rev: c extended range bluetooth ? module - f2m03gx /gxa datasheet 5 firmware versions f2m03 is supplied with bluetooth stack firmware, which runs on the internal risc micro controller of the bluetooth module. this chapter includes an overview of the different opti ons for more in depth information please use separate firmware dat asheets provided by free2move. all firmware versions are compliant with the bluetoot h specification v2.0. the f2m03 software architecture allows bluetooth processing to be shared between the internal micro controller and a host processor. depending on application the upper layers of the bluetoo th stack (above hci) can execute on-chip or on the host processor. running the upper stack on f2m03 module reduces (or elim inates, in the case of a on module application) the need for host-side software and processing time. the integration approach depends on the type of produc t being developed. for example, performance will depend on the integration approach adopted. in general fr ee2move offers four categories of bluetooth st ack f i rmware: ? wireless uart; offers a transparent interface to the bluetooth channel. there is no need for additional drivers or bluetooth software on the host. ? embedded module solutions offer an application to run on the module. there is no need for an external host (e.g. a bluetooth headset). ? two-processor solution involving a host and host c ontroller, where the higher layers of the bluetooth stack has to be implemented on the host. ? two-processor embedded solution offers a host with limited resources to gain access to a bluetooth stack, with the higher layers on-chip, via a special api. the protocol layer models for the different bluetoot h stack firmware categories can be represented as shown in the figures below. hardware baseband and rf application interface hci link manager l2cap device manager rfcomm sdp wireless uart application (spp) f2m03 host application hardware baseband and rf application interface hci link manager l2cap device manager rfcomm sdp application f2m03 host w i reless uart embedded single- processor architecture ? 2006 f r ee2move ab page 9(47)

rev: c extended range bluetooth ? module - f2m03gx /gxa datasheet 5.1.2 settings the default settings allow the user to communicate via bluetooth, without sending any configuration commands, as soon as a successful connection has been established. information sent and received on the serial interface of the wu unit at 38400 bps is transmitted transparently between the two connected devices. the default settings are valid as long as the user has made no configuration. when there is no bluetooth connection established it is possible to configure the wu firmware via commands sent on the serial interface. all settings changed by the user are stored in persistent memory. the following serial settings are used for c onfiguration mode and are not configurable: parameter default value baud rate 38400 data bits 8 parity none stop bits 1 hardw a re flow control on to be able to send commands to the wireless uart firmware, it must be set in host controlled mode (hcm). as previously described the wireless uart firmware can only enter hcm when no bluetooth connection is established. once entered hcm there are several commands that can be issued: ? configuration commands ? software / hardware reboot ? inquiry (search for bluetoot h devices in the neighborhood) ? pairing (device security - authentication and encryption) ? advanced configuration commands ? sco commands ? information commands ? control commands configuration commands there are several settings stored in the wireless uart firmware that can be read and modified by using the configuration commands. examples of these settings are: ? local bluetooth name ? local sdp-service name ? operating mode ? serial port settings ? bluetooth security settings ( authentication, encryption) there are two normal operating modes: ? connecting mode ? bluetooth master ? endpoint mode ? bluetooth slave in connecting mode the wireless uart firmware will conti nuously try to establish a bluetooth connection to a specified remote bluetooth device in the neighborhood (bluetooth master). in endpoint mode the wireless uart firmware may acc ept connections from remote bluetooth devices. a connection request will be accepted when the specif ied rules are fulfilled (bluetooth slave). ? 2006 f r ee2move ab page 13(47)
rev: c extended range bluetooth ? module - f2m03gx /gxa datasheet software / hardware reboot this option gives the ability to be able to reboot the module via software commands. inquiry search for other bluetooth devices in the neighborhood. there are three configuration parameters: ? how many seconds the search should be active ? a filter, used when searching for devices of as certain class ? the possibility to include the bluetoot h name of the discovered devices pairing when authentication is enabled, the devices must be paired before a successful connection can be established. the wireless uart firmware can either initiate pairi ng with a remote device or accept pairing requests. during a pairing pin codes are exchanged between the local and remote device. a successful pairing requires identical pin codes. the resu lt of the pairing attempt will be returned to the host. if pairing was successful, a unique link key has been generated and saved in non-volatile memory. the link key is used in the connection establishment procedure for secure ve rification of the relationship between the paired devices. the wireless uart firmware allows the user to be paired with one device at a time. the last pin code entered and link key generated are saved. advanced configuration includes among others commands for enabling power save modes, fine tune performance, enabling modem emulation and changing transmit power. sco commands makes it possible to establish full dupl ex audio connections between two wu units. ? 2006 f r ee2move ab page 14(47)

