Page 13: Interfaces
To allow the eUniStone to enter low power mode, the host sets pin P0.14 low. When eUniStone is ready, it will also allow the host to enter LPM by setting P0.0 low. Before entering LPM, the host shall set UART CTS of eUniStone high. -
Page 14: Figure 3. Host Initiates Low Power Mode Entry And Exit
PAN1322 The host can wake up eUniStone by setting UARTCTS of eUniStone low again and setting P0.14 high again, whereas the eUniStone can wake up the host by setting its own UART RTS low again and setting P0.0 high again. -
Page 15: Hardware Flow Control
1. The host allows eUniStone to enter low power mode 2. eUniStone starts to enter low power mode 3. When UARTRTS is high and P0.0 is low, eUniStone enters low power mode. The host may now enter low power mode by signaling UARTCTS high. -
Page 16: Gpio Interface
GPIO Interface Most digital pins on eUniStone can be used as general purpose I/O’s (GPIOs). The GPIO pins are grouped into two ports: P0 and P1. P0 has 16 pins (P0.0 - P0.15) and P1 has nine pins (P1.0 - P1.8). -
Page 17: Power Supply
“ROK” is sent via UART to the host. After receiving the startup response, the host is informed that the eUniStone module is ready to work. The range for the startup time is indicated for each application SW release in the Release Notes [3]. -
Page 18: Power Down Through Onoff Pin
PAN1322 RESET# SDA0 UARTRTS UARTTXD Figure 5. Example of EEPROM Access at Start-up Power down through ONOFF Pin If VSUPPLY, VDDUART and VDD1 are supplied by the same source, it is not possible to switch off the module with the ONOFF signal. When the ONOFF pin is driven low, the reference levels VDDUART and VDD1 must also be switched off. -
Page 19: Operation Modes
Commands to eUniStone shall be ended with carriage return and line feed. Responses from eUniStone will be ended in the same way. E.g. for SW reset, AT+JRES<cr><lf> sent to eUniStone will be responded with ROK<cr><lf>. (“<cr><lf>“ might be omitted in further descriptions of commands and responses) After a SPP connection is set up to another device, data is sent using the command AT+JSDA. -
Page 20: Switch From Command Mode To Stream Mode
If the remote device is off (e.g. powered off or out of range) when the eUniStone module is in stream mode, stream data cannot be transmitted any more on the air. Hardware flow control stops any further UART communication as soon as the module’s UART input buffer is full. -
Page 21: Accessory Development Compatible With Smart Phones
This application can run on a micro-controller, FPGA, PC or similar. When writing the host application, there are some things that need to be considered. A host solution with eUniStone that is communicating with mobile solutions on Android, iPhone and Windows phone 8 will need to take specific considerations for the host application depending on Smart Phone/OS. -
Page 22: Accessory
PAN1322 The host application that controls eUniStone need to fulfill the control as required by the Accessory functionality. To control the Bluetooth link using eUniStone minimal requirements must be covered since the entire Bluetooth stack is included in eUniStone. -

Page 24: Host Application
5.1.2 Host Application The focus of this part is to provide information on how to control, initialize and configure eUniStone to make the accessory working with major Smart Phones. To design the host application the commands and responses in the SPP-AT specification [2] communication over UART interface are key. Also HW aspects needs to be taken care of e.g. -
Page 25: Figure 8. General State Machine For A Host Application As Accessory
When being in the Not Connected or Connected state it is important to save power. The Not Connected state is most probably the normal state and LPM (Low Power Mode) should be used at all times as long as the host is not sending any commands to eUniStone nor receiving a wake-up from Application Note Revision 1.2, 2013-12-18... -
Page 26: Smart Phone Compatibility Requirements
In the Connected state LPM should be used jointly with having the link in Sniff mode. LPM can also be used when the link is not in Sniff, but there is no power saving benefit since eUniStone has to use the high precision clock in this state. -

The procedure will vary and depend on the UUID, CoD and Input, Output Capabilities set with the security command on eUniStone. See chapter for detail about Android, Windows Phone and iPhone in combination with settings on eUniStone. Smart Phone specifics The various Smart Phones like Android, Windows mobiles and iPhone use their own OS’s and software and hardware implementations from various vendors. -

