Burger Pager

Note

This is an external app and must be present on the SD card in the APPS/ folder.

Burger Pager transmits FSK paging signals compatible with restaurant coaster pager systems. It allows sending a page to a specific pager unit by address, or scanning through a range of addresses automatically.

The default frequency is 433.920 MHz. Actual pager system frequencies vary by hardware — adjust the frequency field to match the target system before transmitting.

Settings

• Data (16 hex digits): The full 8-byte payload to transmit. The lower 16 bits (last 4 hex digits) represent the pager address. Default value: 44013B30303034BC.
• Scan (checkbox): When enabled, the app increments the pager address by 1 after each successful transmission and immediately retransmits, stepping through addresses continuously. When disabled, the frame is transmitted once and stops.

Frame Format

Each transmission consists of a fixed 19-byte FSK frame:

Bytes	Content
0–7	Preamble: 55 55 55 55 55 55 55 55
8–9	Sync word: 2D D4
10	Data length: 08
11–18	Data payload (8 bytes, from the Data field)

Modulation is FSK with a deviation of 5 kHz. Each frame is transmitted 32 times per press.
