Q1> Should I use all the signals of the BCD100 when the SPP firmware is used?

Ans> If the SPP firmware is running on the BCD100, you can connect only following signals and let the rest open.

Following circuit shows BCD100 module interface.

Q2> How to select L,C1,C2 values of the antenna circuit?

Ans> You need to select L,C1,C2 values based on your antennal characteristics.

For the ESD100v2, 0 resistance is connected to L and the antenna connector is connected directly.

When an embedded chip antenna is used, C1,C2 can be used for antenna matching. For the ESD100v2, this is not connected.

If you use a connector to use an external antenna, you can connect directly to RF I/O. (Refer to following circuit)

Q3> Can I use the BCD100 to make a USB Bluetooth dongle?

Ans> Optionally, the BCD100 can be supplied with only software stack up to HCI level instead of the standard SPP firmware so users can develop and embed their own firmware version into the BCD100 or entire Bluetooth stack runs on the host side for the application such as USB dongle for computers.

In this case, you must request the firmware for HCI interface.

Following is the sample circuit for the USB interface.

Q4> How can I configure the default operation mode of the SPP firmware?

Ans> The default operation mode of the BCD100 is MODE0. In this mode, the BCD100 is waiting for user AT commands. Other Bluetooth device can not search it or connect to it in the MODE0.

Following commands are basic AT command available for configuration and operation settings.

Once above settings are done, the settings remain effect unless factory default reset is performed.

If you want to control the Bluetooth operation mode temporarily, you can use following commands.

For detail information of AT commands, please refer to “Appendix B: AT Commands” of the ESD user manual. http://www.sena.com/download/manual/manual_parani_esdv2-v2.0.2.pdf

1. Wi-Fi

Wi-Fi is a trademark of the Wi-Fi Alliance that may be used with certified products that belong to a class of wireless local area network (WLAN) devices based on the IEEE 802.11 standards.

Wi-Fi allows local area networks (LANs) to be deployed without wires for client devices, typically reducing the costs of network deployment and expansion. Spaces where cables cannot be run, such as outdoor areas and historical buildings, can host wireless LANs.

Wireless network adapters are now built into most laptops. The price of chipsets for Wi-Fi continues to drop, making it an economical networking option included in even more devices. Wi-Fi has become widespread in corporate infrastructures.

Different competitive brands of access points and client network interfaces are inter-operable at a basic level of service. Products designated as “Wi-Fi Certified” by the Wi-Fi Alliance are backwards compatible. Wi-Fi is a global set of standards. Unlike mobile phones, any standard Wi-Fi device will work anywhere in the world.

A typical wireless router using 802.11b or 802.11g with a stock antenna might have a range of 32 m (120 ft) indoors and 95 m (300 ft) outdoors. Due to reach requirements for wireless LAN applications, power consumption is fairly high compared to some other standards.

Because of the very limited practical range of Wi-Fi, mobile use is essentially confined to such applications as inventory taking machines in warehouses or retail spaces, barcode reading devices at check-out stands or receiving / shipping stations.

2. Bluetooth

Bluetooth is a standard and a communications protocol primarily designed for low power consumption, with a short range (power-class-dependent: 100m, 10m and 1m, but ranges vary in practice) based on low-cost transceiver microchips in each device. Bluetooth makes it possible for these devices to communicate with each other when they are in range.

In most cases the effective range of class 2 devices is extended if they connect to a class 1 transceiver, compared to a pure class 2 network. This is accomplished by the higher sensitivity and transmission power of Class 1 devices.

Bluetooth uses a radio technology called frequency-hopping spread spectrum, which chops up the data being sent and transmits chunks of it on up to 79 frequencies. Bluetooth provides a way to connect and exchange information between devices such as mobile phones, telephones, laptops, personal computers, printers, Global Positioning System (GPS) receivers, digital cameras, and video game consoles through a secure, globally unlicensed Industrial, Scientific and Medical (ISM) 2.4 GHz short-range radio frequency bandwidth. The Bluetooth specifications are developed and licensed by the Bluetooth Special Interest Group (SIG). The Bluetooth SIG consists of companies in the areas of telecommunication, computing, networking, and consumer electronics.

Bluetooth exists in many products, such as telephones, modems and headsets. The technology is useful when transferring information between two or more devices that are near each other in low-bandwidth situations. Bluetooth is commonly used to transfer sound data with telephones (i.e., with a Bluetooth headset) or byte data with hand-held computers (transferring files).

3. ZigBee

ZigBee is a low-cost, low-power, wireless mesh networking proprietary standard. The low cost allows the technology to be widely deployed in wireless control and monitoring applications, the low power-usage allows longer life with smaller batteries, and the mesh networking provides high reliability and larger range.

ZigBee operates in the industrial, scientific and medical (ISM) radio bands; 868 MHz in Europe, 915 MHz in the USA and Australia, and 2.4 GHz in most jurisdictions worldwide. The technology is intended to be simpler and less expensive than other WPANs such as Bluetooth.

Because ZigBee can activate (go from sleep to active mode) in 15 msec or less, the latency can be very low and devices can be very responsive — particularly compared to Bluetooth wake-up delays, which are typically around three seconds. Because ZigBees can sleep most of the time, average power consumption can be very low, resulting in long battery life.

