Great new features, thanks to the whole team! Would it be possible to have custom 'maxim file length' in the Expan AudioMoth Recordings? We normally split files into 5 seconds, and sometimes into 2 seconds, depending on the survey. Besides, 5 seconds files is quite common among bat surveyors and researchers. Many thanks!

It worked beautifully! Many thanks Alex!

Hi all the team, first of all congratulations for the great new developments, they are very welcome and your time and dedication much appreciated. They will certainly make a difference in bat research. We've been customising the firmware in the previous versions and Simplicity Studio has been working smoothly so far. I've just imported the latest project version with the main.c & digitalFilter files but I cannot build the binaries (unmodified version, just for setting up and testing so far) because there are some seemingly undefined references in the 'digitalFilter.c', which actually seem to be functions from the math.h library, which is invoked at the beginning of the code. I list them hereafter: • tanf() • hypotf() • sqrtf() • csqrt() • cosf() / sinf() Any idea of what can be happening? Is there any extra driver/library that needs to be installed to work on this versions? main.c also makes use of 'math.h' without issues. Many thanks in advance! Best, Xavier

Hi Alex, Thanks for the quick answer! We solder the batteries onto the terminals. After following your instructions I've noticed that the only devices that don't work fine are those we welded power cables to yesterday. Please apologize for rushing the question, I should have double checked that before. Thanks,

Hi again, would it be possible to know the expected date of arrival of the devices? Invoice number is bdc5cc9e73df8cbaf1b2837260dff4ba . We are to conduct some field work by the end of the month for which the AudioMoths are an essential part. We didn't expect such delay when planning it a few months ago. Please, provide some feedback. Many thanks,

Thanks Alex! I'll try it again following your explanation. The green LED issue might be misleading in this case because I also made other changes in the firmware that may be responsible of its flashing. I'll try on a 'clean' version with no further changes. Best, Xavi

Hi Alasdair, We look forward to start working with the devices. Many thanks, and congratulations for the great work you are doing. Best,

Hi, I see there have been deliveries since late April and we haven't received any units yet. Should we expect to receive them or there's been some problem with our delivery. Many thanks,

@David Brown Thanks! We'll keep an eye on it...

Hi David, That's very good news, since the vents are difficult to get, but I cannot find the campaign... Is it still on? Thanks!

Thanks for the quick replies, and sorry for the silly question. David Lee's answer point to I was doing wrong: instead of getting the recording time from the filename or the metadata (we normally run a script to do so) I was quick reading the dates from the folder explorer in my computer, which shows GMT dates and applies the time shift accordingly. Thanks!

Thanks Alex! That's great news. Best,

Thanks Alex, sorry for the late feedback. We've tried with three different machines runnig Windows 7 an the problem seems to persist. The workaround we've found is to install the Simplicity Studio and from there install the drivers for the board. Best regards,
