I have 2 AudioMoths an AudioMoth Dev and a µMoth both of which I bought recently. Whilst attempting to commission both devices I have successfully configured and updated the AudioMoth Dev to 1.7.0 having been prompted to do so by the AM_config app.
The same process did not work for the µMoth, the AM-Flash app started the update but stopped half way through at the bootloader(?) stage (light blue bar part way across)? I have not been able to get any of the AM software to recognise the µMoth since. The USB cables are the same in each instance; the AM Dev appears in the Mac hardware report under the USB 3.0 hub but the µMoth does not. Rebooting the Mac has no effect.
I have looked through many posts here old and more recent but nothing I try connects the µMoth to the Mac. There is 3.0V available from the µMoth auxiliary connections and the switch on µMoth has continuity when operated in all three settings. No LEDs light up now at any time. The AM software does not become enabled (because the MAC is not showing the µMoth as being connected?) Attempting the 'Manual Instructions to Switch to Flash mode' in the Flash app using the paper clip has no effect, the Current Status says 'No Audio Moth found'. Any advice on how to recover an otherwise brand new µMoth would be much appreciated.
(The Mac is an Intel model - not a new M1. The µSD card is formatted Ex-FAT but I don't think that's relevant as it is not populated to update the firmware. I have tried connecting to the AM Flash app with the µMoth switch in both the Off and Config positions.) Many thanks,Steve
Hi, You will be able to recover this uMoth by selecting the 'Show Manual Switch Instructions’ menu option in the Flash App. This will guide you to apply USB power whilst holding a paper clip on the two programming port pins marked with a curved line. The images show a regular AudioMoth but the sequence is the same for AudioMoth. The Flash App will then recognise the device. The key step is to ensure that the AudioMoth is powered down, and then to hold the paperclip on the contacts so that when power is applied via USB, the AudioMoth immediately sees that is should start the bootloader (flash mode) rather than the regular firmware. It's a bit fiddly but will definitely recover any AudioMoth that has suffered a stoppage during firmware update. Let us know if you have any problems. Alex
Thanks for the post Alex but the process you describe has not connected the µMoth to the AM Flash app, the app show 'No AudioMoth found'. I am powering the µMoth with a single LiPo. I have tried this before several times taking care to change the switch from 'off' to 'custom' for the 'Manual switch' procedure.
I downloaded the Flash app to a new M1 MacBook pro but got the same result. The M1 recognises the AM Dev and it appears in the hardware config as you'd expect but the µMoth does not. Is there an alternative to the Manual Switch procedure that I can try please? Many thanks.Steve.
You need to disconnect the battery whilst following the manual switch instructions. The aim is to make the uMoth power up via the USB cable and immediately find that the bootloader pins are shorted together. It is a bit fiddly but will definitely work in the end.
