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.
