Setting Link Level Security Mode

Setting Link Level Security Mode

[Randy Yates]

We have a requirement to set Link Level Security mode 1. How can this be
done with the bluez stack?

The mgmt-api allows the following bit-mapped modes to be 
configured:

		1	Powered
		2	Connectable
		3	Fast Connectable
		4	Discoverable
		5	Pairable
		6	Link Level Security (Sec. mode 3)
		7	Secure Simple Pairing
		8	Basic Rate/Enhanced Data Rate
		9	High Speed
		10	Low Energy

Note that although you can set Link Level Security mode 3 on or off,
there is no general way to set the link level security mode, which
according to Huang's "Bluetooth Essentials for Programmer" (p.31)
consists of three different modes (mode 1, mode 2, and mode 3).

Hi Randy,

As far I can understand you security mode is has been removed from
specification since Bluetooth 2.1, it is mandatory to encrypt link
before service level connection.
