AWR1642: mmWaveLink: how to re-configure Profile, Chirp and Frame setting

Hi Hitoshi,
Profile/chirp which are used currently running frame can't be updated (in HW).
But there are few option where you can update chirp/frame/profiles.
1. Use Advanced frame configuration 'rlSetAdvFrameConfig' API which has flexibility to used different profile and chirp group.
2. API rlSetDynChirpCfg provides an option to update chirp configuration while frame is ongoing. Please refer detail of this API in rl_sensor.c file.
3. You can update profile parameters as well using rlSetProfileConfig API (pfCalLutUpdate = 0x3) without updating LUT but during the update make sure that particular profile is not being used for currently running frame/chirp. Chnage parameter of other profile-ID which is not running currently.

Hi Hitoshi,
In case to update chirp & profile when frame is on going this is the sequence
rlSetPrfileConfig, rlSetChirpConfig, rlSetFrameConfig-> rlSensorStart -> rlSetPrfileConfig(pfCalLutUpdate = 0x3) , rlSetDynChirpCfg.

In this sequence you can update chirp and profile parameters when frame is on going.


Other flow when you change chirp/profile when frame is stopped
rlSetPrfileConfig, rlSetChirpConfig, rlSetFrameConfig-> rlSensorStart -- [wait for some time]--> rlSensorStop-> rlSetPrfileConfig(pfCalLutUpdate = 0x3 or 0x0) , rlSetChirpConfig then rlSensorStart.

b/w sensorStop wait depends on your requirement, if you want some frames to be elapsed (where no. of frames =0 in frameConfig) or wait till finite no. of frames are elapsed (set in frameConfig).
