WebProblem: I need to retry at least 3 times (before giving up) to reconnect my NodeMCU if it doesn't get connected to Wifi, through deep sleep cycles in order to save batteries. I thought to use RTC memory to save a counter, but it doesn't work because content of RTC RAM is unpredicatble at first power up.

WebIn the later section of the tutorial, we will see how RTC is useful to wake up ESP8266 NodeMCU from a deep sleep cycle. Only the Real time clock (RTC) consumes power during the deep sleep mode and everything else is powered off. The ESP8266 has a built-in timer (RTC). Through the crystal oscillator in the module, the RTC keeps track of time. places to trek in uttarakhand
