This is a serial bluetooth module that is compatible with both iOS and Android. Use it to send and receive wireless serial data through bluetooth. The BT12 Module is similar to a HC06 + CC2541 modules in a single package. This module can be used to receive serial data from phones, computers, laptops and other bluetooth module.
This module is simple to use. It operates between an input voltage of 3V3 and 6V. The Tx and Rx lines operate at 3V3, please use proper level conversion to avoid damage to the module.
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.
