CWBT05
Ultra Low Power System-on-Chip
Bluetooth 4.2 Module
General Description
CWBT05 is a high performance, low power radio transmit and receive
system module use Realtek BLE 4.2 RTL8752CGF as the controller
chips. It has the smallest volume package in the industry, and size is
17*24.7mm, suitable for most applications which pay more attention to
the size. This module has integrated the complete standard low energy
Bluetooth 4.2 protocol. Customer's MCU could connect to the module
by UART port, and it will automatically send a broadcast code after the
module starts. As the master, APP device can scan and search the
broadcast from module in order to establish the connection. After
success, it can conduct two-way communication link with mobile device
APP by serial port. Through UART interface, the user can exchange
data or control the communication parameters of module. The meaning
of data is defined by the upper application user. The mobile device can
operate to the module through APP, and the data will receive by the
module and pushed through UART MCU. After the module received a
data packet from the client MCU serial port, it will be automatically
forwarded to the mobile device.
