Upload BLEFirmata (include in the Examples of Arduino IDE)to your Arduino UNO. iPhone 5, iPhone 4S, iPad mini, iPad with Retina display (4th gen), iPad (3rd gen) or iPod touch (5th gen)x1ġ.Arduino Bluetooth Low Energy (BLE) Shield x1.Moreover Nordic’s ACI requires two hand-shake signals, RDYN and REQN, two additional pins will be used (pins 8 & 9 in the current implementation). Our BLE Shield is designed to utilize the SPI pins on the ICSP Header, therefore it is compatible with all three Arduino models. For Leonardo, the SPI pins are not connected to any of the digital I/O pins as they are on the Uno and Mega, they are only available on the ICSP connector. On the Arduino Mega, they are 50 (MISO), 51 (MOSI), 52 (SCK), and 53 (SS). On Arduino Uno, the SPI bus uses pins 10 (SS), 11 (MOSI), 12 (MISO), and 13 (SCK). Since we have to enable SPI interface for ACI communication, some I/O pins will not be available for other usage. *Consequently, the traditional CSN signal used to initiate an SPI transaction is replaced by two active low hand-shake signals RDYN and REQN. However, nRF8001 does not behave as a pure SPI slave device nRF8001 can receive new data over-the- air at any time or be busy processing a connection event or new data.All ACI data exchanges use a standard SPI interface, with nRF8001 using a mode 0 slave interface to the application controller. The physical ACI interface on nRF8001 consists of five pins.The ACI enables an application controller to communicate with nRF8001.Please refer to Nordic’s nRF8001 Product Specification for more details.Proprietary simple serial interface - Application Controller Interface (ACI).Support Peripheral (Slave) role operation only - nRF8001 IC limitation.Requires iPhone 5, iPhone 4S, iPad mini, iPad with Retina display (4th gen), iPad (3rd gen) or iPod touch (5th gen).Simple serial interface (ACI) supporting a range of different external application microcontrollers.Fully integrated, low tolerance 32kHz RC oscillator eliminating the need for external 32kHz crystals.On-chip DC/DC regulator enabling up to 20% peak current reduction for 3V cells.Best-in-class power consumption enabling months to years of battery lifetime when running from standard CR2032 coin cells.Cost-optimized solution for Peripheral (Slave) role operation.Fully qualified Bluetooth® v4.0 low energy Connectivity IC with integrated Radio, Link Layer, and Host stack. Use your iDevice as an internet gateway for your Arduino,etc. You can control and receive status of Arduino pins with an iPhone easyly,pass all sensors data from your Arduino to an iOS App for processing, The shield supports connection between Arduino and iOS device including iPhone 5, iPhone 4S, iPad 3rd generation and iPod touch 5th generation. This shield is designed to work with Arduino boards, including Arduino Uno, Mega and Leonardo.
