POCSAG library and demo application for Si4432-based ISM modules
It consists of:
-
A library called "Pocsag", the code to create an alpha-numeric pocsag-message
-
Two demo applications to send pocsag-messages using Si4432-based RF-modules. One designed for use on ISM-band frequencies (433/434, 466+, 863-870 Mhz) and a "ham" version using 430-440 Mhz.
RF Transceiver: Si4432
Board: Arduino
(of your choice, 328P recommended)
Connection: SPI
Copy the library folder contents (Pocsag) to your Arduino library folder.
Building also requires a modified "RadioHead" arduino library: https://github.com/milaq/RadioHead
Use the middle part of the "ID-Nr." as address. The frequency is also usually printed on the back. Data rate is 1200.
Keep in mind that many Si4432 modules have quite a bit of frequency shift. Two of mine deviate +16KHz.
