Hi, This program allows you to transmit ASCII characters from your PDA to an external Bluetooth module. You can send one character at a time or you can create your own string of characters to be tranmitted. The program has buttons to support the individual transmission of both Upper case and Lower Case alphabetic characters ( A - Z ) and ( a - z ). The program has buttons to transmit the numeric characters ( 0 - 9 ). The program has buttons to transmit 24 special characters. You can create your own character strings by tapping the Stylus in the TX window to move the focus to the TX textbox and use the (S.I.P) Soft Input Panel keyboard to enter your text string, then press the "Send TX" button to transmit the entire string at once. I used the BlueSmiRF Bluetooth module in "Loop-Back" mode to test this program. "Loop-Back" mode is the TX line connected to the RX line, on the Bluetooth module. In the program "Bluetooth SPP", the Green textbox is the TX (transmit) window and the Yellow textbox is the RX (receive) window. The file "BSP3.JPG" is the screenshot view of the program. The file "Bluesp3.sbp" is the Basic4ppc source code for the program. The file "BlueSPPzip.zip" is the zipped up ARMV4 (.CAB) installation file.
