Hi, please check weather the R12 is 10K(103). The manufacturer made a low-level mistake that the R12 is 1K(102) . The R12 should be 10K(103) otherwise the Xbee will not work.
Can you change the resistor by yourself ? We are really sorry about that ...
The following picture is the layout of the board, So please check it.

2013-05-29 08:52:00 Are you still experiencing the same problem with Ecoduino? jorgea

2013-04-30 10:43:46 Hi,
Thank you or your test codes, but they don't work. I caan't establish communication through the XBee.
I neither can't send AT commands to the XBee on the ecoduino : I put empty setup() and loop() functions in the ecoduino and then use terminal to send AT commands (as I do with my other arduino).
It seems having a problem with the XBee connection on the ecoduino

I have a couple of test codes. You can have a try.

Sender:
void setup()
{
Serial.begin(9600);
}
void loop()
{
Serial.print("wireless");
Serial.println();
delay(500);
}

Receiver:
void setup()
{
Serial1.begin(9600);
}
void loop()
{
if(Serial1.available()){
Serial.write(Serial1.read());
}
}

2013-04-17 23:41:55 Hi,
I understand that I have to use Serial1 to communicate with the Xbee and Serial for the USB. I tried that but it didn't work. Here is the program on the ecoduino :

Code: Select all

void setup()
{
  Serial1.begin(9600);
}

void loop()
{
  Serial1.print('H');
  delay(1000);
  Serial1.print('L');
  delay(1000);
}

And the program on my other arduino connected with USB :

Code: Select all

int incomingByte;      // a variable to read incoming serial data into

void setup() {
  // initialize serial communication:
  Serial.begin(9600);
}

void loop() {
  // see if there's incoming serial data:
  if (Serial.available() > 0) {
    // read the oldest byte in the serial buffer:
    incomingByte = Serial.read();
    Serial.println(incomingByte);
    
  }
}

I don't see any data on the Serial of this arduino. I tried to monitor the voltage of the Xbee on the ecoduino and the pins DIN and DOUT are about 0.8V which seems that data are not transmitted to the Xbee.

Hi, sorry for replay late.

Serial is if for communicating with PC. As you said , when you want to monitor the data with Arduino IDE ,you should use "Serial " not "Serial1".

But if you want to use Xbee to transmit data, you should use "Serial1" not "Serial"

Here is the details about serial of Leonardo:

Serial: 0 (RX) and 1 (TX). Used to receive (RX) and transmit (TX) TTL serial data using the ATmega32U4 hardware serial capability. Note that on the Leonardo, the Serial class refers to USB (CDC) communication; for TTL serial on pins 0 and 1, use the Serial1 class.

2013-04-13 13:28:36 Hi,
Thanks for your help.
I replaced Serial by Serial1 in my program on the ecoduino, but it doesn't work anymore. When I try to monitor the data with the serial monitor of Arduino IDE of my other arduino, nothing appears.
I have an ecoduino V1.0

The xbee socket is using the Serial1. So please modify the code a little bit (Serial -> Serial1) and test it again.

Hi everybody,
I have a problem using xbee with the ecoduino auto flower watering kit. I have a serie1 xbee with the default configuration. I use the following program on the ecoduino board :

Code: Select all

void setup()
{
  Serial.begin(9600);
}

void loop()
{
  Serial.print('H');
  delay(1000);
  Serial.print('L');
  delay(1000);
}
