Connection problem of ESP8266 ESP-01 arduino uno to cayenne - arduino

Question

I am using the ESP8266 Wi-Fi shield to connect Arduino to the cayenne server. However once connect the chip to the access point it will heat up and sometimes will lagging. After that, it shows some message but the Cayenne server didn't connect to the Arduino. Every widget can not be operated (No response when clicking a button, temperature value unchanged, etc.). Can anyone solve this issue? It is important for my course work. I am using Arduino Uno and ESP8266 ESP-01 chip. We have tried different styles of code to upload data to cayenne server but they didn't work(Below include 3 versions)

Answer 1

If your module is getting warm its probably a hardwareissue.I guess you use 5V for the esp module which is bad as it only needs 3.3V. It might survive 5V for a short time(moment) but don't stretch your luck. So you have to convert 5V ro 3.3V level shifter. You can not use the Arduino 3.3V output pin because it can not provide the power needed by the ESP (up to 250mA) vs. max 50mA on the Arduino (UNO) 3.3V pin.
The schematic shortly explained:
The ESP's VCC pin is powered by the 3.3V output pin of the voltage regulator (AMS1117 in the grphic).
The 10uF capacitor is connected to the output pins to stabilize the regulator.
The CH_PD pin must also be connected to 3.3V.
The GND pin is obviously connected to ground.
The ESP's TXD pin can be connected directly to the RX pin of Arduino (emulated on pin 6).
The ESP's RXD pin is connected to the TX pin of Arduino (emulated on pin 7) through the level shifter.
The last two can be changed depending if you use hardware or software serial EDIT
As you use rtc it makes no sense to update the time every loop this will crash your connection. Either do it every x hours and make sure with if/else that nochyenne loop() is running. It makes no sense to sync time every x millis() the syncing of time every hourisenough foryour scenario, I would go for once a day
