Hi all!
In my application I would like to use LESC OOB pairing between two S132 SoftDevices. But there is one thing that I'm not sure of: I only have the (wired) OOB channel available before any BLE communication is happening.
My plan was to generate the OOB data at the central and send it to the peripheral over a wired interface. Some (long) time after the wired interface is disconnected I will set up the actual BLE connection, using the central's OOB data at the peripheral while using LESC OOB pairing.
But now my doubt's rising, is this actually possible? Or should I use LESC PassKey pairing? What would be the most secure way of establishing the connection in such a scenario?
