TI中文支持网问题1： 我现在正在使用CC2650芯片做蓝牙4.0开发，使用notify给手机发送数据最大速率约为4.7KB/s，请问这款芯片是否能实现高速通信？最高速度为多少？
问题2：是否蓝牙4.0实现低功耗，蓝牙2.0才是高速传输的优选？CC2650芯片是否支持蓝牙2.0？
以上是我的两个问题，请解答疑惑，万分感谢！

你的notify速度应该很好了。蓝牙语音可以考虑使用cc2564芯片，这个是传统蓝牙。cc2650属于ble 4.2低功耗蓝牙。

感谢答复！我这边传输的数据格式没有具体规定，但是希望做到实时传输，数据发送过来的速率是远大于目前蓝牙传输到手机的速度的，您给的意见我会参考一下，谢谢！

请问，cc2564芯片的实测的传输最大速率可以达到多少？优化的MCU的条件下测试。

There are two forms of Bluetooth wireless technology systems: Basic Rate
(BR) and Low Energy (LE). Both systems include device discovery, connection
establishment and connection mechanisms. The Basic Rate system includes
optional Enhanced Data Rate (EDR) Alternate Media Access Control (MAC)
and Physical (PHY) layer extensions. The Basic Rate system offers synchronous
and asynchronous connections with data rates of 721.2 kbps for Basic
Rate, 2.1 Mbps for Enhanced Data Rate and high speed operation up to 24
Mbps with the 802.11 AMP. The LE system includes features designed to
enable products that require lower current consumption, lower complexity and
lower cost than BR/EDR. The LE system is also designed for use cases and
applications with lower data rates and has lower duty cycles. Depending on the
use case or application, one system including any optional parts may be more
optimal than the other.

泪奔？这是CC2564 的资料吗？我读了CC2564最大的传输率才是4Mbps。

上面的是BLUETOOTH SPECIFICATION Version 4.0 。下面的是CC2564的4mbps受限于UART。
UART Interface With Support for Maximum Bluetooth Data Rates
UART Transport Layer (H4) With Maximum Rate of 4 Mbps
Three-Wire UART Transport Layer (H5) With Maximum Rate of 4 Mbps(CC2560B and CC2564B Only)

but the bound rate of usart was capped at 1MHz, how it can up to 4Mbps transimision rate?
