Hello Edoardo,

do you have set the Boot Jumper on the ESC32?

And switch off: File -> Settings -> "Automatically reconnect last link..."


EDIT:
Can you connect your ESC32 via FTDI with your QGC 1.0.5 to change the parameter?

regards
florian

Hi Florian, thanks for answering.
Yes I did put the Boot Jumper and shorten the two pads. And the option "Automatically reconnect last link..." on Settings is off.
To answer the last question: No. That's another problem I have and I think is related to this one. If I go on "Esc32 Settings" and I try to connect the ESC nothing will happen. I'm not able to 'import' the parameters and thus not able to change them.

Are you sure that your com port works? please try to open the com port with a terminal und shorten the rx and tx pin of your FTDI. can you send chars and receive the echos?

I need to try, maybe it's just the com port.
I can't right now cause I don't have the board with me. I will try tomorrow morning and let you know.

I tried connecting rx and tx of the ftdi board and yes, if i type a character i do get the echo in return. So, that's working.
I also tried using putty to comunicate instead of QGC (to see if that was the problem) but the Esc is not responding. (e.g. if I try the command help or version I don't get any answer)

what kind of FTDI do you use? maybe you have to change rx and tx?
do you have testet it with another esc32?

sorry, but i have no more ideas.

The fact is I only have this one ESC right now, so unluckily I can't try with another one.
I'm doing this with my university and I am not building a drone for now (that's why I don't have 4 ESC like most of the people in this forum ). My goal is to modify the firmware and put a different control algorithm we want to try. But of course I can't if i'm not even able to flash the original one.
For next week I hope I'll find another Esc to test.
Anyway I'm using a Usb/Uart board like this one . The Ftdi on the board is a FT232RL.
What you mean for "change rx and tx"?
Anyway thank you for your help Florian, I also ran out of ideas. If you think of something else let me know, any other input is appreciated.

Hi Edoardo,
please give QGC 1.30 another try:
ftp://ftp.autoquad.org/3/334693_22529/g ... l/Windows/

You will need to connect Rx -> Tx and vice versa (as they stand for receive -> transmit).

Hi Norbert, thanks for answering.
My connections are already like this:
Rx -> Tx
Tx -> Rx
Vcc -> +5V
GND -> GND
(from Ftdi to Esc)
I can't try with the software right now because I don't have the board with me. Next week I'll give it a go.
