cc2541 bluetooth 4.0 module UART Transceiver Module with Transparent Serial Port

Product Description   RF-BM-S02A BLE module applies CC2540 from TI as core processor. The module runs at 2.4GHz ISM band, with GFSK (Gaussian Frequency Shift Keying) modulation scheme. It has 40 channels (channel space at 2MHz), among which there are 3 fixed radio channels and 37 data channels of adaptive automatic frequency hopping. Physical layers can be combined with classic Bluetooth RF to form a dual mode device. And 2 MHz’s channel space can prevent interference from adjacent channels better. Besides, it has a wide output power adjustment (-23 dBm ~ 0dBm) and a high gain receiving sensitivity of -93 dBm. The module is designed to quickly connect electronic products with smart mobile devices, and can be widely used in various electronic devices, such as instruments, logistics tracking, healthcare, smart home, sports metering, automotive electronics, toys, and etc. With Android 4.3 smart devices integrated  with BLE technology, it will be a trend that BLE will be the standard configuration of smart phones. And the market demand on smart phone peripherals will increase geometrically. With this module, users can
integrate their existing solutions or products in the shortest development cycle, to occupy the market in the fastest speed, and to empower their company’s growth with the strength of new technology.   Features:
1. Easy to use, no need of any experience of Bluetooth protocol stack application
2. UART design for user interface, full-duplex bi-directional communication, and supporting the
minimum baud rate of 4800 bps;
3. Supporting bridge mode (USART transparent transmission), and direct-drive mode (no additional
MCU needed);
4. Default connection interval of 20ms, which makes quick connection;
5. Supporting software reset module by AT command, and access to the MAC address;
6. Supporting the adjustment of Bluetooth connection interval by AT command, and the control of
different forwarding rates (dynamic power adjustment);
7. Supporting the adjustment of the transmission power by AT command, the change of
broadcasting interval, the customization of broadcasting data, the customization of equipment UDID,
the setting of data delay (preparation time of user MCU USART receiving), the change of the
USART baud rate, and the change of the module names (all settings can be saved after power-off);
8. The length of the UART packets can be any below or equal to the arbitrary length of 200 byte
(large packet automatic distribution);
9. High-speed transparent transmission forward rate maximum up to 4 K/S and the stable rate to be
at 2.5 K to 2.5 K (IO5, IO6);
10. Supporting the change of module name by APP in mobile devices, the change of UART baud
rate and product UDID, the customization of broadcasting contents and cycle (all settings can be
saved after power-off);
11. Supporting the remote reset of module by APP in mobile devices, and the setting of
transmission power;
12. Supporting the adjustment of Bluetooth connection interval by APP in mobile devices but the
setting cannot be saved after power-off (dynamic power adjustment)   Schematic Diagram of Working Mode:   Product Description               Application      Packaging & Shipping   Packaging size and Pins   Company Information   RF-Star was founded in the year of 2010.
