Bluetooth V2.1 + EDR
Bluetooth Class 2
Built-in PCB radio frequency antenna
Support UART interface
3.3V power supply
Status indication LED: P12
Used to indicate the status of the Bluetooth module, LED flashing mode and Bluetooth module status corresponding to the following table:
Mode LED Displays the module status
(800 ms-on, 800 ms-off) waiting for pairing
Long to establish a connection
Host interrupt indication: P05
Used to indicate whether the host is interrupted or not, the connection status is high, and other states are low.
LAYOUT Note
1, SPP-CA Bluetooth module serial port level to be 3.3V, if and 5V level system connection need to increase the level conversion chip.
2, the Bluetooth signal affected by the surrounding large, such as trees, metal, walls and other obstacles to the Bluetooth signal will have a certain absorption or shielding, it is recommended not to install in the metal shell.
3, because the metal will weaken the antenna function, it is recommended to the module Lay board, the module under the antenna and not shop and alignment, it is best to hollow out.
