Description
I'm really not sure if this is by intention as it's a so obvious bug to me that i really wonder why no one else has stumbled over it, but
according to file Esp.cpp:
void EspClass::deepSleep(uint32_t time_us)
{
esp_deep_sleep(time_us);
}
Where esp_deep_sleep expects a uint64_t value (which makes much more sense, as the 32bit value limits sleep time to ~4300 seconds).
Sketch
uint32_t SleepTime = (7200 * 1000 * 1000); //µs -> overflow!
ESP.deepSleep(SleepTime); // -> actual sleep time ~2900secDebug Message
