title: USB-zigbee connection & programming
body: <p>I am sending ASCII character to USBport of laptop, need to give this ASCII as input to zigbee, which is to be used as a transmitter.How to accomplish this? what do i exactly need to use, USb to TTL dongle or xbee usb adapter board?</p>
  
  <p>I need to transmit ASCII character  using one zigbee and use another zigbee to receive the same i.e. i need to transmit and then receive the ASCII character using zigbee 2 zigbee. Then the output of receiving end zigbee is to be fed to microcontroller PIC16f628.
  do i need to program both the zigbee for communication?
  do i need to program receiving end zigbee to communicate with microcontroller?</p>
