5.2.1 Secure Simple Paining
The device implements Secure Simple Pairing with the following association models
according to BT2.1 core specification:
• Numeric Comparisoon
•Just Works
• Passkey Entry
Also pairing with legacy (BT2.0 and older) devices is supported.
5.2.2 Role Switch
The initiating device (devA) starts as Bluetooth master of the link, the accepting device
starts as Bluetooth slave of the link. The remote device can request a role change to
accomodate with other Bluetooth links. If that happens, the module will send an event
to the host. Also if the eUniStone start as slave, (Device B), the other device can
change it's own role making eUniStone master. The host controlling eUniStone will be
notified with the same event.
