请问CC2640R2F中drivers例程里面rfPacketTx运行后，可以使用2540 Dongle进行抓包吗?

用支持rfPacketTx的板子进行抓包，比如CC13X0

For IEEE 802.15.4g (15.4 Stack), RF proprietary and EasyLink protocols:

• CC1312R LaunchPad (LAUNCHXL-CC1312R1 with chip revision E/2.1),
• CC1352R LaunchPad (LAUNCHXL-CC1352R1 with chip revision E/2.1),
• CC1352P LaunchPad (LAUNCHXL-CC1352P1, LAUNCHXL-CC1352P-2 or LAUNCHXL-CC1352P-4 with chip revision E/2.1),
• CC1310 LaunchPad (LAUNCHXL-CC1310 with chip revision 2.1 or later) and
• CC1350 LaunchPad (LAUNCHXL-CC1350 with chip revision 2.1 or later).

补充一下，easylink的抓包支持目前仅限于sub1G以下，2.4G频段不支持，具体请看：
