Bluetooth 5.0 CSR8675 APTX audio module in bluetooth headphone and bluetooth speaker

  FSC-BT806 is a Bluetooth 4.0 dual-mode module (Software complies with the Bluetooth Core v5.0 Specification). It provides a Bluetooth Low Energy fully compliant system for audio and data communication with Feasycom stack.

  FSC-BT806 integrates an ultra-low-power DSP and application processor with embedded flash memory, a high-performance stereo codec, a power management subsystem, I2S, LED drivers and ADC I/O in a SOC IC. The dual-core architecture with flash memory enables manufacturers to easily differentiate their products with new features without extending development cycles.

  By default, FSC-BT806 module is equipped with powerful and easy-to-use Feasycom firmware. It’s easy-to-use and completely encapsulated. Feasycom firmware enables users to access Bluetooth functionality with simple ASCII commands delivered to the module over serial interface - it's just like a Bluetooth modem.

Things You Need To Know For Bluetooth Modules:


1 What is Bluetooth 5.0:

Two times transmission speed compare with Bluetooth V4.2,Max Trans Speed can reach to 24Mbps.

Effective work distance can be 300m, 4 times of Bluetooth V4.2.


2 What is Bluetooth Dual Mode Module:

Bluetooth Dual Mode Module is a Single-Module Bluetooth Solution with Built-in Bluetooth Basic Rate (BR)/Enhanced Data Rate (EDR)/Low Energy (LE) Functions.


3 What are the Bluetooth Dual Mode Advantages:

There are two most frequently applied Bluetooth Profiles for the general data communication between Smart Device and Bluetooth Peripheral: BLE and SPP.


In iOS, SPP is Only Available after the Bluetooth Peripheral passed the MFi Certification, in view of the high cost and complex process of the MFi Certification, BLE is much good to use. In Android Camp, BLE is Only supported by Android 4.3 and later versions of the Android OS, this lead to the serious system fragmentation issues and make a lot of Android devices has the bad compatibility for the BLE, so SPP has a huge advantage for data communication in android.


In Summary, If one product need to support iOS and Android devices simultaneously, our Bluetooth dual mode modules are the best choice.

4 What is the transmission distance for Bluetooth Modules:

Class 2 : 10M                 Class 1:  100M
