OOK Editor

OOK Editor is a free-form On-Off Keying transmitter. Unlike the OOK TX app, it does not use predefined encoder chip protocols — instead you define the payload bit-by-bit, either by typing it directly, using the Bug Key composer, or loading a .OOK file from the SD card.

This app is a lightly enhanced version of the ROOK application by @sasaga.

Controls

• Frequency / Gain / AMP: Standard TX controls. Default frequency: 433.920 MHz.

• SampleRate: The baseband sample rate used for transmission. Options: 250k, 1M, 2M, 5M, 10M, 20M Hz.

• Step: Increment used when adjusting SymbolRate and PauseSymbol fields with the encoder. Options: 1, 10, 100.

• SymbolRate (0–9999): Number of symbols per second.

• Repeat (1–999): Number of times the payload is repeated per transmission.

• PauseSymbol (0–9999 µs): Pause duration between repetitions.

• Payload: Displays the current bit string to be transmitted (0 = carrier off, 1 = carrier on).

• Set: Opens the text keyboard to type a payload manually.

• Open File: Opens a file browser in OOKFILES/ to load a .OOK configuration file.

• Save File: Saves the current settings to a .OOK file in OOKFILES/.

• Bug Key: Opens the Bug Key composer view (see below).

• Waveform: Live preview of the current payload's OOK waveform.

• Send / Stop: Starts or stops transmission.

Bug Key

The Bug Key is a quick pattern composer. It appends repeated 0 or 1 bits to the payload using configurable step sizes.

• Primary Step (0–550): Number of bits appended by the short buttons (0 and 1).
• Secondary Step (0–550): Number of bits appended by the long buttons (00 and 11).

Button	Action
0	Appends Primary Step × 0 bits (carrier off)
00	Appends Secondary Step × 0 bits (carrier off)
1	Appends Primary Step × 1 bits (carrier on)
11	Appends Secondary Step × 1 bits (carrier on)