rev: c extended range bluetooth ? module - f2m03gx /gxa datasheet 6.2 usb interface f2m03 contain a full-speed (12mbits/s) usb interface, capable of driving a usb cable directly. no external usb transceiver is required. the device operates as a usb peripheral, responding to requests from a master host controller such as a pc. both the o hci and the uhci standards ar e supported. the set of usb endpoints implemented behave as specified in t he usb section of the bluetooth specification v2.0+edr. as usb is a master-slave orientated system, f2m03 only supports usb slave operation. note: the usb interface can only be used with the hci firmware 6.2.1 usb data connections the usb data lines emerge as pins usb_dp (u sb +) and usb_dn (usb -) on the package. these terminals are connected to the internal usb i/o buffers of f2m03 and therefore have low output impedance. to match the connection to the characterist ic impedance of the usb cable, series resistors must be connected to both usb + and usb -. 6.2.2 usb pull-up resistor f2m03 features an internal usb pull-up resistor. this pulls the usb_dp pin weakly high when f2m03 is ready to enumerate. it signals to the pc that it is a full-speed (12mbit/s) usb device. the usb internal pull-up is implemented as a current source, and is compliant with 7.1.5 of the usb specification v1.1. the internal pull-up pulls usb dp high to at least 2.8v when loaded with a 15k ? -5% pull-down resistor (in the hub/host) (when vdd=3.1v). this presents a thev enin resistance to the host of at least 900 ? . alternatively, an external 1.5k ? pull-up resistor can be placed between a pio line and d+ on the usb cable. the default setting for the hci-f irmware uses the internal pull-up resistor. 6.2.3 power supply the minimum output high voltage for usb data lines is 2. 8v. to safely meet the usb specification, the voltage on terminals must be an absolute minimum of 3.1v. free2move recommends 3.3v for optimal usb signal quality. 6.2.4 self-powered mode in self-powered mode, the circuit is powered from it s own power supply and not from the vbus (5v) line of the usb cable. it draws only a small leakage current (bel ow 0.5ma) from vbus on the usb cable. this is the easier mode for which to design for, as the design is not limited by the power that can be drawn from the usb hub or root port. however, it requires that vbus be connected to f2m03 via a resistor network (rvb1 and rvb2), so f2m03 can detect when vbus is powered up. f2m03 will not pull usb + high when vbus is off. pi o us b + us b ? pi o[ 2] ( u sb on ) connections to f 2 m03 for self-pow ered mode the terminal marked usb on is default pio[2] in the standard hci-firmw are. ? 2006 f r ee2move ab page 21(47)
rev: c extended range bluetooth ? module - f2m03gx /gxa datasheet 6.2.5 bus-powered mode in bus-powered mode the application circuit draws its current from the 5v vbus supply on the usb cable. f2m03 negotiates with the pc during the usb enumer ation stage about power consumption. bus-powered mode is not supported in the defaul t firmware of the hci-firmware when selecting a regulator, be aware that vbus may go as low as 4.4v. the inrush current (when charging reservoir and supply decoupling capacitors) is limited by the usb specification (see usb 1.1 specification, section 7.2.4.1). some applications may require soft-star t circuitry to limit inrush current if more than 10f is present between vbus and gnd. the 5v vbus line emerging from a pc is often electrically noisy. regula tion down to e.g. vdd=3.3v should include careful filtering of the 5v line to attenuate noise that is above the voltage regulator?s bandwidth. excessive noise on the vdd supply pins of f2m03 may re sult in reduced receive sensitivity and a distorted transmit signal. recommended voltage regulator for the f2m03 is presented in section 6.7 . us b + us b ? usb o n connections to f 2 m03 for bus-pow e red mode identifier value func tion r s 27 ? nominal impedance matching to usb cable r vb 1 22k ? -5% vbus o n sense divider r vb 2 47k ? - 5% vbus o n sense divider usb interface component values note: usb on is shared with f2m03?s pio terminals . ? 2006 f r ee2move ab page 22(47)
rev: c extended range bluetooth ? module - f2m03gx /gxa datasheet 6.2.6 suspend current usb devices that run off vbus must be able to enter a suspended state, whereby they consume less that 0.5ma from vbus. the voltage regulator circuit itself should draw only a small quiescent current (typically less than 100a) to ensure adherence to the suspend-current requirement of the usb specification. this is not normally a problem with modern regulators. the entir e circuit must be able to enter the suspend mode. 6.2.7 detach and wake_up signalling f2m03 can provide out-of-band signalling to a host contro ller by using the dedicated control lines called usb_detach and usb_wake_up. these are outside the usb specification (no wires exist for them inside the usb cable), but can be useful when embedding f2m03 into a circuit where no external usb is visible to the user. both control lines are shared wi th pio pins and can be assigned to any pio pin by firmware settings (contact free2move) usb_detach, is an input which, w hen asserted high, causes f2m03 to put usb- and usb+ in a high- impedance state and turns off the pull-up resistor on u sb+. this detaches the dev ice from the bus and is logically equivalent to unplugging the device. when usb_detach is taken low, f2m03 will connect back to usb and await enumeration by the usb host. usb_wake_up, is an active high output (used only when usb_detach is active) to wake up the host and allow usb communication to recommence. it repl aces the function of the software usb wake_up message (which runs over the usb cable proper), and cannot be sent while f2m03 is effectively disconnected from the bus. usb_det a ch and usb_wake_up signal 6.2.8 usb driver a usb bluetooth device driver is r equired to provide a software interface between f2m03 and bluetooth applications running on the host. fr ee2move don?t supply this driver. ? 2006 f r ee2move ab page 23(47)
