I opened projects in ESP-IDF for each of these examples. They built fine and I loaded them into ESP32s. When I run the code, though, I get most but not all of the output shown in the documentation. The two boards connect and the client will write to the server. The server, however, does not send its...

Thank you. #include <sys/time.h> worked.

I have found no mention of sys/time.h anywhere in ESP-IDF documentation or examples. Where should I have found this information?

ESP-IDF documentation says use settimeofday() to set the RTC.

"To stop smooth time adjustment and update the current time immediately, use the POSIX function settimeofday()."

When I compile IDE (VSC) says settimeofday() not declared. Is there a library I need?

Solved!!

SET_LOOP_TASK_STACK_SIZE( 16*1024 ); // 16KB
void setup() {

Thank you. I spent two weeks trying to crack this.

I am testing the use of the miniz library that is part of ESP32 Framework. This test should decompress the src_buf data and return uncomp_size = either -1 (failed) or 1440 (success). This sketch compiles on Arduino IDE 2.1.1 and loads to the board. When it runs, the ESP32 crashes with the messages b...
