How did you configure them? You may need to do an gpio_reset_pin() on the GPIO to get them out of JTAG mode.

It was just with gpio_set_direction.

But gpio_reset_pin solved everything. Thanks a lot!

According to documentation, GPIO_39, GPIO_40, GPIO_41, GPIO_42 are occupied for JTAG and can't be used as GPIOs (e.g. in OUTPUT mode for push/pull operations).


You are correct in that these are the JTAG pin, but mistaken in that they are occupied like this by default (by default, the USB32-S3 ...

Hi.

I'm working with esp32-s3 devkit N32R8V version:

Hi, i had a same problem as described above, so i've managed with it by setting buffer size of client large enough, By default it will be just 512 bytes
esp_http_client_config_t config = {};
config.url = reqInfo.url.c_str();
config.is_async = false;
config.timeout_ms = reqInfo.timeoutMs;
config ...
