Starting from 1.2.1, I can update my Audiomoth 1.1.0 units up to firmware version 1.3.0. Then if I update to 1.4.0 everything seems to go on fine but at the end I get: "No AudioMoth found". Config app does not recognize the unit either. I can flash to 1.3.0 again using the paperclip and then everything works. Note that 1.3.0 supports automatic switching to flashing mode, but I have tried with a paperclip as well.
The problem happens with all versions >= 1.4.0 I have to work with 1.3.0
ok, directions for Windows 7 users (please note I have my OS in Spanish and I translate, so some technical terms might actually be different):
Update to 1.4.4 following standard directions
Everything goes smoothly, but in the end you get the message "No Audiomoth found". If you try the Config app, it will not recognize the unit. This is not a problem of Audiomoth, it is a Windows 7 problem.
Go to Device Manager and find there a USB with a sign of alert (unfortunately did not get a screenshot of it and it's not there anymore..., I think it was under the section HID devices, then an USB device there), right-click and select Properties, then Driver and Update driver. Select and wait for the system to look over the internet for an updated version of the driver that will be automatically installed. Be patient (it's windows...)
The config app should now recognize your Audiomoth unit.
Great! Can you add some screenshots and instructions on this thread for the next person who encounters this issue.
Solved by just updating the driver from the Device Manager itself.
Hi Agustin, Yes, I remembered that thread and we never really got to the bottom of it. It worked okay for me with a Windows 7 virtual machine but that may not be a reliable test. It shouldn't affect the updating so if you can update them on your machine and then try them out on another, that would be really useful. Alex
After reading
https://www.openacousticdevices.info/support/flashing-support/flashing-1-4-then-no-audiomoth-detected
I was just going to add that info: I'm using Windows 7 and the last version 1.1.0 of the Flashing application.
It certainly looks like driver problem for Windows7. Rebooting does not solve the issue and I can see in the device manager that there is a problem with one USB device as soon as I connect the Audiomoth with firmware >= 1.4.0
If there is a simple fix to this, let's try it, but please do not invest a lot of time on solving this problem: we should not be using Win7 (I apologize) and people can move to linux for free. You could just note that apps require Win>7 for firmware >= 1.4.0
Nevertheless, I will check with other machines (Win >7 and linux) soon and will report back.
Thanks a lot for your work.
Hi Agustin, Can you confirm what operating you are using. Does this occur with one AudioMoth or multiple AudioMoth? Can you check that you have the most up to date version of the Flash App. Version 1.4.0 onwards support WebUSB as well as USB HID protocols. Check if restarting your computer sorts out the USB drivers. Alex
