It allows to communicate with ISO15693 products such as STMicroelectronics tags (LRIxx family) and Dual Interface EEPROM (M24LRxx family).
It also allows read and write NDEF message by using NFC features of Android OS. The NDEF message is a data format defined by NFC forum specification and offers interoperability of the different NFC devices.
NfcV-reader works with ISO/IEC 15693 and Dual Interface EEPROM contactless tag (Nfc-V on NFC forum).
Some new features are available such as, transfer file (upload or download a file), binary read and write. Also, Password management, Lock sectors management and Energy Harvesting management for M24LR devices.
1) To Read, Record , Monitor and Analyze Patient/User SpO2 and Pulse Rate from ST Pulse Oximeter device through NFC interface. ST Pulse Oximeter is integrated with M24LRxxE (Dynamic NFC /RFID Tag) to record SpO2 and Pulse Rate with date time stamp in its memory.
2)NFC based android phone can be used to read M24LRxxE and then to show the following :-
a) Application can be used to read Spo2 and Pulse Rate readings from M24LRxxE using NFC interface.
b) It can be used to show a user friendly graphical representation of history of readings in form of plot ( SpO2 vs Date-Time and Pulse Rate vs Date Time).
c) Application can also upload the health data to Microsoft HealthVault website on one click.
d) Pulse Oximeter device can be configured using Application like Manufacturer ID , Device Name etc . can be modified using application.

STM8L151G6 (32kb) [ex: FROG and Draco demoboard]
STM32L151RBT6 (32kb max over 128kb available) [ex: Pangolin demoboard]
STM32F103RBT6 (32kb max over 128kb available) [ex: Pangolin demoboard]
- any microcontroller board with usart connected to any rs232-bluetooth module.
[discovery kits, eval boards, frog, draco, pangolin boards]
- SPP Bluetooth HW module configured with "FROGxxxxx" name, and 115200,8,E,1 speed (the module should NOT be tied to the MCU reset signal)
Use the generic AT commands when the module is not paired to configure the speed, bit parity and name of the bluetooth module. It is suggested to use the MCU unique serial number so that multiple boards can coexist in the same area.
It is recommended for battery operated system that the MCU controls the bluetooth module power.
The flash S19 file is usually generated by the linker (project option, output Motorola format).
Copy this file to the phone internal's download directory.
With this tool a demoboard can be reflashed by email wirelessly and without PC/Laptops in minutes.
Bootloader does not use any of the 32kb user flash space, contrary to IAP (In Application Programming).
Even if the flashing is corrupted/interrupted, bootloader is always accessible.
We also suggest Teraterm-like application for user terminal operations.
Bonus Feature for developers:
Plot and Datalog values in user mode with this app:
In user mode, send by USART text ASCII strings with the following formatting style example:
(# sec):, 120, 201, LPS (PRaw_mb PQuad PFilt_mb C):, 1556.35, 1556.35, 1556.35, 27.49, ADS (Gain ADC12b Averaged):, 4, -3651, 4248
The text line should end with the return code 0x0A (next text line) separator
LPS is the main label, values in () are the physical units for the following data values
Send these information by Bluetooth from the MCU user code regularly (eg. 1 sec).
Click on the [START] button, and when the graph legend disappear, click on [Sel Plot], which will show a list of the decoded values and names. Up to 8 curves can be plotted on the screen which looks like an oscilloscope's.
You will also be able to add some of the phone sensors to it.
All the Bluetooth incoming string data once the [START] button is clicked will be datalogged as FROGxxxx.txt in the phone download folder.
ZAirMeter is an app developed for users to quickly measure relative altitude.
Most barometers are sensitive enough to accurately record height changes of +- 0.4m and below.
1. Hold the device and click the button to take the first measurement.
2. Move to a different altitude (take elevator, stairway), then hold the device steady and tap again to take the second measurement.
3. The height (altitude difference) will be displayed.
Note: A longer acquisition time may provide more accurate measurement:
This can be done by pressing and holding the button for a longer time (over 4 seconds).
How does this work?
Higher altitude makes the air pressure decrease.
The app measures relative altitude (pressure differences) with measurements done within minutes using a generic pressure to altitude conversion formula.
Why measurements must be done within minutes?
Because the air pressure changes with weather, so measurements done in minutes are less affected from changing weather. Remember that 1mb variation corresponds to around 8.3m.
Why not showing the sea level altitude and the difference?
Because the sea level pressure altitude changes with the weather: to make a plane safely land, the local and present equivalent airport sea level pressure must be beamed to the landing plane. For the phone app, it would require using internet (roaming) access to airport's METAR data. For more reading on the subject, search on QNH altitude. (ever thought about the tides effect on the sea level pressure?)
Quiz: Would a phone placed within an inflated bladder bag be able to measure the weight of an object?
