Как выбрать модуль Bluetooth для вашего проекта

There are many types of Модули Bluetooth on the market, and sometimes developers cannot quickly select the suitable Bluetooth module. The following article will tell you how to select the appropriate module under specific conditions:

1. Bluetooth Чип.

The chip determines the stability and function of the product. Some customers may directly look for famous brand chip modules, такой какCSR8675, NRF52832, CC2640, и т. д..

2. Приложение. (только данные, Только аудио, Данные плюс аудио)

Например, if you want to develop a Bluetooth speaker, you must choose a module that supports audio profiles, FSC-BT802 (CSR8670) и FSC-BT1006A (QCC3007) может подойдет вам.

For data transmission, you need to know what’s the application you plan to develop, например, regular one-to-one data communication or advanced one-to-many data communication.

If it’s the audio transmission, you need to know whether it is regular one-to-one audio transmitting or receiving, or whether it is advanced audio broadcasting or TWS. And you should also know whether you need analog output or digital output.

3. Диапазон передачи.

If regular transmission range of 10m is good enough, our normal module can meet your requirements. If you need transmission range of 80m or longer, the ultra-long-range moduleFSC-BT909 (CSR8811) will be very suitable.

4. Энергопотребление.

Most portable devices require low power consumption. You can choose the FSC-BT616 (Ti CC2640R2F) which is an ultra-low power consumption module.

5. Bluetooth dual-mode or single-mode.

If you only use BLE, you don’t need a dual-mode module. If you need to use SPP + GATT or audio profile + Спп + ГАТТ, the dual-mode module will suit for you. Recommended dual-mode modules: БТ909, BT802, Bt836b, BT826.

6. Bluetooth Module Interface.

The interface of the Bluetooth module includes UART, SPI, I2c, I2S/PCM, аналоговый ввод/вывод, USB, Микрофон, SPK, и т. д.. You could just pick the ones that’s suitable for your applications.

7. Data transmission speed.

The transmission speed of different modules are different, например, the transmission speed ofFSC-BT836B is up to 82 кб/с (actual speed) while most of other modules can not reach this high speed.

8. Working mode.

Whether the module is used as a master module or a slave module, whether it needs to transmit audio or receive audio. If it is used as a master device, does the module need to support data transmission to multiple slave devices? These factors should be taken into account.

9. Bluetooth Module Size.

If a small module is required, FSC-BT821 (Realtek8761, двойной режим, только данные, 15mm*12mm), FSC-BT630 (NRF52832, Ble5.0, только данные, 11.7mm*10mm), FSC-BT802 (CSR8670, BT5.0 Двойной режим, data + audio, 12mm*10mm) are recommended.
