Hello, I am using an esp32s3 and making an HTTP CLIENT call using the streaming method (esp_http_client_init,...open, write, etc...). Sometimes when I call "esp_http_client_write" I see the error below: transport_base: Poll timeout or error, errno=Success, fd=54, timeout_ms=25000 Questions: 1. What ...

Yes, I did solve it. The end answer for my board was the power was unstable and that was only seen at the network connection. The other things that helped mitigate it before we fixed the power stability were: Changing TX power (re:https://github.com/espressif/arduino-esp32/issues/6767) Changing to a...

Thank you, that does make sense. I want to understand why though. It's a Google website so the DNS is fine. Also, it works from my ESP32S3 about half the time. (From the same location, same wifi AP, etc...).

Thanks,

Hi, I have a custom board with an ESP32S3 WROOM module on it. Running wifi code I intermittently get this error: esp-tls: couldn't get hostname for :<<website>>: getaddrinfo() returns 202, addrinfo=0x0 esp-tls: Failed to open new connection transport_base: Failed to open a new connection HTTP_CLIENT...

Thanks! I don't see any other code that would be grabbing the bytes. I added code to get the size of the available bytes inside the event before I attempt to uart_read_bytes. uart_get_buffered_data_len(UART_PORT_NUM, &bytesReady); And bytesReady is 1 byte less than the event.size. I'm not sure why t...

I'm using the ESP IDF UART driver. I receive an event with event.size=9 bytes (for example). Then I try to uart_read_bytes for 9 bytes and the code still takes 1000ms sometimes. Is this expected? I would assume that once the event is there and has the number of bytes, those bytes would be ready in t...

Thanks for the thorough and quick response! I'll look for some workaround for what I'm doing.

Hello, When compiling the simple program below with a macro as a case label, I receive the error: case label does not reduce to an integer constant The error only happens with the xtensa-esp32s3-elf-gcc compiler. This does not happen with plain gcc. #include <stdio.h> // #include <stdlib.h> #include...

Hello, On an ESP32 I have a SPIFFS mounted as a VFS. I have two FreeRTOS tasks: task A, and task B. Task A is writing to File A (fwrite) Task B is writing to File B (fwrite) If they both are trying to write simultaneously does the SPI or VFS driver handle it or do I need to implement some type of mu...

Thanks! I'll check it out.
