Hello
I would like to record birds and bats with different settings: for birds: 7:30 am to 6:00 pm, Sample rate = 48 kHz, Gain = Med, Sleep Duration (s) = 1500 and Recording Duration (s) = 300. For bats: 6:15 pm to 7:15 am, Sample Rate = 256 kHz, Gain = Med, Sleep Duration (s) = 45 and Recording Duration (s) = 15; UTC +3. It would be possible?
I can't make it.
Hi Cintia, We have a custom version of firmware that will supports this configuration. We'll eventually be posting this on AudioMoth Labs but if you email me directly (alex.rogers@cs.ox.ac.uk) I can send you a link. Alex
Hi Cintia, The firmware for this can be downloaded from:
https://www.dropbox.com/s/ku8gjdrw0ecwdjr/AudiomothBirdsAndBats.1.0.1.bin?dl=0
You use the Time App to set the time. Switch to CUSTOM to start the program running. Switching to DEFAULT will make instantaneous recordings using the settings of the first recording period (which in this case are the 256KHz sample rate settings).
It's very quick to make a new version if you need to change the configuration settings. We're working on an easy way to do this from a website - AudioMoth Labs - but it's a manual process of editing the source code and recompiling at the moment. That said, this only takes about 60 seconds.

If anyone else wants a version with different settings, let us know here.
Hi Alex! We would like to record only bats, but with different settings depending on the moment (lower sleep duration at dawn and dusk, in order to have more frequent recordings in both moments, and less during the time between them). Would it be possible? Thank you very much
Hi Alex, Could you provide a custom firmware that will perform the recording schedule as mentioned below:
6am to 6pm; Recording: 5 min; Sleep: 0 min; 48kHz - sampling rate, Med Gain
6pm to 6am: Recording: 5 min; Sleep: 0 min; 256kHz - sampling rate, Med Gain.
Hi Alex, I have downloaded the firmware above, however, when trying to flash it, I get an Error: Could not open file. I don't have a problem installing any other firmware versions. I would also like to record bats and birds in different sessions with one device. The trigger option for bat surveys is not available yet?
Hi, Make sure that the firmware .bin file and the flash application are in the same folder and that the name of the file that you enter in the terminal matches that of the actual file. Can you send a screenshot? Alex
Hi Alex, thanks for your quick response. Yes, as far as I can see it's all correct?
Strange. That should work fine. Does it work for the AudioMoth1.2.1.bin file?
Yes it works fine for that one. I've tried different devices to check if that was the problem, but same thing. Can install the 1.2.1 version but not the Birds and Bats one.
I think there must be something wrong with the file. Can you open it with a normal file viewer? Try downloading again from here - https://www.dropbox.com/s/ku8gjdrw0ecwdjr/AudiomothBirdsAndBats.1.0.1.bin?dl=0
Hi, yes it seems to open fine with a file viewer. I downloaded again, but same error message.
Are you sure the filename that you are entering matches exactly? I can't think of any other reason why it can't read it.
Are you sure the file is in the correct location? The screen shot of the file system doesn't seem to match the directory of the file where you are running flash from. If you type >DIR in the terminal window, can you see both the flash application and the binary file?
Oh dear, I honestly don't know how that happened. I had problems before because something didn't run on this user account so some was saved in the same folder but under the admin account. So sorry about that. BUT unfortunately I still get an error message, only now it is saying "Error: the file is too big"
Can you show a screenshot? How big is the binary file? It should be 45KB which should work fine.
Ah, you don't have the binary file saved, you have the webpage from DropBox saved. There should be an option i the top right of the file to download the file. Or use the original file that you had.
Hey I got it. I downloaded the file again, correct size and it worked fine. Sorry for all the trouble and thanks for your help. Do I just set it on default now? Is it possible to change the settings for the two different recording periods?
No problem. Glad it worked.
