EaKiu can record and playback Wi-Fi data. Files are recorded by EaKiu in the CSV (Comma Separated Value) format. Each device in the system can record a separate CSV file simultaneously if desired. RECORDING WIFI DATA Normally EaKiu is not in record mode and the OUTPUT and Recording Information show no light and read "Not Recording". To start EaKiu recording data for the currently viewed device click the RECORD button in the OUTPUT area of the window. Use can also start recording by typing the r key. To stop a recording make sure the same device is displayed and simply click the RECORD button again, or type the r key again. If this is the very first time you have started a recording (and you have not snapped an Image yet) you will immediately get a Folder Dialog to allow you to select the desired Folder to store the recording. Select the desired folder from the Folder Dialog and then the Choose button to being recording to that folder. If you have already selected a Folder in a previous session, the last folder you selected will be automatically used to store the recording and you will not see the Folder Dialog. To change the Folder to another Folder, click the small File Icon in the upper center of the window. Once you are recording the RECORD button light will be green and the name of the file you are recording will be in green in the Recording Status area. file names are organized as follows:
Where 'YYYY' is the year, 'MM' is the month, 'DD' is the day and 'HH' is the hour, 'mm' is the minute and 'SS' is the second. 'n' is an incrementing number to avoid duplicate file names. The files are in CSV (Comma Separated Value) format. The first four records contain identification information that is required for EaKiu to be able to play back the files. The actual data starts with the fifth line in the file. NOTE that if you have old EaKiu CSV files (from before version 4.0) you can make them play under the current EaKiu by adding one line to the top of the file:
# dBm Range: -61.000000/-1.000000 khz Range: 2400000/2484000 Samples: 85 PLAYING BACK A WIFI RECORDING Any CSV file recorded either in EaKiu or the MetaGeek software can be played back in EaKiu. To play back an existing recording, simply click the CSV button in the SOURCE area. As soon as you click the CSV button you will immediately get a File Dialog asking you to choose the desired file to play back:
 Click on the desired file and then the Open button and the file will be loaded and will begin playing back. While the file is playing back the CSV button will be lit green and the name of the file being played back will appear in the Status text area. CSV files play back at the same speed that they recorded at. The file will continue to play to the end. Once it reaches the end it will automatically Pause. To play the file again simply click the Pause button. To stop playing the CSV file click the CSV button again. HOW PAUSE AFFECTS RECORDING AND PLAYBACK The PAUSE button in the CONTROL AREA will pause both Recording as well as Playback for the current device, when used. While the system is in Pause mode, no data for the current device will be recorded and no data for the current device will be played back (playback is actually paused). Recording and/or playback for the current device will resume once you take the system out of Pause.
