Class 2 Bluetooth module - F2M03C2
Datasheet
5.5
RFCOMM Stack
In this firmware version the upper layers of the Bluetooth stack up to RFCOMM are run onboard the
module. This reduces host-side software and hardware requirements at the expense of some of the power
and flexibility of the HCI only stack.

Architecture
The RFCOMM firmware exposes APIs (application programming interface) to L2CAP, Service Discovery
Protocol (SDP), RFCOMM and Device Manager (DM) functionality. Background information on Bluetooth
and its upper layers can be found in the Bluetooth specification v1.1. The firmware also contains a Virtual
Machine (VM), which may be used to develop customer applications on the module.
Two variants of this firmware are provided; one supports the BlueCore Serial Protocol (BCSP) transport
protocol and the other supports the Bluetooth UART (Universal Asynchronous Receiver Transmitter) H4
protocol.
Note:
RFCOMM firmware does not expose the Host Controller Interface (HCI) and is, therefore, not suitable for
use with third party stacks.
