AMs not recognising chime

Hi there, I used many Audiomoths last summer and all went well. However, this year they are not receiving the chime from the app. Both the firmware and app are up to date so I'm not sure what the issue is.

Can anyone provide any advice?

The devices record in default fine and can be set with a time from the laptop. I am using a custom schedule (same as last year).

Hi Sophie, Are you on Android or iOS? Do you know what firmware the AudioMoth are using? If they are earlier than 1.10.0 they will not recognise the chime when the location is used. In that case you can just switch off location on the app and this will then set the time correctly. Alex

Hi Alex - great to see you in Madrid. What's the difference between 1.8 and 1.8.1 in terms of Chime. We are just starting to use the chime and already have 40 moths deployed in the field. They are running 1.8 ATM. We can reflash them in the field, but do we need to?

Hi Simon, If the chime is working fine for you there is no need to update. Version 1.8.1 improves the reliability of the chime on some phones. Other people didn't have any problems, or just needed to press the 'Play Chime' button a couple of times before the chime was recognised. Updating in the field is easy - you just use the Flash App to replace the firmware. You can run the Flash App somewhere with an internet connection first and download the necessary firmware. You will lose the installed configuration when you update the firmware, so the configuration will need to be set again with the Config App. Alex

Thanks Alex - yes, it seems to work for me with just 1.8. Medium/low volume seems the key. Yes, we were planning to just flash it in the field, but then there's always the config as a second source of error, so I think our plan of attack is to see whether the chime worked (thanks for the LED signals!) and if yes, let sleeping moths lie.
