In my testing, TCP socket maximum throughput was 12Mbps~15Mbps. you can see the testing codes from here -> http://www.esp32.com/viewtopic.php?f=13&t=839 .

UDP socket maximum throughput was 35~40Mbps between two ESP32 module(The same as above link testing configuration).

However, ESP32's ...

Hi, kolban.

In my application (the last posting -> http://www.esp32.com/viewtopic.php?f=13&t=839 ),
I need to speed up the TCP socket throughput between two ESP32 modules.
Now I trying to adjust the socket buffer size. I guess that the maximum throughput is affected by the buffser size.
I can ...

Hi,

In order to get the socket buffer size, My codes call the function getsockopt() .

However, the return value is always -1, and the err msg is "Protocol not available".

the codes I used,
ESP-IDF version 1;

void Init_Client_mySocket(void)
{
struct sockaddr_in serverAddress;
memset ...

Hi,
I measured the ESP32's tcp socket communication maximum throughput, the maximum speed I achieved is 10Mbit/sec only.

I hope that ESP32's tcp socket is more faster than 10Mbps.
above 10Mbps available in ESP32? If then, please help how can I speed up.
