... The best library, I find, is timelib.h, the latest version is (seems to be!) by Paul Stoffregen ... I strongly disagree. Been there, done that... The Arduino timelib.h has been written for a blank Arduino and bases on millis() only. A kind of bare metal time library that is not even fully POSIX...

If you use the Arduino IDE, you have got the examples in File/Examples/ Examples for ESP32/ESP32 BLE Arduino...

(at their logical place, by the way)

Thank you, but what can I do with this information? esp_err_t esp_wifi_set_ps(WIFI_PS_MAX_MODEM); returns an error from the library: 'WIFI_PS_MAX_MODEM' was not declared in this scope. Does that mean that the library under ...\Arduino\Hardware\espressif\esp32\libraries\WiFi just makes no use of the ...

Thank you for replying I have currently 2 routines: I have slightly modified the routines; void reConnect() { WiFi.mode(WIFI_STA); WiFi.begin(); while (WiFi.status() != WL_CONNECTED) { delay(10); } } void disConnect() { // WiFi.disconnect(); //temporarily disconnect WiFi as it's no longer needed Wi...

Most questions in here can be answered by using a simple Google search... Most questions, maybe... But I could not find anything useful about the concrete syntax to enter into modem sleep, NOT light sleep, NOT deep sleep that are documented here https://docs.espressif.com/projects/esp-idf/en/latest...

Thank you for replying I have currently 2 routines: void disConnect() { // WiFi.disconnect(); //disconnect WiFi as it's no longer needed (this appear to remove the credentials) WiFi.mode(WIFI_OFF); btStop(); } void reConnect() { WiFi.mode(WIFI_AP); WiFi.begin(); delay(15); } When I run disConnect();...

You want to get a blazing fast sinus & cosinus generation without a lot of code?

Try that:
void setup() {
int X=0;
int Y=1000;
}

void loop() {
y1 = y1 - x1 / 16;
x1 = x1 + y1 / 16;
}

Unbelievable, but it generates a very nice and blazing fast sinus and cosinus on x and y!

Enjoy!

Hi, sorry to bother you, but I need some help. Call me stupid, but I just could not find any clear instructions on how to do that simple thing: enter and exit modem sleep for less than 1 second? I have been searching for hundreds of sites which all mainly go directly into light sleep or digressing p...
