Hi!

I'm having trouble with my first build, which is a race quadcopter. I decided to post here as I feel this may be a newbie issue.

I have all the hardware connected and working. Configuration in Betaflight is underway and going well, all for one hiccup. 

When I try disabling horizontal mode my buzzer starts going crazy. Is there any way to diagnose this? I'm not sure what information about my setup maybe useful so I'll just try to answer best if you need more details. Although I may start with the following:

FC: Revo F405
Reciever: X4RSB 
Transmitter: Q X7

Aux1 (SD switch on Taranis) is used to switch between Armed + Armed and Air Mode
Aux2 (SA switch on Taranis) is used to switch Horizon mode on and off

I tried disabling horizon mode all together, but that only sets off the buzzer until I set horizon mode back on again. 

Cheers!

That's an odd one Frosty!

I'm scratching my head here. Can you upload a picture of how you have set things up on the modes tab?

Sure thing, here you go.

Currently the sliders cover both switch states (up/down), but if I adjust them to i.e. 1800 - 2100 and save settings, the buzzer starts going crazy. If I flip the switch into the range the buzzer goes quiet.

[edit] Also, if I remove horizon mode all together the buzzer wont stop whining whatever the switch position.

Well, I'm baffled, but I do see something that might be a clue.

At the top of the screen, it says your Revo is connected to a battery but that the battery only has 4V. Maybe the Horizon thing is just a coincidence and the beeper is warning that you have a low battery?

Here are the tone sequences to indicate the various states of the FC (These are at: https://github.com/martinbudden/betaflig.../Buzzer.md )

Quote:Tone sequences
Buzzer tone sequences (square wave generation) are made so that : 1st, 3rd, 5th, .. are the delays how long the beeper is on and 2nd, 4th, 6th, .. are the delays how long beeper is off. Delays are in milliseconds/10 (i.e., 5 => 50ms).
Sequences available in Cleanflight v1.9 and above are :

Code:

0    GYRO_CALIBRATED       20, 10, 20, 10, 20, 10    Gyro is calibrated
1    RX_LOST_LANDING       10, 10, 10, 10, 10, 40, 40, 10, 40, 10, 40, 40, 10, 10, 10, 10, 10, 70    SOS morse code
2    RX_LOST               50, 50        TX off or signal lost (repeats until TX is okay)
3    DISARMING             15, 5, 15, 5        Disarming the board
4    ARMING                30, 5, 5, 5        Arming the board
5    ARMING_GPS_FIX        5, 5, 15, 5, 5, 5, 15, 30    Arming and GPS has fix
6    BAT_CRIT_LOW          50, 2        Battery is critically low (repeats)
7    BAT_LOW               25, 50        Battery is getting low (repeats)
8    NULL                  multi beeps        GPS status (sat count)
9    RX_SET                10, 10        RX is set (when aux channel is set for beep or beep sequence how many satellites has found if GPS enabled)
10   ACC_CALIBRATION       5, 5, 5, 5        ACC inflight calibration completed
11   ACC_CALIBRATION_FAIL  20, 15, 35, 5    ACC inflight calibration failed
12   READY_BEEP            4, 5, 4, 5, 8, 5, 15, 5, 8, 5, 4, 5, 4, 5    GPS locked and copter ready  
13   NULL                  multi beeps        Variable # of beeps (confirmation, GPS sat count, etc)
14   DISARM_REPEAT         0, 100, 10        Stick held in disarm position (after pause)
15   ARMED                 0, 245, 10, 5    Board is armed (after pause ; repeats until board is disarmed or throttle is increased)

These are in "On" "Off" duration (easiest to think of "long" "short").  Do you recognize the pattern that your beeper is making?  It might (or might not) lead somewhere.

4V is from powering the FC via USB. I tried powering the FC via LiPo, and have the same issue.

Thanks sloscotty, unfortunatley my buzzer sound doesn't coincide with any of the beeping schemes provided. Mine is a constant undisturbed high pitch beep that can only be disabled with Horizon mode on.

I'll try to create a new configuration, while avoiding configuring horizon mode and see if that helps. BTW, is there a way to export a profile's configuration to view in txt mode? Maybe even display an entire configuration in CLI?

Also, I suppose I can try a different buzzer. Could it be that the one I'm currently using is incompatible? During the startup sequence, everything sounds fine. I resolidered it from an old graphics card. I couldn't a datasheet for it online so I assumed it'll work.

I found how to dump the configuration. I put it up on google docs, hoping this may shed some light on what may be going on: link

Also, I'm wondering if setting angle mode may help? i.e. switch SH will toggle between Horizon and Angle mode. I'll give it a try when I have my FC at hand.

It turns out that this is a known problem. I see that your board is flashed with the REVO target. Flash it with the AIRBOTF4 target instead and your buzzer woes will be solved!

You are a genius, this helped and the constant beep has gone away!  

I flashed AirbotF4 with full FC erase enabled. Did the trick!

Excellent!

Thanks for coming back and letting us know. The next person who lands on this thread from a Google search will thank you.
