This enables the replay of a previouly recorded files that has been recorded from a capture or generated to simulate the transmission. This app allows users to replay single play C16 file, or create playlists of previously captured signals and replay them in a specific order.

For OOK Transmissions, a [DeBruijn](https://en.wikipedia.org/wiki/De_Bruijn_sequence) attack can be used. This can be used on non-Cyclic code key system such as garage doors, gates and some old cars. # Replay Single File
Two set of files have been prepared for the portapack in the link below. One is for binary and other for trinary for different key code lengths. Information can be found in the link. The files need to be place in a folder on the SD card but note the trinary ones are very large. Select a C16 file, it will replay your C16 file referring the freq and rate config of it's partner file.

# Playlist
A video tutorial on the general use of the App is shown here: https://www.youtube.com/watch?v=Pe30Jvyhmzk A sample PLAYLIST.PPL file is included in the SD card.
The file with PPL extension is just text file, you could edit it with any of the text editor.
Playlist files are comma delimited and have the following structure:
ABSOLUTE_PATH_TO_C16_FILE,DELAY
#COMMENTS
For example, a valid playlist file could contain:
```
# Playlist file example
# capture path, pre-delay milliseconds (optional)
/SAMPLES/TeslaChargePort_US.C16
/SAMPLES/TeslaChargePort_EU_AU.C16,100
```
It will do:
1. Play SAMPLES/TeslaChargePort_US.C16 referring the freq and rate config of it's partner file
2. pause 100 ms
3. Play SAMPLES/TeslaChargePort_EU_AU.C16 referring the freq and rate config of it's partner file
4. over.
The LOOP check box is for the entire PPL file.
Once you interrupted the replay, it would start over since the beginning of the list.
