I've just gone to https://www.openacousticdevices.info/getting-started and clicked on the link for the configuration PDF, and it's for the old version of the Config app. Is there a new PDF available for version 1.3.1 ? TIA :)

I'm using the latest version or Windows 10 64bit, just updated the laptop with it and rebooted a couple of times to ensure all is running OK... which it seems to be... I've downloaded the latest version of the Flash app and am trying to update the device by clicking the Download button, then the Flash button. Whereupon the app tells me it's applying the firmware to the attached device for about 5 of minutes, before then telling me in ever recurring countless popup dialogues "Ready signal was not received from AudioMoth. Switch to USB/OFF, detach, reattach your device, and try again." until I close the Flash App. (I went and got some new batteries without closing the app, got back about 10 minutes later, and the app was still producing popups.) I have done the above a couple of times, and put a new set of batteries in too... still no luck :( Any pointers gratefully received :)
