BASIC4PPC  COMPILER
PROGRAM  EXAMPLE:

Bluetooth  Serial  Port
Transmit  and  Receive

This program example will show you how transmit data
to and receive data from a microcontroller across a wireless bluetooth serial port connection using an embedded bluetooth hardware module.

The Pocket PC used in this example is an HP IPAQ H2210 PDA with:

     64 MB of system RAM
     32 MB of system flash ROM  ( Dated: 5/22/2003 )
     OS Version:  Windows CE 4.20
     Display Resolution:  240 horizontal pixels  by  320 vertical pixels
     Processor Type:  Intel PXA255
     Bluetooth
     1 SDIO Card Slot
     1 Compact Flash Card Slot
     Headset / Microphone Jack

This HP H2210 PDA was manufactured in 2003.  Any of the newer Pocket PCs with Bluetooth capability running the latest version of the Basic4ppc Compiler should be able to run this simple program example.

The embedded bluetooth hardware module used in this example is a BlueSmiRF module.  You can search the Internet and find a variety of embedded bluetooth module boards and fully packaged
plug-and-go bluetooth dongles.

The microcontroller used in this example is the: Athena.  The Athena micro is a PIC microcontroller that is pre-programmed with a BASIC Interpreter.  The Athena can be programmed easily in BASIC using the IDE software written to run on a Windows compatible desktop PC or laptop.

BASIC4PPC PROGRAM CODE LISTING : NO COMMENTS.

We need some way to send a wide variety of ASCII characters and character strings to a microcontroller so that we can test our embedded hardware designs.  In this example we
create a BASIC4PPC software application for the Pocket PC that can send just about any
ASCII character that we choose across a Bluetooth serial port link to a microcontroller.
By using such a program, we can experiment with a large number of ASCII character
"Commands" that can be processed by a microcontroller to perform a large number of
different functions.

This program allows us to send individual ASCII characters by pressing a button or
we can create ASCII character strings of any length that can be transmitted.  The TX
textbox window is used to create ASCII character strings by using the Pocket PC's
Soft Input Panel keyboard.  Once the string has been created we can send it by pressing
the "Send TX" button.  The "Send TX" button will transmit the character string that it
finds in the TX textbox window.

The RX textbox window will display all ASCII characters that is received by the Pocket
PC across the Bluetooth wireless link.  The Pocket PC can send ASCII characters to a
microcontrollers across the Bluetooth wireless link and a microcontroller can send
ASCII characters to the Pocket PC across the Bluetooth wireless link.

By connecting the TX line up to the RX line on the BlueSMiRF module, we can loop back
all of the characters that the BlueSMiRF receives from the Pocket PC and send these
characters back to the Pocket PC where they will be displayed in the RX textbox window.

This "loop back" configuration can be used to verify that the BASIC4PPC application is
sending the right ASCII character or string of characters to the microcontroller.

BlueSMiRF Bluetooth Module Configured in Loop Back Mode.
