Все ПРИ возврате команд терпят неудачу

Я пытаюсь отправить данные с датчика на ThingSpeak, но команды AT всегда возвращают сбой. Они иногда работают и посылают данные. Но в большинстве случаев они возвращаются.

Мои Связи:

Мой код:

#include <LiquidCrystal_I2C.h>

#define SensorPin 0          // аналоговый выход pH-метра подключен к аналогу Arduino

#define ONE_WIRE_BUS 8

А вот последовательный выход монитора:
