functions:

• XBee-API1.AT(command,value,function(re,data) {} )
• XBee-API1.TX(addr64,addr16,options,data,function(re,data) {} )
• XBee-API1.RX(function(data) {} )

xBee Frame Types implemented

• 08 => AT Command
• 88 => AT Command respond
• 10 => Transmit request
• 8B => Transmit Status
• 90 => RX Packet

Creating an xbee object

Initialize a serial object and pass it to the xbee object

Serial1.setup(38400,{rx:B7,tx:B6,bytesize:8,parity:none,stopbits:1});
myxbee=require('XBee-API1').connect(Serial1);

function XBee-API1.AT

###Call type: function XBee-API1.AT(command,value,function(re,data) {} )

Description:

Submits an AT Command.

Parameters:

command is the AT command without the "AT" prefix

value array of bytes. When empty the function reads the current value, otherwise it will be written

function the callback function. Called on timeout, or on success. on sucess, the value of 're' will be true and data contains an array with the returned data.

Example of the data array:

{
"cmd":"VR",
"status":0,
"data":[35,167]
}

Return:

No return value (undefined)

Examples:

Read out an AT parameter:

myxbee.AT('VR',[],function(re,data) {
    console.log(re);
    if (re===true) {
        console.log(data);
    }
});

Sets the NI to "MyBee":

value=new Uint8Array(5);
value.set('MyBee');
myxbee.AT('NI',value,function(re,data) {
    console.log(re);
    if (re===true) {
        console.log(data);
    }
});

function XBee-API1.TX

Call type:

function XBee-API1.TX(addr64,addr16,options,data,function(re,data) {} )

Description:

Sends data to another xBee radio.

Parameters:

addr64 64 Bit address addr16 16 Bit address

options See xBee API documentation, default 0x00

data Data to send

function the callback function. Called on timeout, or on success. on sucess, the value of 're' will be true and data contains an array with the returned data.

Example of the data array:

{
"destination":[0,0],
"retrycount":0,"delivery_status":0,"discovery_status":0
}

Return:

No return value (undefined)

Example:

    addr64=new Uint8Array(8);
    addr64.set([0x00,0x13,0xA2,0x00,0x40,0xA1,0xF1,0xE0]); // Destination 64 Bit address
    addr16=new Uint8Array(2);// Destination 16 bit address
    addr16.set([0x48,0xA0]);
    txdata=new Uint8Array(5);
    txdata.set('abcde');

    myxbee.TX(addr64,addr16,0,txdata,function(re,data) {
    console.log(re);
    if (re===true) {
        console.log(data);
      }
    });

function XBee-API1.RX

Call type:

function XBee-API1.RX(function(data) {} )

Description:

Register a callback function to receive data from other radios.

Parameters:

function the callback function. Called when data is received.

Example of the data array:

{
"addr64":new Uint8Array([0,19,162,0,64,161,241,224]),  // 64 Bit address of the sender radio
"addr16":new Uint8Array([72,160]),                     // 16 Bit address of the sender radio
"option":1,                                           // Options, see xBee API documentation
"data":new Uint8Array([70,114,105,101,110,100,115])   // The data itself
}

Return:

No return value (undefined)

Example:

    myxbee.RX(function(data) {
        console.log(data);
    });
