AudiMoth Dev not recording

in Device Support

Hello Alex, I got my AudioMoth Dev today, and I gave a first try.

When connected with the USB cable, it looks to be OK.

I connected a LiPo battery 3.7 V the rigth way. The green LED is fixed.

I am using a µSD 32 Gb freshly formated Fat32

When I put the swicth to DEFAULT or CUSTOM, nothing is recorded. The two LED are falsing together slowly then rapidly.

I noticed that the first time the µSD was a bit difficult to be inserted.

I flashed the "External-SRAM-Check-1.0.0.bin" => the green LED is flashing...

Do I miss something ? Best regards

Pierre

Just to confirm. Does it record okay when powered by USB without the battery connected but with the SD card plugged in? Switch to DEFAULT and it should start making a recording immediately, flashing the red LED.

AudioMoth USB Microphone firmware, Default switch, USB connection, No SD : the Capture option is OK. A WAV file is saved
AudioMoth USB Microphone firmware, Default switch, USB connection, With SD : green LED flashing fast, nothing recorded, no CONFIG.TXT available
Test with Firmware 190, battery, SanDisk Extreme 64Gb/exFAT, Default swicth => same result (2 LEDs flashing 5x, no CONFIG.TXT

I think there is something wrong with the SD card connector. Contact andy@openacousticdevices.info and he'll be able to arrange a replacement. Let him know that it has just arrived and where it was sourced from.

When I am using the AudioMoth Live App, nothing is visible into the blue window, as it was when I was trying the HydroMoth, neither with the built-in micro neither with an external micro.
