I’m certain this is a fairly common task that people employ Then, store the value in a variable - which one depends on the name token (use strcmp() to detect a match). Then, use “,” as the delimiter to get the value as a string (“20000”) and atoi() to convert the string to a number, 20000.

Use “=” as the delimiter to get the ExposureLength name. Where it says “Process the packet”, you can then use strtok() to get the bits from the array.

data has been read OR because an end of We are here either because all pending serial Read all serial data available, as fast as possible Then, you can use code like this to get the serial data into an array: #define SOP '' Your phone should be sending something like Then I modified the code so that my phone would send over the camera parameters and those would show up in the serial window. Then, regardless of whether or not there is serial data available: val = Serial.read() // read it and store it in 'val' If there is data available to read, do nothing. I am a complete newb with Arduino, and I'm certain this is a fairly common task that people employ.I've read through 'Getting Started With Arduino' and 'Beginning Arduino' and can't find anything specific. So I guess my question is - how do I get the Arduino to read and store those values (the #s - ie the ExposureLength=20000) in the loop? Do I need to declare 'ExposureLength' as a char and then somehow get the serial to read it's value (20000) and store it somewhere so the loop can read it? If( val = '1' ) // if '1' was received led 13 onĭigitalWrite(ledpin = 13, HIGH) // turn ON pin 13 on If( val = '0' ) // if '0' was received led 13 is switched offĭigitalWrite(ledpin, LOW) // turn Off pin 13 off Val = Serial.read() // read it and store it in 'val' If( Serial.available() ) // if data is available to read Serial.begin(115200) // start serial communication at 115200bps PinMode(ledpin = 13, OUTPUT) // pin 13 (on-board LED) as OUTPUT Int ledpin = 2 // LED connected to pin 2 (on-board LED)

I used this code ('bluetooth_LED_example') as a test to get the Arduino to turn on/off the LED when a 0 or 1 was sent via my Android phone.Ĭhar val // variable to receive data from the serial port Thanks alot for reading this! Any help is greatly appreciated.Īlternatively, If I could send the command from a fourth Arduino (a Mega) to the other three, that would be even better.Thanks for the reply.

Right now, each bluetooth connects to my computer via an individual COM port, and I have no how to set up a port that sends the message to all three bluetooth devices at the same time. However, I have no clue how to do the broadcasting. Is this the best way to do things? i am seeking for the commands to be parsed (relatively) at the same time, so I am thinking that this is the most effective way to simultaneously talk to 3 different bluetooth connected devices. ' The Arduino will parse the string, pick out the parameters that correspond to its ID, and use those parameters in its program. The string will have instructions for each arduino in the format ' |.

I am using the bluetooth mate gold from sparkfun and arduino pro minis. I am seeking to simultaneously send the same string over serial from my computer to multiple arduino components connected to the computer via bluetooth.
