BLUETOOTH LOW ENERGY TINYSHIELD (ST)
ASD2116-R
DESCRIPTION
Our new Bluetooth Low Energy (BLE) TinyShield combines both master and slave
modes into one module! This TinyShield allows you to connect your TinyDuino system to
any compatible iOS or Android device using Bluetooth Low Energy (also known as
Bluetooth Smart and Bluetooth 4.1). This technology is great for low power sensors and
accessories and works with most modern phones. This shield acts as a drop-in hardware
and software replacement for NRF8001 (Nordic) TinyShield projects. Unlike previous BLE
TinyShields, your Arduino sketch code can modify your module's connection parameters
directly.
This TinyShield is based around the BlueNRG-MS chipset by STMicroelectronics, which
comes in the SPBTLE-RF module. The TinyShield also includes power supply and level
shifters on the board, so you can run your TinyDuino from 3.0V – 5V.
Since the SPBTLE-RF module supports both master and slave modes, you can
communicate both with a Bluetooth LE device (i.e. a smartphone) and another BLE
TinyShield or other BLE module with slave mode. If you have one of our previous BLE
models, a BlueGiga or a Nordic, it can communicate with those as well.
Note: This product is for advanced users, and typically requires that the user
develops their own iOS or Android BLE app in order to use this.

Pins Used
SPI Interface used
o
2 - SPI_IRQ: This signal is the interrupt output from the SPBTLE-RF to the TinyDuino.
o
9 - BT_RESET: This signal is the reset signal to the SPBTLE-RF.
o
10 - SPI_CS: This signal is the SPI chip select for the SPBTLE-RF.
o
11 - MOSI: This signal is the serial SPI data out of the TinyDuino and into the radio
transceiver.
o
12 - MISO: This signal is the serial SPI data out of the radio transceiver and into the
TinyDuino.
o
13 - SPI_CLK: This signal is the serial SPI clock out of the TinyDuino and into the radio
transceiver.
