Bluetooth technology is also in constant progress, at present the mainstream market, revolve around the following version:
2.1+EDR: the main users of low-end, but compatibility is wonderful, is also a version of the bluetooth technology;
3.1: the basic already belongs to eliminated, because he cost is low, also not low power consumption, also is not fit;
4.0: this is the mainstream of the market, positioning in the high-end products, such as: CSR solutions, gen jie and so on;
4.1: this is also the mainstream of the market at present, positioning in the high-end products, such as TI, zhongxing, winding up to.

Each scheme comparison and analysis:
1、the CSR plan: this is the old scheme, the highest market share, is also the most popular and recognized by European and American market.Downside is that the price is high, and small company if you want to do it, usually the supplier is not willing to cooperate, because this kind of product function changes and custom is more troublesome.
2、Texas instruments (TI: TI the scheme do not much on the market, the current bluetooth speakers use the millet, also only do big customers, small customer service.
3、zhuhai actions plan: as the old domestic package, does give homemade face many, product performance and quality is good, shortcomings is scheme, more cattle, small customers with enough.No power can't find them to do.
4、zhongxing and collaterals to scheme: the two schemes can also, but flexibility is lacking.
5、build glory and jerry scheme: the two scheme is worth highly recommended, why do you say that, because the two chips is the pride of our domestic, because of their existence, CSR, such as TI cow force companies to cut down the price.
Other advantages of the two schemes is also very obvious, low cost, stable performance.But is the power consumption do not come down, but for bluetooth speakers such occasions, in fact, no big problem.As a developer, more love is such a scheme.
6、nk and broadcom solution: the two also have nothing to say, is cheap.But the actual contact, the chip itself a lot of software bugs, development is very painful.
7、the rule of thumb
Although the market is very big, demand is very big, but in the actual product, we tend to first ask where is the market positioning,silverwing warned you, because only you had been product market positioning, to choose the right solution.Can't you product positioning in the high-end, and exported to Europe and the United States, also choose the lower part of the solution.Could not have your positioning of low-end products are exported to southeast Asia, and chooses the plan of high-end, so it is very important, we communicate with the customer in the first point.
At the same time, also want to consider whether their product features differentiation, if any, will not be able to choose the sort of high-end solution, why?Because such as CSR, gen jie, TI, can the function of the development are few, if you want to be a flexible customize a lot of features, choose the type of solution is not suitable, may be others promised to do, but actually do tend to get stuck in some places, lead to project progress the serious lag.
So, there is demand of customer, please be sure to position their products, as well as well as planning for their product, to find the right, and have the sincerity cooperate with manufacturers, in order to guarantee the products can go through smoothly.
