4.8 CC2540 Bluetooth Module Test Experiment
4.8.1 Introduction to Bluetooth Module
Ble - UNO bluetooth 4.0 protocol is based on the perfect combination Arduino UNO by emakefun to
create customer research and development of a revolutionary product, function and the pin is fully
compatible with traditional Arduino UNO motherboard, scope of work frequency of 2.4 GHZ, modulation
mode for the GFSK, maximum transmitted power of 0 db, the largest launch distance of 50 meters, USES
the import original TI CC2540 chip design, support user through AT commands to modify view device
name service UUID transmitted power matching password instructions, such as convenient and quick to use
flexibleHowever, the product is very small in size, which is suitable for many applications with severe
restrictions on the size. We provide Android and IOS mobile phone demo.You can quickly develop a
communication with mobile phone hardware equipment as now very popular wearable mobile phone
peripheral equipment, can use Ble - Nano this development platform, you can use a Ble - UNO is connected,
with bluetooth 4.0 wireless transmission between two bluetooth devices, master-slave machine Settings.
Even with PC bluetooth HID connections AT the same time, we provide developers with a great degree of
freedom and support, the user can not only by the AT command debugging Ble - UNO, you can also add on
Ble - UNO controller board sensor Arduino compatible extensionEmakefun's exclusive bluetooth host mode
automatically connects to the slave, and supports sending over 20 bytes, making it easier to use
