Unsuccessfull Flash Process (1.2.1) (mac/osx)

Hi All, I tried to flash my AudioMoth from 1.2.0 to 1.2.1 and lamentably I didn't finish successfully. I appreciate in advance the solidarity of the Audiomoth's Community. To summarize: 1) I downloaded the last firmware to flash from: https://github.com/OpenAcousticDevices/AudioMoth-Configuration-App/releases

2) I downloaded the flash tool for Mac Users from:

https://www.openacousticdevices.info/flashing

3) I executed the step by step from: https://www.openacousticdevices.info/flashing


4) During the step 7). Step 7: Flash AudioMoth device, the bash print the error "ERROR: Timed out waiting for send confirmation from AudioMoth", that seems that the Audiomoth is not reachable: I reviewed that the AudioMoth is in "custom" switch on, without batteries and without micro SD Card, so the pre-requirements are ok.


The troubleshooting process that I executed was:

1. Repeat the process . The results was the same error.

2. Execute the process as a root. The results was the same error.

3. Change the privilegies in flash executable and also in the device: chmod 777 dev/tty.usbmodem14201 chmod 777 flash A new error appeared ERROR: Did not receive response from AudioMoth after sending chunk Below is the terminal print screen: sh-3.2# cd Desktop/flash/

sh-3.2# ls

AudioMoth1.2.1.bin flash

sh-3.2# ./flash

/dev/tty.usbmodem14201

sh-3.2# ./flash -i /dev/tty.usbmodem14201

Serial Number: 248C7D075B2BEB30

sh-3.2# ./flash -u /dev/tty.usbmodem14201 AudioMoth1.2.1.bin

ERROR: Timed out waiting for send confirmation from AudioMoth

sh-3.2# ./flash -u /dev/tty.usbmodem14201 ./AudioMoth1.2.1.bin

ERROR: Timed out waiting for send confirmation from AudioMoth Best regards from Chile, Neotropic. Cristián Pinto // cristian.pinto@ymail.com

Appears that your flash command is not being executed inside the specified directory. (I’m ignoring the minor typo in Audio)

open terminal app


cd ~/Desktop/AuidoMoth


make sure that the command working directory is changed to the directory supplied.


chmod a+x flash

./flash -i /dev/ttyACM0



substitute ACM0 for the device path as found when connected to the USB port, the paper clip is connected, and the switch moved to the custom position. Find the device by running


ls -l /dev/tty*


before and after connecting the device. the new device will be appear is the list after the device is connected.
