Hi,
I am new to nRF5x BLE devices.
I need to create a project and would like you to help me out.
I need to connect two nRF51822 devices. If one of the devices goes away from the proximity (5m) one of it beeps with a buzzer. (No app control required)
Just like a car key fob. If you take the key 5m away from the car it should beep.
How can I do this?
-
Can I use arduino IDE for this?
-
what is the easiest way to program it?
-
How do I code it?
- One will advertise/transmit data/location.
- The other module will keep on checking the distance and if the distance exceeds 5m (signal strength, db etc) it should beep.
I clearly have no idea, please help.
