I have the same problem, import charges of €44 as the enclosures "are from outside EU" (Fedex). I'd never experienced this before.

Hi @Andy, you mentioned in your post above that you hardcoded recording schedules into the firmware. Could you please explain the procedure to hardcode recording times for every selected days in the firmware (ie which files to modify https://github.com/OpenAcousticDevices)? I believe that the Audiomoth does not memorise the actual recording times but merely keeps track of the time to the next recording period (https://github.com/OpenAcousticDevices/AudioMoth-Firmware-Basic/blob/master/main.c). If that's right, I can't see how to hardcode times for every single days. I'd like to hardcode sunrise/sunset times. I believe this option will be available in the next Audiomoth version (the one with the external mic option)? Many thanks EDIT: although not about hardcoding different recording times for every single days, this post deals with hardcoding a specific starting date for recording.

@Mike Hi Mike, how did the double battery pack work? Is it reliable and works as planned (ie. putting 3 new batteries before removing the 3 old ones so that it never loses power and configuration parameters)?

Hi Alex, your post on twitter was really eye-catching. Do you have any news about the next Audiomoth with external microphone ? https://twitter.com/OpenAcoustics/status/1185968565960220673

Hi Alex, We're looking forward to trying the new WAV file approach in the field when the firmware is released. It's good to know that the SD card can be pulled out without resetting the recorder configuration. Many thanks to the team for improving the firmware, adding new functions and keeping us updated, and good luck to Peter with the Ph.D.

Hi Alex, Thanks for the update, that is great news. If I understand well, the user will have the choice between the three options. For our project option 2) would fit our needs, although best if we can record from some specified time after sunset to some specified time before sunrise. This would permit recording periods within the night. Unless the specified time can be negative and interpreted as after sunset or before sunrise (-20 minutes before sunset being 20 minutes after sunset)? Precision wise, sunrise/sunset times rounded to the nearest minute would be best and would optimise battery life and SD card capacity. However I guess this is project and goals dependent. I reckon you are making substantial changes to the firmware : - would you have a broad timeline for the release of this firmware? - you mentioned the possibility of pulling the SD card and putting it back in with the recording continuing as planned at the next scheduled recording (https://www.openacousticdevices.info/support/sd-card-support/large-cards), will that be included in that firmware? - the limiting factor is currently the SD card capacity as we can use higher capacity external powerbanks (https://www.openacousticdevices.info/support/device-support/powering-using-external-usb-powerbank), will there be an MP3 encoding option in this firmware? Also you mentioned the 'AudioMoth Labs' on another post (https://www.openacousticdevices.info/support/configuration-support/programming-to-adjust-for-sset-and-sris-change-each-day), is it still being considered?

Hi Peter, Thanks a lot for the help, I managed to rewrite a routine (from your C code to an R script) forecasting consumptions and file sizes for a given period, sample rate, sleep duration and recording duration. Your documentation on the microphone settings and how they define the configuration bit also helped : https://github.com/OpenAcousticDevices/AudioMoth-Project/wiki/Microphone-Settings
