Bluetooth/BT module BT12 dual-mode serial port BLE4.0
Productinformatie:
BT12 dual mode bluetooth module adopts dual mode chip AB1122 and standard SPP Profile to realize data transmission of traditional bluetooth. And through the embedded data transmission dedicated Service to achieve transmission of BLE data based on GATT. BT12 dual mode bluetooth module supports serial command mode, which is used to realize the interaction between external MCU and module. The user can configure and control the module through the serial command, such as modifying the Bluetooth name, address, the control module into pairing, shutting down, etc.
