Vibration stand on nodemcu and 4 accelerometers

The project consists of an esp8266 nodemcu v3, which receives data via a tca9548a multiplexer from four adxl345 accelerometers, and transmits the data via wi-fi to the phone to display graphs of sensor positions. But the sketch doesn’t work, can someone tell me how to set it up?