ZigBee protocols are intended for use in embedded applications requiring low data rates and low power consumption. ZigBee’s current focus is to define a general-purpose, inexpensive, self-organizing mesh network that can be used for industrial control, embedded sensing, medical data collection, smoke and intruder warning, building automation, home automation, etc. The resulting network will use very small amounts of power – individual devices must have a battery life of at least two years to pass ZigBee certification.

4. The key characteristics of Zigbee, Wi-Fi and Bluetooth

Depending on the desired applications, Bluetooth and Network mode of the MSP1000 should be configured appropriately

Bluetooth mode configuration based on the direction of the connection attempt

1. Bluetooth pairing mode

1.1 Connector

In this mode, the MSP1000 searches for peripheral Bluetooth devices at every scan interval specified and tries to connect them. Peripheral Bluetooth devices can be searched by IAC or Bluetooth name.

1.2 Acceptor

The MSP1000 accepts connection requests from other Bluetooth devices.

1.3 Custom

User can allow only specific Bluetooth devices to connect with the MSP1000.

Pairing mode can be assigned for each port.

- Acceptor: Allow a Bluetooth connection from a specific Bluetooth device

- Connector: Try to connect to a specific Bluetooth device

2. Choice of network service mode

If you select ‘Service Category’-> Network, you can add the desired network behavior in Network Service configuration.

- Server: Waiting for TCP connections from clients

- Client: Try to establish a TCP connection to a predefined remote host

- Tunneling: This mode is a mixed way of Server and Client mode. By default, it operates as Server mode, however if TCP connection is not established and data is received from SPP, MSP1000 tries to connect to the predefined remote host.

- Vertex: In Vertex mode, one TCP connection is shared for communication with multiple Bluetooth devices. This mode has similar behavior as RS422/485 multi-drop mode.

3. Modes of operation according to applications

Commonly used combination of Bluetooth and Network operation modes in real applications are as follows:

3.1 Custom -> Acceptor, Server type

Application Examples:

http://www.sena.com/newsletter/casestudy/200806_casestudy_eng.html

http://www.sena.com/newsletter/casestudy/200807_casestudy_eng.html

http://www.sena.com/newsletter/casestudy/200809_casestudy_eng.html

http://www.sena.com/newsletter/casestudy/200904_casestudy_eng.html

http://www.sena.com/newsletter/casestudy/200907_casestudy2_eng.html

http://www.sena.com/newsletter/casestudy/200912_casestudy_eng.html

This is the most widely used operation mode, and in most cases, Parani-SD or other Bluetooth devices attempt to connect to MSP1000.

SD tries to connect to MSP1000, so it loads lighter on the MSP1000.

For this configuration, set SD’s mode to Mode1, and SD always attempts to connect to MSP1000 whenever it is turned on.

Once Bluetooth connection is established, the MSP1000 listens to the TCP port for connection establishment. User can use Serial/IP or other TCP client program to connect to the MSP1000 over TCP/IP.

The MSP1000 uses Custom->Acceptor pairing mode, so only specified device can connect. And Specific port number can be assigned to each device connected to the MSP1000. This operation mode is mostly used when user knows which devices will connect.

This operation mode has following advantages:

- Specific Bluetooth devices communicate with MSP1000 using specified TCP ports, so PC software knows which devices are connected.

3.2 Acceptor, Client type

http://www.sena.com/newsletter/casestudy/200902_casestudy_eng.html

A Bluetooth device which wants to send data makes a request for connection. If Bluetooth connection is established, the MSP1000 connects to the specified remote host and send the received data.

This mode is useful when multiple Bluetooth devices communicate with a common server.

3.3. Connector/Client type

This combination is used when unknown multiple devices communicate with a server through the MSP1000.

http://www.sena.com/newsletter/casestudy/200812_casestudy_eng.html

http://www.sena.com/newsletter/casestudy/200905_casestudy_eng.html

The MSP1000 searches nearby Bluetooth devices. If the MSP1000 successfully finds the devices which meet the condition (IAC or name), the MSP1000 connects to the device. Once the Bluetooth connection is established, the MSP1000 attempts to connect to the specified host over TCP/IP.

This mode is suitable for Proximity Marketing solution or similar applications which needs to communicate with a lot of Bluetooth devices but the data length is relatively short.

4. Summary

Generally, the Bluetooth operation mode of Acceptor/Connector is determined by the behavior of Bluetooth devices to communicate with the MSP1000 – whether to request Bluetooth connection to the MSP1000 or to allow Bluetooth connection from the MSP1000.

The Network operation mode (Server/Client) depends on how user software works – TCP Server or TCP Client.

Depending on applications, user can set proper operation mode to get desired behavior.

3.2 Data direction: Slaves to Master

M: Master

S1, S2, S3, S4: Slave1, Slave2, Slave3, Slave4

4. Conclusions

In low baud rate, there is a slight difference in performance, if any, between the multi-drop mode of the MSP1000 and the SD1000. However  in high speed baud rate, the multi-drop mode implemented by the MSP1000 shows much better performance mainly due to the difference of hardware performance.

The MSP1000 also supports more slave connections than the SD1000. (MSP1000: up to 27 slave connections, SD1000: up to 4 slave connections) As the connections of slaves increase, the performance can be lower, in some cases.
