1) CDC is better for bluk data transfer. 12Mbps is the USB physical layer max speed. There will have many factors limit the data rate such as RF and the PC software that work with the CC2531. Genrally, 115200 can be achevied. Does it meet your requirments?
2) rf_modem - rfu***_cc2531 contains all the ...

Jerry,你好 :)
谢谢你的解答。
1)我目前的项目需求大概要求数据的传输速率在650KBytes/s以上,一般的U口传输应该都能到这个速率级别的吧,如果只是115200bps的话可满足不了需求(是虚拟串口的原因吗?)。假如采用CDC功能通信,能做到650KBytes/s以上吗?

1) 650kbytes/s is 5.2Mbps
For CC2531 with IEEE 802.15.4 radio the bitrate is 250kbps which is far below your requirements.
