Important points:
1. The Network ID and BAND should be the same for the transmitter and receiving end Lora module.
2. Set the BAND as per the eligible LoRa bands in your country.
3. You can use any other microcontroller for this Lora project.
4. All the AT commands for configuring the LoRa module are written in the void setup() function of the source code.
5. The range for this LoRa project will be up to 5KM in rural areas. (Range will decrease if the number of obstacles increases in the signal path).
6. After the restart you have to wait till the STATUS LED turns OFF.
7. Please watch the complete video, otherwise you may face some issues.
**Please take proper safety precautions while working with high voltages.


During this Lora tutorial video, I have explained all the required information to make this LoRa project. You can use any microcontroller with the LoRa module. Both the microcontroller and LoRa module communicate through the serial terminal at the 3.3V logic level.
The range for this LoRa module is up to 10KM, So this project is very useful in rural are where WiFi is not available. The range may decrease in urban areas due to more obstacles in the path.
