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,20MHz. -
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.OOKconfiguration file. -
Save File: Saves the current settings to a
.OOKfile inOOKFILES/. -
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 (
0and1). - Secondary Step (0–550): Number of bits appended by the long buttons (
00and11).
| 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) |
