I'm using the same code from here :
I start BLE advertising and GattServer. I added my read & write characteristics. Everything works but when a client(nRF Connect - Android Application) tries to connect it asks for pairing / bonding. I don't want the need of pairing/bonding. Client should directly connect.
I can connect other devices without pairing/bonding by using same app(nRF Connect - Android Application).
How can I disable the need of pairing/bonding in my Ble advertisement / Gatt server?
