How to choose a right bluetooth module for your application?

- Mar 11, 2020-

There has many types of Bluetooth module in the market, and many times customer can not choose a suitable Bluetooth module quickly, the following contents will guide you to choose a suitable module under specific conditions:

 

1. Chipset, chipset determines stability and function of product during use, some customers may look for the famous chipset module directly, for example CSR8675, nRF52832, TI CC2640, etc.

 

2. Usage (data only, audio only, data plus audio), for example, if you’re develop a Bluetooth speaker, you must choose one module supports audio profiles, FSC-BT802(CSR8670) and FSC-BT1006A(QCC3007) may be suitable for you.

 

If it’s used for transfering data, you need to know which type application you prepare to develop, for example, the simple one-to-one data communication, or mesh application, or one-to-many data communication, etc.

 

If it’s used for transfering audio, you need to know if it’s used for the simple one-to-one audio transmit or receive, or Audio broadcast, or TWS, etc.

 

Feasycom company has the all solutions, if you’re looking for that module solution, just feel free message us.

 

3. Work distance, if only short distance, the normal module can fill your need, if you need to transfer data for 80m or longer, a class 1 module will be suitable for you, e.g. the FSC-BT909(CSR8811) super long range module.

 

4. Power consumption, mobile intelligent device mostly requires low power consumption, at this time, Feasycom FSC-BT616(TI CC2640R2F) lower energy module will be suitable for you.

 

5. Bluetooth dual mode or single mode, for example, if only use BLE, you won’t need a dual mode module, if you need using SPP+GATT or audio profiles+SPP+GATT, a dual mode module will be suitable for you.

 

6. Interface, Bluetooth module’s interface include UART, SPI, I2C, I2S/PCM, analog I/O, USB, MIC, SPK etc.

 

7. Data transmit speed, different module’s transmit speed is different, for example FSC-BT836B’s transmit speed is up to 82 kB/s (Speed in practice).

 

8. Work mode, whether the module is used as master or slave, transmit audio or receive audio, if it’s used as master, should that module need supports transfer data to several slave devices.

 

9. Dimension, if you need a small size module, FSC-BT821(Realtek8761, dual mode, data only), FSC-BT630(nRF52832,BLE5.0, data only), FSC-BT802(CSR8670, BT5.0 dual mode, data plus audio) are small size.
