XBee Adapter Kit questions

[grooove]

sorry if this is not the right place to post XBee Adapter Kit questions..

I purchased 2 XBee PRO modules, and now I am thinking in getting 2 XBee Adapter Kits

Does the adapter work with the Pro version?

Do I need to get the USB FTDI cable ? What is this cable for?

Is there any european reseller?


sorry if this is a stupid question

[adafruit]

the adapter works with pro and not-pro xbees. you'll have to look around european electronics stores for xbees since i dont know off hand the names of distributors
the FTDI cable allows you to talk to the xbee direct from your computer.

thnx :]

the adaptors are working in plenitude

is it possible if you (or someone) can help me with a handshake example?

Arduino # 1 has two potenciometers

Arduino # 1 sends value of the potenciometer 1

Arduino # 2 recieves value of the potenciometer 1

Arduino # 2 sends OK to Arduino # 1

Arduino # 1 recieves OK from Arduino # 2

Arduino # 1 sends value of potenciometer 2

Arduino # 2 recieves value of potenciometer 2

Arduino # 2 sends OK to Arduino # 1

Arduino # 1 sends value of potenciometer 1

and so on ...

Is this the right way?
I can conceive this pseudo code, but can´t translate it to real programming..
If someone can help me I would really appreciate.

after doing research on how to read 'byte' values and convert them to 'int', I came up to this solution.

sender arduino:

Code: Select all

int analogValue2, analogValue5;
int val2, val5;

void setup()
{
  // start serial port at 9600 bps:
  Serial.begin(9600);
}

void loop()
{
  // read analog input
  analogValue2 = analogRead(5);
  analogValue5 = analogRead(2);

  val2 = map(analogValue2, 0, 1023, 253, 0); //254 and 255 for SYNC
  val5 = map(analogValue5, 0, 1023, 253, 0);

  Serial.print(254, BYTE);  //SYNC char
  Serial.print(val2, BYTE);
  Serial.print(255, BYTE);  //SYNC char
  Serial.print(val5, BYTE);

  // pause for 100 milliseconds:
  delay(100);      //
}



reciever arduino:

Code: Select all

#include <AFSoftSerial.h>
AFSoftSerial mySerial =  AFSoftSerial(3, 2);

byte incomingByte;
byte sensor1, sensor2;

// - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
void setup() {
  Serial.begin(9600);         // connect to the serial port
  Serial.println("Goodnight moon!");

  // set the data rate for the SoftwareSerial port
  mySerial.begin(9600);
  mySerial.println("Hello, world?");

}

// - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
void loop() {
   
   if (mySerial.available()) {
      incomingByte = mySerial.read();

      Serial.println(int(incomingByte));

      if ((int(incomingByte) == 254)) {
        sensor1 = mySerial.read();
        Serial.print("Sensor 1 = ");
        Serial.println(int(sensor1));       
      }

      if ((int(incomingByte) == 255)) {
        sensor2 = mySerial.read();
        Serial.print("Sensor 2 = ");
        Serial.println(int(sensor2));             
      }
   
   }

}

Hello!

I have a quick question about the Xbee Adapter Kit: Can I use the FTDI Basic Breakout board from sparkfun to talk to the Xbee Adapter kit here? I'm sorry if the answer is obvious! (As I'm sure it will be once I've started playing with this stuff some) Thanks!

Here is the the FTDI Basic Breakout link: http://www.sparkfun.com/commerce/produc ... ts_id=8772

im pretty sure it doesn't work, despite the description saying its "ftdi cable compatible" its doesnt have the same pinout, I wish they'd fix it

[rchmc]

Thanks! I thought something was fishy. I'm guessing the RTS and DTR pins are quite different... Would it work if I connected the DTR pin on the Sparkfun FTDI Basic Breakout to the DTR pin on the Xbee Adapter Kit? (Please see my attached picture for the work-around idea I have). Thanks again for the advice. I'm sorry for my ignorance at this point as to what RTS and DTR in this interface :/

it -should- but there is no way for me to verify, sorry

I have the Sparkfun "FTDI" break-out boards that you mentioned, and some of these Xbee adapters on order (they should be here by the weekend).

Once I get everything, I will test out your workaround circuit and post my findings here.

[rchmc]

Cool, thanks! Good luck.

OK, I have the Adafruit Xbee adapters, a real FTDI cable, and sparkfun's FTDI basic breakout.

I ran a few simple tests using both devices, and got the same results with both! I was able to connect to the Xbee module using X-CTU program via ALL connection methods (even the SF Module which has DTR instead of CTS, and 3.3 instead of 5V). While connected I was able to read & update the Xbee firmware as well as send receive data to another Xbee device wirelessly.

Obviously these tests weren't enough to point out the fact that the interface's CTS line wasn't connected properly to the Xbee, or else it shouldn't have worked.

Does anyone know what type of test I should run to determine if re-routing the SparkFun Modules's DTR to the XBee DTR will work? (as pictured in the 2nd scenario in "rchmc"'s picture above.)

ok excellent! good to know it works!
