Deep Sleep not work
Posted: Sat Dec 24, 2022 6:47 amHello, sorry for my bad English but I use a translator.
I am not a programmer, only a meteorology fan and I have built a small station to know temperature, humidity and pressure following this tutorial and it works perfectly although sometimes I have to press the Reset button several times to start, I think it is a board problem. I want to add solar panels and a battery but to save energy I want to add the option of Deep Sleep.
The problem is that it takes too long to connect to the wifi and does not give it time to send the data to Thingspeak so it goes back into Deep Sleep.
Could someone give me any advice or tell me that I am doing wrong?.
In case it served something, the board is this, CH340G
Thanks
