GATT without bonding

[Paul]

How do I use the NRF51 or 52 to create a GATT server with read only service without requiring bonding? Basically I want to be able to provide more data than advertising allows. Another alternative that would work would be to allow a temporary bonding that did not require user interaction and would be forgotten when the connection was lost.

Thanks for your help

The Nordic Uart Service Server(NUS) example project will be a good starting point. It does not require pairing.

Alternatively, you can put data in both the advertisment packet and scan response packet. This will give you a total of 58 bytes. Then no connection is required.
