There are many types of ব্লুটুথ মডিউল in the market, and many times customer can not choose a suitable ব্লুটুথ মডিউল quickly, the following contents will guide you to choose a suitable module under specific conditions:
1. চিপসেট, chipset determines stability and function of product during use, some customers may look for the famous chipset module directly, for example CSR8675, nRF52832, OF CC2640, ইত্যাদি.
2. Usage (data only, audio only, data plus audio), for example, if you’re develop a ব্লুটুথ speaker, you must choose one module supports audio profiles, এফএসসি-বিটি 802(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, ইত্যাদি.
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, ইত্যাদি.

3. কাজের দূরত্ব, 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, যেমন. the FSC-BT909(CSR8811) super long-range module.
4. Power consumption, mobile intelligent device mostly requires low power consumption, at this time, ফ্যাসিককম FSC-BT616(TI CC2640R2F) lower energy module will be suitable for you.
5. Bluetooth dual mode or single mode, for example, if only use ব্লা, you won’t need a dual mode module, if you need using SPP+গ্যাট or audio profiles+SPP+গ্যাট, a dual mode module will be suitable for you.
6. ইন্টারফেস, ব্লুটুথ মডিউল’s interface include UART, এসপিআই, আই 2 সি, I2S/PCM, analog I/O, ইউএসবি, 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. মাত্রা, if you need a small size module, FSC-BT821(Realtek8761, দ্বৈত মোড, data only), এফএসসি-বিটি 630(nRF52832, BLE5.0, data only), এফএসসি-বিটি 802(CSR8670, BT5.0 dual mode, data plus audio) are small size.
