Multiple passkeys

[Dani]

Good morning, I have already implemented my application based on nRF51822 and SD110 v8. In what regards bonding, I use a static passkey and it works fine. The product has an initially set passkey and the final user will be allowed to change it. Nevertheless, and as a manufacturer, I would like to have the possibility to also bond this module whenever. I have in mind different procedures to implement this. But the easiest one would be to have the possibility to register two or three different passkeys for the module itself. So, it would be allowed to bond this device by using two or three diferent codes. Is that possible? Best regards.

The end user only have to know one passkey. The other(s) one should be only for technical support purposes. So only one has to be active at a time. The main purpose is that it should be possible for us (as manufacturer) to bond any device: final user can send us back his module for updates/upgrades/reparations, and we would like to bond the device without changing the passkey that the final user has defined.
