Description
The module provides a connection of the microcontroller (e.g. Arduino) with the device equipped with operating system of Android (4.3+) or iOS. Unlike classic BT, BLE has no legal restrictions, iOS apps can be freely designed and shared. Board is recognized in the system as a simulated UART interface, via which you can send the ASCII characters between the devices in both directions.
Currently, Adafruit does not have its own app for Android. Right now, you can use the programNordic Android nRF UART.

The product is compatible with Arduino The manufacturer providesinstructions for the connectionand sample codefor Arduino users. |
Connection
The module can be controlled using any microcontroller, including Arduino, via simple serial SPI interface (pins MISO, MOSI, CCS). It has holes forgoldpin connectors- 2.54 mm pitch (strap included in the package). Below is a description of the individual pins.
| Pin | Description |
|---|---|
| VIN | Supply voltage in the range from 3 V to 5 V. |
| GND | The ground of the system. |
| SCK | Clock line of the SPI bus. |
| MISO | The data line of the SPI bus - output. |
| MOSI | The data line of the SPI bus - input. |
| REQ | Analogue CS (chip select) of the SPI bus. |
| RDY | Interrupt that signals the readiness of data to be read. |
| ACT | The outputs that signal whether the module nRF8001 is busy. |
| RST | Reset. |
| 3vo | The output from the voltage regulator of 3.3 V. |
