ESP32-S2 slow transfer

[piotr-go]

Hi
I have 19Mb/s transfer speed on ESP32 and ESP32-C6 but only 4Mb/s on ESP32-S2.
I suspect not enough RAM may be a problem. Can you enable PSRAM support for S2 ?

Soft: 7.1.1

Thank You

Hello,

unfortunately I can't do that. I try to keep the code base as general as possible and ignore specifics for individual devices.
Sorry, it's not worth it and it's also extremely time consuming to support several devices and configurations when you can simply buy another (fully supported) chip for €3. I hope you understand that.

Kind Regards,
Danny

From what I remember, you can set autodetection of PSRAM in the config.

Can you tell me why my esp32 c6 can only do 2mbps, is there any setting that need to be adjusted, and it's only wifi 4, no wifi 6

My ESP32-C6 module: ESP32-C6-WROOM-1-N8
From: https://pl.aliexpress.com/item/1005006271962503.html
I only set ssid and password.

My AP: MikroTik RB952Ui-5ac2nD

source router is wifi6 and can do 100m
my module is ESP32-C6-WROOM-1-N4

do your register as wifi6 ap to client?

[piotr-go]

Unfortunately my AP is only Wi-Fi 4.
I don't have Wi-Fi 6 AP to test.

do your phone see repeater as wifi4 or wifi6

Phone also wi-fi 4, but i have wi-fi 6 (RTL8852BE) in my PC.
