I had to download the FW(cc2640r2lp_host_test.hex) to CC2640R2 LaunchPad(with BOOSTXL-AOA) from SimpleLink™ CC2640R2 SDK 3.30.00.20
(\ti\simplelink_cc2640r2_sdk_3_30_00_20\examples\rtos\CC2640R2_LAUNCHXL\ble5stack\hexfiles),
And tried to execute the some HCI command via COM Port, Then Check the HCI Event, It Look like abnormally.
The CTE (Constant Tone Extension) feature can be used on the DTM (Direct Test Mode) with the CC2640R2 SDK latest version now?
