Part Number: CC1312R
We are using CC1312R and boost mode (CCFG.c setting to give VDDR1.95V.)
But the application can on the fly tune down output power in the code to 0 or even down to -10dBm
However the setting(txPower) we get from SmartRF studio and that is documenter in datasheet and in simplelink is based on the use of VDDR = 1.8V
Do you have other smartRF studio setting for txPower valid for VDDR = 1.95V?
If not, how can we go about to find these values ourselves?
If you are using boost mode then you should set CCFG_FORCE_VDDR_HH to 0x01 in the CCFG file.
To change RF power please see the EasyLink_setRfPower(int8_t i8TxPowerDbm) API in the EasyLink example in the SDK.
The entries of the txPowerTable are in the file ti_easylink_config.c
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to FI:
correction to above:
The entries of the txPowerTable are in the file ti_radio_config.c
I am not sure where the file ti_radio_config.c exists.
But there are power tables in smartrf_settings_predefined in the examples with the simplelink_SDK.
However, I think you missed my point. The CCFG.c to 0x01 it a flash page and is programmed once.
If my solution need 14 dBm, then it has to be set to with CCFG_FORCE_VDDR_HH to 0x01
The challange is to then during runtime, adjust down the RF power. Because all the settings for 12 dBm, 10 dBm etc are based on CCFG_FORCE_VDDR_HH to 0x00.
And writing to the flash ccfg.c during runtime is not something I want to do.
no more wires
In reply to no_more_wires:
I see your point now. I am afraid in that case we don't yet have a power table characterized for CC1312.
I will bring up next time I visit.
