I have two lora and two arudino and bluetooth i need to turn led on and off with help of an bluetooth mobile app please any one send me circuit and code for this im an beginner
The objective of these forums is not for the voluteers in here to produce or write code on demand.
Most Libraries include examples within them that demonstrate how to do stuff and there is a LoRa library that has working code for turning remote devices, LEDs etc, on or off.
But you have not explained in any way why such an example needs the 'help' of Bluetooth, or why you want\need to use LoRa at all.
The search phrase "arduino android bluetooth control" will turn up lots of tutorials.
Thank you for the reply im sorry for asking the code. I will look into the examples.i use lora because it has range of 450 to 1000 m and i using it to control the irrigation motor by mobile with bluetooth to communicate wih lora.And this bluetooth controlled led is for understanding purposes there is no youtube vedio for this lora to lora communication with bluetooth to connect with mobile.
The range does depend entirely on the location and its environment. In a dense urban area for instance you might not even get the 450m.
There are plenty of tutorials on using LoRa radios with Arduino. Follow one, get the setup working, then check at the actual site whether you still have communication.
Clear line of sight between transmitter and receiver is generally required.
