hello, i am planning to use esp in my project for one way communication to send a char when button is pressed from the transmitter module to the receiver base where is gets the chat and based on it's value it will trigger some relays.
i've documented and come up with some questions that i would appreciate some help in understanding;
First for those who used the module before, did u experienced the module resetting when not needed caused by floating rst pin - wich a resistor from 3.3v to rst i've heard it would help, rf interference, or watchdog triggering and how to handle it, power supply spikes causing reset, would capacitors help and 13Ah phone battery pack would work?
Also the tx send only when button is pressed but the rest of the time it keeps looking for the button pin state, should i add a delay to lower the loop repetition ?
And on the rx side should it keep watching continuously for the signal from the tx or also it should have a delay, if the signal reach when the module is waiting in the delay it will still be received ?
after some testing, i've send a signal every 1sec and received then, light and led ,wait 1 sec delay and check again, some signals were missing . with 10ms delay it got the led blinking regulated but the wifi transmitter module metal part got a bit hot