(or other Apps) connecting to specific Android Apps. In either case it is important that the chosen UUID is registered in eUniStone and used in the Android application. It is recommended to use a CoD other than 0x000000, since some Smart Phones with specific Android versions, will require this. -
Page 34: Security Settings And Connecting/Bonding To Smart Phone Versus App In The Phone
App needs to support such a procedure. The security command (AT+JSEC) is used to set the security for eUniStone, variable/fixed PIN and the Input and Output Capabilities. The Input and Output Capabilities are set according to the capabilities of the accessory. Depending on which capabilities are set the bonding with Android Smart Phones or a specific App has minor differences. -
Page 35: Android Market And Developing Apps For Android Smart Phones
1, 0. The reason for that is that the App is requesting a “secure RFCOMM socket” with man-in-the- middle protection. To be able to use the input, output combinations 0, 0 and 1, 0 on eUniStone the App should request an “insecure RFCOMM socket”. -
Page 36: Bonding
PAN1322 The Class of Device, CoD, written to eUniStone should also for a Windows Phone accessory reflect the functionality and features of the accessory as described in previous chapters, to be compatible with all three Smart Phones the CoD used should be 0x240704. -
Page 37: Programming Language For Windows Phone
Apple devices, implement an additional protocol layer on top of RFCOMM called iAP (iPod Accessory Protocol). The eUniStone host, hereafter referred to as the accessory, must identify and authenticate itself towards the Apple device to gain access to iAP Application Note Revision 1.2, 2013-12-18... -

Page 47: Via Holes
PAN1322 Figure 18. Example of a four layer stack-up 7.2.1.1 Via Holes Before starting with routing, the layout engineer must know what kinds of via are available. The choice depends from budget considerations: micro via are the most expensive, through via are the cheapest, the others are in the middle. -
Page 48: Phase 2: Components Placement
1. Place the connectors in the most rational way considering power distribution and interfaces. 2. Place the eUniStone module with the antenna on the edge of the PCB. Place all the other components in order to minimize track length and –if possible- keeping separate high frequency and baseband sections. - Page 49 Ground plane must be a continuous plane as large as possible, avoid to just “bring” the ground where is needed. b. eUniStone has several pins that must be connected to ground. Ideal would be to connect each pin with the ground underneath through via directly on pin. In case this cannot be done a trade-off must be found.

Page 50: Antenna
PAN1322 Antenna The manufacturer of the antenna is Murata. The model number is LDA21K. The antenna having 50 ohm impedance has been matched on the module to have good efficiency, and enabling the full power of the Bluetooth chip. The matching also assures that the best receiver sensitivity is achieved. -
Page 51: Test And Development Tools
9.1.1 SPP Toolbox The SPP Toolbox is used to control eUniStone with AT commands, to setup links and as described in later chapter, to do RF tests. A detailed manual is delivered with the Toolbox.

Page 53: Preparation For Rf Tests In Non-Signaling Mode
Preparation for RF Tests in non-signaling mode To perform RF tests in non-signaling mode, i.e. without a BT tester, the eUniStone has to be configured through HCI commands, which can only be executed on the eUniStone HCI application. To use the HCI commands, the HCI application must be downloaded into the EEPROM of the eUniStone module. -
Page 54: Figure 22. Download Of Hci Application Via Uart
Connect the AARDVARK Programmer and follow the instructions in [4]. When the HCI application is downloaded into EEPROM, issue a HW reset to load the HCI application in eUniStone. Note: It is important to read out and note the OSC_Trim value before download of the HCI application. -
Page 55: Restoring From Hci To Spp (Without Using Aardvark)
PAN1322 After the RF tests are performed, the SPP-AT application must be downloaded into EEPROM again to enable the usage of eBMU SPP Toolbox. Since the SPP Toolbox cannot work with the HCI application, the SPP-AT application is normally downloaded via I2C interface. This requires a specific I2C programmer. -
