请问CC2640采用notify传输的最大速率是多少？

cc2540据说国外测试可以达到每秒4k字节以上！                                                                          
提供德州仪器蓝牙和射频cc2540,cc2541,cc26系列，cc13系列脱机烧录工具。



 

我的是CC2640
现在我是每隔200毫秒发送一个440字节的数据，基本是一发送就死机

你好，
CC2640在使能BT4.2的协议栈下可以做到100kbps的速率。
Result

Using the parameters described above, we are able to achieve a throughput of around 38.6kB/s without data length extension

Using data length extension and the maximum controller data payload we see a throughput increase to 100kB/s.

Throughput calculations can be done by hand following this equation
THROUGHPUT_KBPS = (NUM_PACKETS_PER_CXN_EVT) * (NUM_BYTES_PER_PACKET - TOTAL_PACKET_OVERHEAD)/ (CONNECTION_INTERVAL) With standard controller features the throughput example will use the following vars
NUM_BYTES_PER_PACKET = 27 bytes TOTAL_PACKET_OVERHEAD = 7 bytes CONNECTION_INTERVAL = 200ms With DLE enabled the throughput example will use the following vars
NUM_BYTES_PER_PACKET = 251 bytes TOTAL_PACKET_OVERHEAD = 7 bytes CONNECTION_INTERVAL = 200ms As an example, from the above sniffer capture 85 packets of 244 data payload bytes are sent in one connection event (200 ms). This comes out to 103.7kB/s which is similar to what Ellisys is calculating.
测试代码如下所示：
