As a short-range wireless communication technology, Bluetooth has been widely used, such as smart homes, medical equipments, wireless monitoring, automotive electronics, and so on. As the Bluetooth technology is very mature and the price is not high, there are many different sizes and types of Bluetooth modules available on the market, so how to choose the Bluetooth module suitable for your products?
1. ChipThe chip determines the computing power of the
Bluetooth module, and a strong "core" can ensure the performance of the Bluetooth module. For high performance requirements, you can choose TI, Nordic, Dialog, etc. Feasycom supply BT dual mode, BLE, and BT audio modules that based on chipsets from TI, Nordic, Dialog, Realtek, Qualcomm, etc. and are available for proof of concept use and placing bulk order.
2. Power consumptionBLE module is known for its low power consumption, but it has a variety of working status: broadcast (100ms interval), continuous transmission (20ms interval), deep sleep (µA), standby state (µA); The consumption is different in each status. This needs engineers to confirm it according to the specific Bluetooth solution.
3. StabilityEspecially as a communication module in an industrial system, it pays special attention to stability and monitorability. The host system needs to know the working status of the Bluetooth module at any time. A good Bluetooth module should be able to provide external working status indication signals, link control signals and watchdog signal.
4. SizeNowadays, some portable smart devices such as smart watch, bracelets, electronic cigarettes, voice recorders, etc. pursue small size, so the size of the Bluetooth module should be small. Our minimum size BLE5.1 module FSC-BT690 is as small as 5.0mm*5.4mm*1.2mm, and it adopts Dialog DA14531 chip.

Transmission distanceBluetooth is mainly divided into two power levels, the class 1 standard communication distance is 100 meters, and the class 2 standard communication distance is 10 meters (Class1 has higher power than Class2, and the communication distance is longer, and the corresponding Class1 radiation is greater). Before determining which BLE module meet the data transmission requirements according to the distance in the actual application of the
Bluetooth solution, developers need to know what environment their products are used in and whether they need long-distance transmission. For wireless products that do not require long range, such as wireless mice, wireless headsets, and remote controls, you can choose a Bluetooth module with a transmission distance of more than 10 meters; for products that require long range, such as decorative RGB lights, you can choose a module of which the transmission distance is more than 50 meters.
6. CostPrice is the most concerned issue of many smart device manufacturers. Feasycom is the original manufacturer of Bluetooth modules and has obvious price advantages. we strictly control the quality of the modules and provides pre-sales and after-sales technical support. We have stocks of regular modules to ensure our customers can use low-cost, cost-effective Bluetooth modules.For product details, please kindly visit our website: www.feasycom.com , or contact our sales team directly.
