In Betaflight you get 3 beeps after powering up the quad once the Gyro has detected no movement and has been able to successfully calibrate itself (i.e. before you take of). The pattern of the beeps is 20ms ON then 10ms OFF repeated 3 times. So beep, beep, beep.

The "ready" beep when a GPS fix has been acquired (before arming) gives 6 beeps in the pattern of 4ms ON then 5ms OFF repeated twice, then 8ms ON then 5ms OFF, then 15ms ON then 5ms OFF, then 4ms ON then 5ms OFF repeated twice. So it's quite a fancy pattern of short beep, short beep, medium beep, long beep, short beep, short beep.

With GPS enabled, trying to arming when there is a GPS fix give 4 beeps in the pattern of 5ms ON, 5ms OFF, 15ms ON, 5ms OFF repeated twice. So short beep, long beep, short beep, long beep.

With GPS enabled, trying to arm when there is no GPS fix gives 3 beeps in the pattern of 30ms ON then 5ms OFF repeated 3 times (so longer beeps with a shorter pause between each compared to the gyro calibration confirmation beeps). So beep, beep, beep.

Thanks for that, I was looking around for that type of explanation but no luck. Your a wizard lol! also the 3 beeps did not happen when I first powered up the quad. It happened after about 10 minutes of the quad being plugged and powered in betaflight trying to locate the gps fix.

You can select low power VTX before 1st arm. This ensures on first power up whilst you wait for GPS its only 25mw It then goes up when you arm. You can also configure pit mode on a switch off course.
