Hallo.
I am at my first RC build and I am stuck in despair, after days of trying everything. I hope some of you can save me and push me out of this depressive situation...
I am unable to calibrate the ESC using Betaflight Configurator nor to control the motors via transmitter.
After connecting the FC to a PC via usb, connecting Betaflight configurator to the FC, turning the transmitter on (already bound to the receiver), bringing all motor sliders to the maximum, when I connect the battery to the quad, I hear 3 short beeps of ascending tone followed by a long beep of low tone, then silence. Moving sliders produces no effect on motors nor in the horizontal bars of the receiver section of betaflight configurator. After reconnecting the battery, the gimbles still have no effect on the motors.
What could be the problem? Can you please suggest ways to diagnose and debug?
Thank you!
Cheers

Note that:
- I calibrated the ESC manually, one by one using another receiver (X8R frsky), hearing the correct tones and being able to control the motors via the transmitter without FC. So I think there is no issue with the ESCs.
- This happens also with another identical new FC.
- Betaflight configurator does not change the horizontal bars in the receiver section when I move the gimbles.
- I see the same behaviour with frsky x8r. Additionally in this case betaflight configurator shows 0 in all horizontal bars of the receiver.
- The parts are:
- ESC: OCDAY 20A oneshot125 (with stock firmware)
- FC: SPRACING F3 DELUXE (with Betaflight / SPRACINGF3 3.1.7 Apr 3 2017)
- RX: FrSky XSR (with stock firmware)
- TX: FrSky Taranis Qx7 (with stock firmware) in Mode2
- PDB: Matek Mini Power Hub
- MOTORS: Emax RS2205 2300KV
- I configured Betaflight Configurator only with:
- UART3 with Serial RX
- serial based receiver
- SBUS
- oneshot125 esc protocol
