    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!

    I was the same with the same boards.
    & could never get it going & gave up.
    I had the esc's but it just gave me more of an incentive not to lose it.
    I know it's the ground wire that actually triggers it & not the 5v.o_O

    Still waiting for a vendor in UK to stock the drone keeper mini. The shipping tax from abroad is more than it costs.
    I voted brexit but its getting out of hand now. Prices are nuts.

    So the problem has been solved!....

    Credit to Voodoo614 on RC Groups - The Matek buzzer has to be wired differently to others as it is an active buzzer, not passive.

    Before rewiring the buzzer i did manage to get the lost signal beep working by switching to ibus over ppm, but this still didn't give me the lost drone beep

    Everything now beeps as it should - Happy Days!!! :)

    Thanks for sharing the solution. I have a Matek buzzer with LEDs I still need to hook up to one of my quads.
