Bluetooth dual mode is aimed at Bluetooth in the field of data transmission applications. It combines SPP and BLE, supports Bluetooth BR / EDR and BLE protocol. In dual-mode devices, these two technologies use the same RF front-end and antenna. Typical dual-mode devices are smartphones, tablets, PCs, and Gateways.
These devices can receive data sent by BLE or Bluetooth BR / EDR devices, and these devices often have sufficient power capabilities. The power consumption of the communication between the dual-mode device and the BLE device is lower than that of the communication between the dual-mode device and the Bluetooth BR / EDR device. The dual-mode solution requires an external processor to implement the Bluetooth protocol stack.
Advantages of Bluetooth dual mode:
1.Compared to BLE Bluetooth, the compatibility of Bluetooth dual mode is better, especially for connecting mobile phones from devices, due to the diversity of Android system, compatibility with Android mobile phones is better;
2. Compared with classic Bluetooth, the dual-mode Bluetooth has better compatibility and transmission speed. It can support both IOS devices and classic Bluetooth Android devices, and it can also meet the speed requirements of devices;
3. Compared with audio Bluetooth, it can also support the transmission of BLE and SPP protocol data on the basis of meeting the protocols of audio, phone book, telephone, etc., which fully meets the requirements of audio + data.
For those devices that are widely used and need to adapt to various types of IOS and Android devices, or devices that require data, Bluetooth dual mode is the best choice.
In the application of Bluetooth dual-mode, Feasycom is the earliest and most professional researcher and manufacturer in China, based on various chips, such as CSR, TI, Realtek and other chips, and launched a series of Bluetooth dual-mode modules: BT909, BT836B, BT826, BT806, etc.
Among them, BT806 can support both dual-mode data and audio, phonebook and other protocols, and the dual-mode module technology is more compatible than other manufacturers in the industry.
The transmission speed is faster, and the dual-mode module for multi-connection applications was first happened in China, which can support 7 Android devices and 1 IOS device to connect at the same time.
In response to the problem that IOS Apple devices can only use the BLE protocol for data transmission and the amount of data is relatively small, the dual-mode module provided by Feasycom has joined Apple’s IAP2 protocol, which can support Apple MFI certification, which can better meet customer requirements.
