CC2652R: set rssi offset in smartRF studio

Part Number: CC2652R
Other Parts Discussed in Thread: CC1310, CC2592, CC1352R

Hi, 

when I use CC1310, I will set the RSSI offset in the override editor, 

    // override_phy_rx_rssi_offset_neg2db.xml

    // Rx: Set RSSI offset to adjust reported RSSI by -2 dB

    (uint32_t)0x000288A3,

But, i don't find the override editor in CC26xx. neither in BLE nor IEEE mode. 

could you help? set the RSSI offset in SRF studio.

    Why do you need to adjust the RSSI offset?

    As you have noted it's not possible to do in the SmartRF Studio GUI, what you potentially could do is to find the correct .xml file here: C:\Program Files (x86)\Texas Instruments\SmartRF Tools\SmartRF Studio 7\config\xml and modify the RSSI offset in this.

    Hi Ter,

    customer adds CC2592. So the RSSI has big offset now. input -100, but get -93dBm in the log window.
    so they would like to tune this in srf studio and then merge it into real code defination.

    I tried to search it in the distination folder, ...config\xml\cc2652_ieee_15_4_pg10, but unfortunitely, I can't locate the right place. could you guide more? thanks.

    Two options:
    - Add the override to the end of C:\Program Files (x86)\Texas Instruments\SmartRF Tools\SmartRF Studio 7\config\xml\cc1352r_ieee_15_4_pg10\overrides\override_ieee_802_15_4.xml file

    Ensure that the code export looks ok.
    - You can place the override in a separate file. If you look at C:\Program Files (x86)\Texas Instruments\SmartRF Tools\SmartRF Studio 7\config\xml\cc1352r_ieee_15_4_pg10\cmd_settings\setting_ieee_802_15_4.xml you can add a new file after the

    <!-- Override blocks to be concatenated into an override list for use with this command -->
    <Block>override_ieee_802_15_4.xml</Block>

    line
