AudioMoth Flash App Now Available

Applying new firmware to your AudioMoth just became much easier with the release of the AudioMoth Flash App. With this application you can easily download and apply updates to the default AudioMoth firmware as we release them. If you've written your own firmware variant then you can apply it using this application too.

Download app here

If you're applying new firmware to a device currently on 1.2.2 or older, then a paperclip will be required to manually put the device into flash mode (instructions for doing so are found in the app).

Post any support queries in the new forum section here.

Peter - an info report - On Windows 10 Home 1909 - the flashapp bricked both my AudioMoths. Then I couldn't get flash to load the firmware either, after much pluggin unpluging and rebooting - Windows decided to reinstall the USB/COM driver as COM4 whereas flash had been reporting the AudioMoth as COM3. Using COM4 - flash did it's thing and now I have both AudioMoths back reporting the correct firmware.

The Flash app doesn't work!

The app will find an AudioMoth in flash mode - either automatically if v1.3.0 is installed or following manual set up of flash mode with earlier firmware - and when a downloaded firmware is selected the "Flash AudioMoth" button is enabled.

Iniitially the "Flashing AudioMoth" pop-up is displayed and (if flashing from v1.3.0) the correct COM port opens. However this is followed by an error dialogue: "Failed to open port" and the AudioMoth is left in an unresponsive state. A firmware must then be installed manually, using the original Flash utility.

This version installs the firmware but then throws the same error dialogue, ie "Failed to open port ..." etc

The program is failing to close the flash COM port after the firmware update, which then remains locked open until power is removed from the device. The firmware has been installed successfully but the batteries must be removed and the AudioMoth disconnected from USB power in order to close the port before the device can be configured and/or operated.

However the app is seriously unimpressive! The command line utility is only 121Kb and flashes v1.3.0 firmware in only 10 seconds whereas the new app is 84MB and takes around a minute and a half - that's quite a penalty to pay for the benefit of avoiding having to short two PCB terminals! If it is the best that can be done with Node.js then I suggest it would be preferable to fix the timing issue in the original command line program that causes it to crash on first run when updating from an existing firmware at v1.2.2 or later.

I'm continuing to look into the port problem, could you share the log file so I can pinpoint where your app is having issues?

Could I also have a bit more information on the machine you're using to run the application? We've been testing on multiple Windows 10 machines and have been unable to replicate this bug.

I've just attempted to flash v1.3.0 again. This time the app failed immediately first time and I had to put the AudioMoth into Flash Mode manually. After doing this the app re-loaded the firmware but failed to close the COM port as usual.

I've attached the log file here.

If you've never updated the firmware on your AudioMoth, now's the best time for it! To get all the improvements and bug fixes implemented so far just download the app and download firmware version 1.3.0.
