Hello,
I am trying to get access to the Bluetooth Bee individual ports, because I am trying to connect those pins to the external interrupts of my arduino.
I want to send a command (from my laptop for example) through bluetooth to the arduino. And depending on the info I send, I want the Bluetooth Bee pins to activate the external interrupt on the arduino.
I was trying commands such as “\r\n+PIO3=1\r\n” to set that pin high (and connected to one external interrupt on my arduino) but that does not work. And I cannot find proper documentation online for this specific module that would tell me how to do this task.
paired your Bluetooth Bee to computer Bluetooth , used Bluetooth Serial software send data to your Bluetooth Bee.
2.connected your Bluetooth Bee to Arduino , read the data from Bluetooth Bee .
3.Arduino programing , analyzed data then do PIO control.
From what I can see, the data sent to your bluetooth bee will arrive in the serial buffer (or software serial buffer) of the Arduino. There are 4 documented PIO’s that you can access from your Arduino, but they aren’t going to be useful to you in a general sense.
PIO0 is used to send the Bee the command to disconnect
PIO1 can be monitored to find if the bee is connected or not
PIO11 & PIO10 are status LEDs by default
Is there a reason this needs to be interrupt driven? If your Arduino isn’t doing anything else, this could be solved with something like this:
void loop() {
while(!Serial.available()); // do nothing until there's something received from Bluetooth bee on pins 0&1 of Arduino
switch (Serial.read()) {
case 0: // 0 received by bluetooth
// do something
break;
case 1: // 1 received by bluetooth
// do something different
break;
case 2: // 2 received by bluetooth
// do something else
break;
default: // something unexpected and unknown received
// deal with exceptions
break;
}
}(if your bee is on a different pair of pins, you’ll need to use SoftwareSerial…but same concept applies).
If your Arduino will be busy doing other things, perhaps have it routinely check to see if Serial.available() > 0 every half second (say) to act on these bluetooth commands will do the job?
