Hello,

I use the web server from sprite on an esp32 with html and javascript files to get data to the browser with ajax as
you described it.

Good point ! I agree the chip should not be working at 140 C. The esp32 chip is shielded in a metal housing. You will not feel the heat produced in the die on the metal housing and that metal part, which seem not to be attached to the thermal pad, already gets warm. I am reading these values with th...

The frequency can be set in the makefile configuration "make menuconfig->Component config->Esp32-specific->cpu frequency".
It should be the core frequency. Changing it from 240 MHz to 80 MHz has an effect on the temperature. The temp 140 reading goes down to about 125 ...

Hello,

most probable it is related to the USB cable connection. Try using higher quality cable. It could also be observed when the current/voltage is at a limit.

Hello, To get the thermal pad connected, I used one of the standard adapter boards from ali e.g. https://www.aliexpress.com/item/5Pcs-ESP-32S-Pinboard-Convertor-Module-ESP32S-Adapter-Board-Support-for-ESP-32S-Wireless-WIFI-Bluetooth/32791251250.html?spm=2114.01010208.3.178.bnub8x&. Then drilled a 1....

I have tested both cases. If the thermal pad is connected (by soldering) to the pcb, I read about 62 (probably this means 62 degree celsius) from the internal temp sensor. If the thermal pad is not connected to the pcb, as it seems is the case for the development boards I got so far from aliexpress,...

Hello, After experiencing unreliable TCP access (esp-idf 2.0), checking the code there seem to be some inconsistency. lwip/opt.h: here we define #define TCP_LISTEN_BACKLOG 1 in tcp.c: void tcp_pcb_purge(struct tcp_pcb *pcb) ....... if (pcb->state == SYN_RCVD) ... in tcp_in.c: static err_t tcp_proces...
