Micro. Try it first though šŸ‘ Ideal for a tracker build for those crazy 500m 120m high flights ---

Hmmm. Back on topic. I canā€™t for the life of me get this buzzer to stop buzzing constantlyā€¦ The resource for the buzzer is E03 (which I have checked and double checked the defaults). I have checked for any shorts and itā€™s all good. The BZ+ on the FC seems to be connected to the rest of the 5V out (which is normal and fine), the GND is OK, and the BZ- seems isolated from any other pad Iā€™ve put the multimeter too. Hereā€™s What I gotā€¦ (marked the pins Iā€™m using with a red dot) ![image](https://d1q8cepst0v8xp.cloudfront.net/original/3X/9/9/9959b4595e765a45c3ab265e8b8e9cd81d0bf956.jpeg) ```auto FC BUZZER BUZ+ ------------------- 5V BUZ- ------------------- B- GND --------------------- GND ``` Have checked and switched all the beeper\_\* options in CLI to check ```auto # get beeper beeper_inversion = ON Allowed values: OFF, ON beeper_od = OFF Allowed values: OFF, ON beeper_frequency = 0 Allowed range: 0 - 16000 ``` It did work pre 4.4 update which is interestingā€¦ Iā€™m pretty damned sure it did. Also it does ā€œseemā€ to work briefly (reflashedthe FC this morning and it kind of started OK, then went to just a constant buzz). Have also tested a known working buzzer from my other quad and shows same issue. ---

Actually might downgrade to BF4.3 and see if that helpsā€¦ ---

Is there a way in betaflight to show that the beeper is ā€œactiveā€ or any error messages (there are none appearing in the OSD error messages that is). The RF mode is definitely not active, i.e. buzzer signal ON from the RX ---

Thereā€™s a visual beeper in the OSDā€¦ 4 starsā€¦ Also you can switch on motor beepingā€¦ Hmmmā€¦ could it be the frequency? ![image](https://d1q8cepst0v8xp.cloudfront.net/original/3X/0/5/05868232c64d4a8c8a86d254bbbaa94da3385cb4.png) ---

> [@Yith](#): > > Thereā€™s a visual beeper in the OSDā€¦ 4 starsā€¦ Yeah, non of that, and itā€™s the INSTANT you connect the Lipo. Constant and LOUD! > [@Yith](#): > > Hmmmā€¦ could it be the frequency? Not tried that. you using 3800 on yours? Same kind of buzzer with Lipo? I always thought these were set to 0ā€¦ Will give it a go. tried 4.3 and no difference so going back to my 4.4.1 build ---

Beeper inversion did what you describeā€¦ try switching it. You need to save for it to take effect ---

Iā€™ve switched it loads mate šŸ˜‰ It was what sorted the original problem back when I first reported itā€¦ Wonder if need to turn it off and leave off and back onā€¦ Itā€™s so loud to test and annoying to the neighbours, lol ---
