I am about to update the firmware on a couple hundred AudioMoths (firmware version 1.2.0) and would appreciate some clarification on the updating process. I am aware that firmware versions older than 1.3.0 will require a paper clip to conduct the "manual switch instructions". From my understanding, the process is the following -Open flash app -Take an AudioMoth (WITHOUT batteries) -Move switch to CUSTOM -Connect AudioMoth to device vis USB (LEDs should start flash) -Use a metal paperclip to connect the two contacts marked "PROG" and hold firmly until a tune is played and LEDS stop flashing (Flash app should say "Found AudioMoth in flash mode with a serial bootloader") -Move switch to USB/OFF -Press Flash AudioMoth and wait for the update to finish -Unplug AudioMoth and store until deployment I get that portion. However, my confusion is moving forward with newer updates (or updating firmware with version 1.3.0 or newer). The AudioMoth Operation Manual states that a flash update can be done by plugging in your device, flashing, unplugging the device, and removing and reinserting batteries before use to cycle the power of a newly flashed AudioMoth. However, I have read on the support forum that batteries are not needed here as well. Which is correct? Do I need to insert batteries to flash my Audimoth, or are they not needed? Some clarification would be appreciation. Thanks in advance!

This might seem like a silly question, but I would appreciate help. If the program is the same (SR, schedule, sleep/record, etc), Will a recording of a quiet morning differ in file size to morning with lots of bird activity (songs, calls, etc)? My guess is that it will not matter since all my files end up being the same size regardless of how active/loud an area is, but I would appreciate any feedback on this in case anyone has different experiences. Additionally, does this also apply to high sample rates with bats? Will a night with no bat activity vs a night with plenty of bat call result in similar file sizes? I’m guessing this will only matter if a trigger function is enabled. Thank you!

Hi Everyone! In addition to the Chime app being available for apple and android products, Is it possible to play a chime tune on a computer? If it is possible, can I also create a hyperlink on a document for others to access the tune? I saw that the British Bat Survey and Jersey Bat Survey from the bats.org.uk website had a "Play Chime" button and another project had a document with a hyperlink that takes you to a page where the chime can be played. I am currently in the process of creating a document for volunteers that will detail how to program the AudioMoth in case something happens that erases the settings, and I would like give them the option to set the time in that manner (in case they can't download the AudioMoth Time App) . Thanks! -Edder
