Thanks!

Hello Zheng,

Link_test application provides reference to use CW mode. Please refer that to first run at your end.

/* Set continue mode configuration */

retVal = rlSetContModeConfig(RL_DEVICE_MAP_INTERNAL_BSS, (rlContModeCfg_t*)&contModeCfg);

retVal = rlEnableContMode(RL_DEVICE_MAP_INTERNAL_BSS, (rlContModeEn_t*)&contModeEnable);

Make sure if you set TxOutPowerBackoff to zero to get max output power.

const rlContModeCfg_t contModeCfg =

{

.startFreqConst = 1435384036,

.txOutPowerBackoffCode = 0,

.txPhaseShifter = 0,

.digOutSampleRate = 10000,

.hpfCornerFreq1 = 0,

.hpfCornerFreq2 = 0,

.rxGain = 30,

.vcoSelect = 0x0,

.reserved0 = 0x0

};

You can access link test in: C:\ti\mmwave_mcuplus_sdk_04_06_01_02\mmwave_mcuplus_sdk_04_06_01_02\ti\control\mmwave\link_test\awr294x

If i just change dfeDataOutputMode to 1 in CLI config, that is mean continuous mode?

Hello Zheng,

Continuous mode is not supported in the SDK.
