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!
The manual has now been updated to be clearer. Thanks for the feedback!
Hi Edder, Thanks for highlighting this confusion in the manual. The batteries are not needed during the flash process. To be safe, we recommend inserting and removing the batteries before the first configuration to make sure any previous firmware settings are fully reset. Thanks, Andy
