Is it possible to connect without using GATT ?

Is it possible to receive connections without setting up a GATT service

For security reasons, I would prefer if generic apps and also the new Web BLE API could make connections to my BLE device.

I would prefer to just advertise a service and handle the connections at a lower level using a custom protocol

Is this possible using S130 SD2.0.1 (SDK 12.0.1) nRF51822 ?

Petter,

Thanks for the suggestions.

We have a accelerometer and also a button (in some optional configurations).

I think the best solution may be to change the advertising data after a connection has been made, so that the device is not connectable for a suitable period, e.g. 15 minutes or perhaps an hour.

As in normal operation, the device would only be connected to quite infrequently e.g. once per week to make changes to its configuration.
