Product Name: 2x RS232 TTL UART Wireless Transceiver Module for Arduino DUE MEGA2560 3DR Radio
    
Module No.: TB394*2
 
 
 
Packing list:
2 pcs 2.4G RS232(TTL Lever) Wireless Transceiver Module;
2 pcs 2.4G IPEX Antenna
TB394_1
 
 
 
 
 
 
   
 
Overview:
   
TB387 is based on 2.4GHz frequency band wireless transparent data-transmission module.
Module supports most basic AT commands: baud rate, ID number, frequency settings and inquiries; factory settings; version information.
When the module is in AT module, users can use serial-port to issue AT commands to set the module's parameters.
When the module is in transparent data transfer mode, the user transmit data, frame number data module, add packaged rowcount, and then automatically transmit , at reliable range, the module will automatically re-transmit data to ensure successful transmission.

ARDUINO Serial data Transceiver:
 
 
Copy the following code:
//----------------------------------------------------------------------//
 
// Pin 13 has an LED connected on most Arduino boards.
int led = 13;
 
String comdata = "";
 
void setup()
{
// initialize the digital pin as an output.
pinMode(led, OUTPUT);
Serial.begin(9600);
Serial.println("Hello, I am Arduino!");
}
 
//Serial data transceiver
void loop()
{
while (Serial.available() > 0)
{
digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level)
comdata += char(Serial.read());
delay(2);
}
 
if (comdata.length() > 0)
{
Serial.println(comdata);
comdata = "";
}
 
digitalWrite(led, LOW); // turn the LED off by making the voltage LOW
}
 //----------------------------------------------------------------------//
