BLE micro Bluetooth 4.0 communication module
1. PRODUCT INTRODUCTION
1.1 INTRODUCTION:
BLE micro is the communication module which is based on Bluetooth 4.0 technology. It uses a
micro encapsulation design, compact size, and is very convenient to be integrated into your circuit
board. It supports point to point wireless transparent transmission between two Bluetooth module,
master-slave machine settings, wireless burning program, even establish a HID connection with PC.
There are one transparent serial port, 19 GPIOs which can be set as input or output interface,
three 12-bit ADC Digital-to-Analogue Conversion channels (P04, P06, P07). These hardware resources
are all available for wireless device, you can use a smart phone to execute read or write operation
directly.
Meanwhile, DFRobot provides developers with a great degree of freedom and support. Users can
debug through the AT command directly and upgrade BLE firmware through USB port easily. BLE micro
Bluetooth 4.0 communication module can be integrated into the Arduino controller circuit boards, so as
to implement Bluetooth wireless control and Bluetooth wireless programming.
In addition, BLE micro supports the last Apple Inc iBeacon positioning, which can be used for
advertising functions such as automatic push for complementary goods.
