No serial ports found


Hi, I'm trying to update the firmware and have downloaded the relevant flash app and firmware file. When I run the flash command, however, no serial ports are found. I can't work out what the problem is, could anyone help? I'm using a Linux machine (Ubuntu 18.10)


$ chmod a+x flash

$ ./flash

No serial ports found

Hi Ella,

Have you put the device into programming mode Correctly? To confirm this, switch the switch to CUSTOM, after the prog pins have been shorted using the paper clip routine, the LEDs should stop flashing. This indicates programming mode.


Hi Andy,

Thanks for getting back to me so quickly.

I was actually only on Step 3 when I was getting that message as I was expecting the ports to be displayed then. Once the AudioMoth is plugged in and in programming mode I get this error:


$ ./flash -u /dev/ttyACM0 AudioMoth1.2.1.bin

ERROR: Could not open port

What do you get if you just type


And press enter?

  • Hi there, could someone please point out where I’m going wrong? I’m trying to edit the default settings of the firmware but I’m rather new to all of this stuff. I have tried editing the variables in the main.c file from AudioMoth-Firmware-Basic, then replacing the main.c file of AudioMoth-Project with it, and then building this entire project using the Simplicity IDE. Then I use the .bin file located within the ‘GNU ARM v4.9.3 Release’ directory to flash the firmware of the device. This however results in the device being bricked and requires me to reinstall the regular firmware. What am I doing wrong? Thanks in advance!
  • Have downloaded apps, the greyed-out areas remain the same, ie. unable to change. When connected to PC solid green light appears.
  • Hi there, can anyone please help me out? I would like to schedule audiomoth to make 5 minutes records every hour during the whole day (thus 24 files per day). However, after twelve hours, only one 5 min file was recorded. I used exactly the same configuration in a second audiomoth device and three five minutes files were recorded. Find in attachments the image of my configuration app. Thanks a lot in advance!
