Is it posible to generate passkey on some external device, and then update the BT-device (without MMi) automatically?
Hi,
Useally a BT device without MMI uses a fixed passkey. If this device is a public device, so that a group of people can connect to it, each person should have a unique passkey with the public device.
I wonder if it is possible with BlueZ to let some other external controll/system generate a unique passkey for each person that wishes to connect to this public device in the future.
The external controll/system updates the public device and sends the new passkey through a secure channel.
Is there some function in BLueZ for this? Is this be possible?

not really, but you can create a passkey agent that hands out different pin codes based on the remote device address.

I was thinking of setting up a couple of public BT-devices far away from each other. And hoping that a person could have the same passkey with all the public BT-devices. witch has no input og output capabilities)
This passkey agent that you talk about, was to be placed in the public device i suppose. Since a person has to use the same passkey with all the public BT-devices, I need some sentralized passkey agent.
I=B4ll have to think of some other idea of doing this...
