Recommend BCM. There are many third-party drivers.
Bcm and csr are the names of Bluetooth chip manufacturers. The main chips of Bluetooth adapters are CSR, Broadcom, Taiwan Province Chuangjie and MSI.
When you say bcm, you mean Broadcom Broad.
This is the brand of Bluetooth chip, there is not much difference, but Nokia has always used it as CSR, so it seems that there are many users, but there are many software supporting BCM, and many Bluetooth schemes have used it in recent years.
EDR is a protocol, which is a supplement to Bluetooth 2.0 protocol. Bluetooth 2.0+EDR will be written to devices that support this protocol, regardless of BCM or CSR. With this protocol, the biggest advantage is that it can increase the bandwidth of Bluetooth. The direct use is to transfer files quickly, support stereo Bluetooth function, and connect more than two devices (for Bluetooth headset).
EDR(Enhanced data rate) is the abbreviation of enhanced data rate in Bluetooth technology, which is characterized by greatly improving the data transmission rate of Bluetooth technology, reaching 2. 1Mbps, which is three times that of current Bluetooth technology. Therefore, in addition to a more stable audio stream and lower power consumption, we can also make full use of the bandwidth advantage and connect multiple Bluetooth devices at the same time.
Question 2: What brand of Bluetooth chip is better? CSR should be the largest supplier of Bluetooth chips at present. Too many Bluetooth products are CSR solutions.
And Broad, Conexant, etc. Do some, too, but don't spell Bluetooth with CSR.
Question 3: Which chip should Bluetooth 4.0 ble choose to recommend TI? There are many agents who call themselves TI in the market. In fact, there are only two, namely, General Assembly and Xinye. The others are small dealers.
Question 4: What are the good recommendations for Bluetooth chips? Bluetooth chips are mostly used by Norway, the world's top semiconductor manufacturer, such as the classic Bluetooth chips nrf5 1822 and nrf52832, and the Bluetooth modules SKB360, SKB360I, SKB3 1, SKB362 and SKB365 of SKYLAB. Other small brands of Bluetooth chips can also be used, but the performance is not so reliable and the link is not so stable, so choose the chip. Just like why Plantronic Bluetooth headsets are so expensive, you will know when you have used them!
Question 5: Is the design of Bluetooth chip simple or complicated? The design of Bluetooth chip is not easy. It is a great challenge to integrate high frequency/radio frequency Bluetooth module with ARM kernel and low speed io. Moreover, for companies that provide Bluetooth chips, they also need to provide supporting Bluetooth protocol stacks, demonstration boards, even module boards, Bluetooth dongles and so on.
If you are interested, you can find related chip products. The main companies producing Bluetooth chips in the market are Kinetis KW4x and KW3x from NXP, CC25xx and 26xx from TI, nRF5 1xxx from Norway, etc. These companies can provide complete chips, SDK, demo, protocol stack, development board and technical support, which is difficult for other companies.
Question 6: Which of the three Bluetooth headset chips, csrbcm and edr, has better CSR: stable signal, low power consumption, distance of 7 7- 10/0m, high price, strong compatibility and multiple functions.
BCM: Stable signal, moderate power consumption, long distance, moderate price, strong compatibility and few functions.
EDR: Unstable signal, high power consumption, long distance, low price, sound flow and few functions.
Comprehensive evaluation, it is recommended to choose CSR, high-end brands, and low-frequency brands with low EDR cost performance can be used. BCM is a bit like chicken ribs.
Question 7: Which is better, Broadcom Bluetooth chip or csr? BCM, there are more third-party drivers.
Bcm and csr are the names of Bluetooth chip manufacturers. The main chips of Bluetooth adapters are CSR, Broadcom, Taiwan Province Chuangjie and MSI.
Bcm is Broadcom Broad.
This is the brand of Bluetooth chip, there is not much difference, but CSR has been using it, so it seems that there are many users, but BCM has a lot of supporting software, and many Bluetooth solutions have been used in recent years.
EDR is a protocol, which is a supplement to Bluetooth 2.0 protocol. Bluetooth 2.0+EDR will be written to devices that support this protocol, regardless of BCM or CSR.
With this protocol, the biggest advantage is that it can increase the bandwidth of Bluetooth. The direct use is to transfer files quickly, support stereo Bluetooth function, and connect more than two devices (for Bluetooth headset).
EDR is the abbreviation of Enhanceddatarate in Bluetooth technology, which is characterized by greatly improving the data transmission rate of Bluetooth technology, reaching 2. 1Mbps, which is three times that of current Bluetooth technology.
Therefore, in addition to a more stable audio stream and lower power consumption, we can also make full use of the bandwidth advantage and connect multiple Bluetooth devices at the same time.
Question 8: What CSR do Bluetooth chip suppliers have (UK)?
Advantages: The top Bluetooth module, playback and microphone sound quality on the market are the best at present. Compatible with all Bluetooth devices, ARM core and DSP core, with both ARM architecture and DSP architecture.
Disadvantages: it is expensive and does not support functions such as radio and card insertion.
Dezhou instrument company
Advantages and disadvantages are basically as above. The performance is excellent, but the price is more expensive.
Broadcom (Shanghai)
Advantages: the price advantage is obvious, and it also supports functions such as card insertion and radio reception.
Disadvantages: the sound quality is average.
Chuangjie (Taiwan Province Province)
Advantages: Good sound quality and voice prompt.
Disadvantages: the microphone effect is not ideal, and the compatibility is average.
There are also original factories such as Nordic and dialog.
At present, the performance of Bluetooth chip is at a certain level, which mainly depends on different chip types. For example, the Bluetooth scheme of Shanghai Broadcom is very mature, with a large number of shipments of keyboards and mice, anti-lost devices, bracelets, audio Bluetooth and digital Bluetooth' BLE Bluetooth'. Nearly half of the hottest sticks in 20 14 are made of Broadcom chips.
I am interested in Broadcom chips, and others who want to consult can talk privately.
Question 9: Does Bluetooth choose to buy a module or a chip? Of course, the chip is better.
