If you aren't getting anything on the LCD display, or some other issue seems to have shown up, there are a few things you can check. Let's start by connecting the transmitting board (with the Environmental Sensor) to your computer with a USB cable, then opening up the Serial Monitor window. If the sensor is working properly and the WiFi module is sending the package, you should see something like this in the Serial Monitor:

Temperature in Fahrenheit: 74.46
Humidity: 22.21
Pressure: 84992.97
Sent with success

If the receiver isn't powered up, you'll also see:

Last Packet Send Status: Delivery Fail

If all is as it should be here, you can connect connect the receiving ESP32 to your computer, power up the transmitter with a battery or power supply, and check the results there. The Serial Monitor should be displaying the temperature, humidity, and pressure readings. If you're still having issues, reach out to our support team.
