwareSerial.h>
SoftwareSerial bluetooth(9,10);
void setup(){
Serial.begin(38400);
Serial.flush();
bluetooth.begin(38400);
}
void loop(){
if(Serial.available()){
bluetooth.write(Serial.read());
}
if(bluetooth.available()){
Serial.write(bluetooth.read());
}
}
I tried some commands but mostly i got the same back, sometimes i got an “ERROR” back.
Now i noticed this in the datasheet: Low Power 1.8V Operation ,1.8 to 3.6V I/O
Is it possible that i destroyed the module?
Thank you for any help, i really need something like a tutorial :~
