Bluetooth 4.0 BLE CC2540 CC2541 IBeacon

Product Description

Bluetooth 4.0 BLE CC2540 CC2541 IBeacon

main feature:
1. Use simple, without any experience in the Bluetooth protocol stack;
2. The user interface uses a universal serial design, full duplex two-way communication;
3. supports bridging mode (serial transparent transmission), or directly drive mode (no additional CPU);
The default connection interval 20ms, fast connection;
5. Support AT commands modify the baud rate, software reset module, get the MAC address, to modify the name of the module;
6. Support AT command adjusting Bluetooth connection interval, control different forwarding rate. (Dynamic power adjustment);
7. The serial data packet length, can be any 200byte less (including 200) length. (Large package automatic distribution);
8. High-speed transparent transmission forwarding rate of up to 4K / S, can be stable at 2.5K-2.8K;
9. Support mobile devices APP modify Bluetooth module name, power-down save;
10. Support mobile devices APP modify the baud rate, power-down save;
11. Support for mobile devices APP module for remote reset;
12. support mobile devices APP adjust Bluetooth connection interval, down are not saved. (Dynamic power adjustment);
13. Support quick test, without connecting any external parts testing wireless and serial communications;
14. including the debug port, including a full IO foreign expansion;
15. supports the connection status, broadcast status prompt foot / general IO flexible configuration;
16.6 bidirectional programmable IO, external interrupt trigger input detection, all low-power operation. (Trigger alarm, lighting
Control, remote control toys, and other input and output switching applications);
17.2 Single programmable timer / cycle inversion output port. (Intelligent appointment time applications);
18. The two ADC inputs (14 bit), enable / disable, freely configurable sampling period. (Humidity, temperature, luminosity, etc. should
use);
19. The four programmable PWM (120Hz) output. (Dimming, control and other applications);
20. RSSI continuous acquisition module side, read automatically notify APP, enable / disable, collection frequency set free. (Find
Anti-lost alarm was applied);
21. Support module battery indicator, power to read, it can automatically notify. (Device power alerts);
22. support the anti-hijack password settings, modify and restore, to prevent malicious third-party connection. May not be used. independent
Password Operation results notification, convenient APP programming;
23. A low-power standby mode, CC2540 chip sleep current official data 0.4uA, measured power module as follows:
* 1 Note: Official Test mode: In the power loop resistor strings 10R, the use of an oscilloscope waveform interception drop,
Integrating computing.
* 2 Note: multimeter test mode: with a multimeter uA or mA profile string view displays values between cells and modules.
Test voltage is 3.07V.
