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 band in your country.
3. You can use any other microcontroller in receiving circuit.
4. During reset and programming NodeMCU remove the LoRA module. Connect the LoRa module after giving the supply.
**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.
