I've been trying to get BLHeli suite to work for my BLHeli_s ESCs, but every time I try to make a 4-way interface for my Arduino R4 WiFi it gives me the error message "Avrdude FAILED! stk_500getsync(): not in sync: resp=0x00".
In my IDE software when I upload the basic sketch it works, I selected COM3 and Arduino R4 WiFi board in there. When using COM3 and selecting the Uno w/ Atmega328 for board, keeping the baud on 115200 and using either the 4wArduino_m328p*16*.hex or 4wArduino_m328P_16_PB3PB4v20006.hex it gives me this error code no matter what. I've tried it with both one ESC connected and disconnected, but I'm pretty sure this shouldn't matter as im trying to get my Arduino interface up and running, the ESCs aren't involved yet. I've also installed the CSP210x driver for Windows and the STM VCP USB driver even though it only gave a Windows 8 option, whereas im in Windows 10. Any ideas?
PS: I'm a newbie when it comes to Arduino, so the answer might be super obvious
An Arduino Uno R4 is not an Uno. Seeing 328P in the filenames makes me suspect that it will never work; the R4 uses a totally different processor. You'll need to find hex files compiled for for the Arduino Uno R4, not for the Uno.
To my knowledge (because of the different processor), uploading to the Arduino does not involve avrdude so that's the next problem that you have to solve.
Did you install the board package for the Arduino Uno R4?
I haven’t been able to find any board package for the R4, let alone hex files. Hex files could maybe be made but I don’t see how I’d get the board package so I can select it in the list of boards.
My guess is the R4 is too new for the BLHeli software, which by now is about 10 years old. No one has used BLHeli suite with the R4 as far as I can find on the web, so this might be a doomed attempt.
The only option I luckily have left is loaning a different Arduino board which is compatible, I only need to readout the start and stop values of my ESCs so I don’t blow them up or so I’m not unable to control them. Thank you for clearing matters up for me.
