1. OverviewBT12 dual-mode Bluetooth module

bluetooth Dual-mode chip AB1122, using standard SPP Profilerealize transparent data transmission of traditional Bluetooth, and through embedded data transparent transmissiondedicated Service implements GATT-based BLE data passthrough.BT12 dual-mode Bluetooth module supports serial port command mode, liver implementationinteraction between external MCU and module. Users can use serial port commands to modelgroup for parameter configuration and some control, such as modifying the Bluetooth nameaddress, control module enters pairing, shutdown, etc.II. Features:.Bluetooth protocol: Bluetooth Specification V4.0 BLE, there is no byte limit for sending and receiving, and it has a further advantage than traditional Bluetooththe distance communication 4operating frequency: 2.4ghx ISM band +modulation mode: (Gauss an Fr equency Shift bonding) 4sensitivity: S-84dBm at 0.1% BER-security features: Authentication and encryption'supported services: Central & Per iphonal UUID FFE0, FFE1, FFE2 FFE0 are service UUD, and FFE1 is read data ∞channel, FFE2 is the write data channel) +workconsumption: low power consumption mode: standby current 1 -3mA, mobile phone transmission 3mA, Android mobile phone transmission 8mAo 4normal operation mode: standby is 8mA, and transmission is 8mAo 4power supply: + 3.9vdc 50mAxappearance size: 22mm x 12mmx 2mm +bluetooth certification: ROHS REACH 4transmission Distance: 10 -12 m3. Yingpian field: sthis module is mainly used in the field of short-distance wireless data transmission. It can be conveniently connected with the Bluetooth device of PCit can communicate data with smart phones. Avoid cumbersome cable connections and can directly replace serial port lines.
