I want to disable the dynamic power saving during inter-chirp IDLE times.
I have done the following changes to the SDK demo code:
I have added a function for setting the chirp configuration internally from the function MmwDemo_initTask . There i set the chirp configuration and before sending sensorStart I call
rlRfDynamicPowerSave(RL_DEVICE_MAP_INTERNAL_BSS, 0)
The 0 should disable all power saving.
The rlRfDynamicPowerSave call returns a suceess.
The code works fine for starting up the IWR6843 and selfconfiguring itself and it works as expected, just like configuring it using the normal way (not automatically from inside the firmware).
But the code does not result in the Tx being always on, which is what I want, Instead it results in the Tx always being off, the signal at least is much weaker now once I added the call to
rlRfDynamicPowerSave
Here is the code :
MmwDemo_initTask(....)

Cycleprofiler_init();

Can you tell if I am missing something? Since my current code results in Tx always being off, have I missunderstood the documentation and should it be the opposite? Or is there a way to simply disable the whole power save feature?
