pippyg2.1 - App Store

This tool gives you a convenient and reliable method to set the real-time clock, device ID, deployment latitude and longitude, and wake and sleep times for the PIPPYG bat recorder bat detector, in the field, using just your phone and the PIPPYG's onboard microphone.

To use the app, set up the configuration you want in terms of Device ID and sleep/wake times, turn your phone volume up to between 1/4 and 1/3 full volume and place your phone's speaker about 4 - 6 inches your PIPPYG's microphone. Now press the Configure / Deploy. SInce the PIPPYG red LED responds to sound after power-up, it flash when your phone makes the "triple chirp" sound. If the LED flashes just when it is responding to the sound, the PIPPYG did not successfully decode the data packete encoded into the chirp, so you need to try again - try changing the phone volume (typically quieter is better), adjust and the distance from the microphone, or positioning the phone more carefully relaive to the PIPPYG - it helps if you point the phone's bottom speakers right at the microphone hole, from a few inches away. If the PIPPYG's red LED flashes 8 times in rapid succession, you have successfully programmed your device, and it will enter a wake/sleep cycle, recording bats (or birds) when it is awake.

Note that this app works with both self-build PIPPYG units and with commercially-produced Apodemus PIPPYG and PIPPYG2 devices.

Version History Tripled-up chirp to improve reliability when used with new firmware pippyg_v10-27-08-26.uf2.
Internally corrected "NUMSTARTBYTES" in the "payload.h" header to work with old and new firmware. 2.1 Aug 27 Bugfixes 2.0 04/22/2025 Slight modifications to support older iPhones / iPhone 6 / iOS 12.2 1.9 04/06/2025 In the Settings app you can now control recording trigger sensitivity, and select Bird Mode to record at 48kHz rather than 384kHz. 1.7 03/18/2025 Version 1.6 introduces a new control for "Interference Suppression" which requires version 1.6 device firmware. 

When turned on the device accumulates any signal, no matter how strong, into its running noise fingerprint, which allows it to ignore and hence not continuously trigger in the presence of for example a rodent deterrent, a fluorescent lamp or other strong, steady ultrasound source. When turned off, only weak signals are allowed into the noise fingerprint, so in that case the noise fingerprint will tend to be a measue of the ambient environmental noise, with powerful environmental signals not taken into account. 1.6 05/19/2024 It is strongly recommended to update your app to this version. A bug in timezone processing was fixed in the previous version 1.4.

In this version the smallest recording size has been changed from 4MB to 3.8MB, which makes the recordings exactly 5 seconds long. This optimises them for processing by the BTO Acoustic Pipeline, potentially saving you a large number of upload credits over a season. 1.5 05/06/2024 A fix to make the date and time passed to the detector match that of your phone 1.4 03/14/2024 Daylight Savings Time is now honoured, so the recordings on your devices matches the time on your phone. 1.3 05/09/2023 Bugfixes, specifically an increase in the number of start bits of the modulated message to place less pressure on the CPU of the receiving device. 1.2 03/09/2023 Better UI layout for iPad.
Bug fixes.
Removed timezone as it was not necessary. 1.1 03/06/2023 1.0 01/10/2023
