OTA not working (ESP32, IDE 1.8.19)

[nmi8080]

Hi.

I followed the tutorial at https://www.programmingelectronics.com/arduinoota/ and added the suggested code to my sketch.

I'm able to use WiFi to implement a TelnetStream stream, connect to the ESP32 and get debugging output. I set the IDE to use the correct network port for my board and try to upload a new sketch, but the upload (du-util 0.11-arduino4) errors out with "du-util: No DFU capable USB device available".

If I then connect the ESP32 with a USB cable and try the upload again, it works (even with the network port remaining selected).

The IDE clearly knows the network port is selected because if I try to open the serial monitor it errors out with "Serial monitor is not supported on network ports such as 192.168.86.47 for the null in this release".

Any ideas?

Thanks!

you don't use this ArduinoOTA library. you use the one bundled with the ESP32 platform
