Help with ESC32 Communication via Serial Port

[fahdovski]

Hi all,

I cannot establish communication between my ESC32 and the qgroundControl.
I put
TX Ftdi to RX of ESC32
RX Ftdi to TX Esc32
5v and GND. I have a 3.3v FTDI version.
I was able to run the ESC32 with default firmware with a PWM servo signal.
But when i try to use qgroundcontrol for more in depth control of the ESC32, it connects but i do not have any feedback on parameters. I also cannot update the firmware even if i Put the boot jumper before. I always says that ESC32 is not in bootloader mode trying to force it... but I did connect the jumber.
I'm powering it with the UART for the signal.


Please need your help.
Thanks

Did you set 230000 baud rate ?
Try it via putty (or similar).

It works with the CLI correcly. I was able to change PWM.
For the Qgroundcontrol it does not works.
I was only able to update the firmware. But the other parameter does not change. Is there a Baudrate ??
Thx

Alright It works Greet. But I need the change the Speed but an error pop up and says that i need to set the Feed forward terms used for the RPM controller. What should i put as a value. How does it influence performance. Any tuto explaining the Feedforward PI Tuning
Thx

MN2204 + APC SF 8047 just for test.
But i need a more in depth procedure. For Example the Kiss ESC PWM freq is 32 Khz. I want to set Autoquad ESC32 to a switching freq of 32khz but how much blanking should i put ?

Magnificent Thx a lot. Can I increase the P term to say 0.4 to give more punch to the PI or is already perfectly tuned.
If I change the switching freq, i need to change the min period to 1/32Khz and the blanking to 60% of that value
since for example in the default setup we got Min period =50 and blanking =30 (60% of Min period).
Is this correct ?

as already said: I've never changed blanking!
