Hi All - Hoping someone may be able to assist? I'm fairly green when it comes to drones so excuse the terminology So I've recently installed a 5v Matek Lost model beeper to my x220, and followed a pretty straight forward guide - connecting power source to VBAT and then connecting buzzer to the points marked on the board as per below images All seemed pretty straight forward and to some extent works fine... Now my problem. When i fire up my drone i hear the power on beeps (from the new buzzer), arming beeps, failsafe beeps and probably more but for some reason when i flick my lost drone switch on AUX3 i can see that LED blinking faster but no beeps, i also don't hear any beeps for lost connection when i turn off my controller. I've turned betaflight upside down trying to find something that looked odd, but have exhausted everything i know and everything i have read to no avail. My switches are setup correctly and work fine, Ive disabled and re-enabled all beeper settings through CLI commands and the config, and also restored all settings to default with no resolve.. Its driving me nuts and i'm sure its something i'm overlooking - but now i'm lost. Any help would be much appreciated!
