PAN1322-SPP Bluetooth Features
6.2.1
Secure Simple Pairing
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.
6.2.2
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 PAN1322-SPP start as slave, (Device B), the other device
can change it's own role making PAN1322-SPP master. The host controlling PAN1322-SPP will be notified with
the same event.
6.2.3
Sniff Mode
The local host or the remote device can request sniff mode for the link. During sniff mode, the devices synchronize
on sniff instants only. The module will enter low power mode in the sniff intervals, if allowed by the host LPM control
signals. Data packets can be exchanged at the sniff instants only, so the data rate is reduced in sniff mode. The
module will wake up the host when data is received or other responses need to be transmitted.
6.2.4
Sniff Subrating
The local host or the remote device can request Sniff Subrating for the link. When in sniff mode, the device will
automatically switch between Sniff Mode and Sniff Subrating Mode making it possible to stay longer in Low Power
Mode when there is no data transmitted or received.
6.2.5
Enhanced Power Control
PAN1322-SPP support Enhanced Power Control according to Bluetooth specification 3.0. The Enhanced Power
Control is handled automatically to make different modulations modes transmit on optimal levels.
