I want to set a pin to a BLE module, after it has connected to an android device.
I want to send the pin through android app, after I have connected to the ble device.
Please tell me how to set a pin to a ble module in arduino sketch.
If you could please share the code, it would be really helpful.
Thanks.

I want to set a pin to a BLE module

I really have no idea what that means.

I want to send the pin through android app

How do you expect the wireless connection to physically transfer a piece of hardware that you have somehow broken off? How do you expect to break that off using code?

What do you intend to do for your nest magic act?

If you could please share the code, it would be really helpful.

A miracle, you mean

In first run, I will automatically connect to the ble module in the arduino and send the new code, and in next connection, I will be required to enter the code I just set.

So, by pin, you REALLY mean PIN?
