Hi, This program displays a simple 16 key keypad on your PDA. When you press one of the 16 keys a single character will be transmitted out the Bluetooth Serial Port connection. You must open the Bluetooth Serial Port connection first, before you start pressing keys. You can use your PDA as a wireless keypad and send characters to an external embedded Bluetooth module. The file "Rfkey1.JPG" is a screenshot of the program. The file "Rfkeypad.sbp" is the Basic4ppc source code for the program. The file "Rfkeypadzip.zip" is the zipped up ARMV4 (.CAB) installation file.
