I don't have a PICO-D4 to test on, but I am unable to reproduce on standard esp32. Please set core debug level to verbose and post the log (the stuff...

Does it work if you use ets_printf instead?

From TTN_esp32 on github: > This repository is archived. Please use [EzLoRaWAN](https://github.com/rgot-org/EzLoRaWAN) for now. The new library can use SX127X and SX126X chips.

As Erol444 noted, that library is in ESP-IDF, not arduino-esp32. The example is at https://github.com/espressif/esp-idf/tree/master/examples/peripherals/spi_slave

See the line that says `#include "camera_pins.h"? That defines the camera pins. Your board is then shown at https://github.com/espressif/arduino-esp32/blob/master/libraries/ESP32/examples/Camera/CameraWebServer/camera_pins.h#L268-L295

For troubleshooting, make a direct connection from the computer to the esp32. Once you know it is working, you can test through the hub, using the other ports, etc.

We do not support 3rd party libraries here. v2->v3 was a major, breaking API change. The library author will need to update the library to support the new API.
