Dear Champs,

I am asking this for our customer.

The user is migrating from CC1312R7 onto CC1311R3.

Simplelink SDK version 6.20.00.24
Sysconfig version 1.13.0_2553
Code Composer studio version 11.2

But it seems there is no 14 dbm in the GUI, would you please show us how to set 14 dbm?

Can CC1311R3 support 14 dbm?

Hi Wayne,

The 14dbm setting needs a Force VDDR setting to be selected in Device Configuration Module.

Can you try to select that option in Sysconfig and check if the 14dbm option shows up?

Regards,

Sid

Hi Harkdtrt,

There seems to be an issue with the older version of the SDK. The answer by Arthur in this thread is a fix for the issue.

But the recommended approach would be to use the latest SDK. https://www.ti.com/tool/download/SIMPLELINK-LOWPOWER-F2-SDK/7.40.00.77

This already has the fixed issue.

Sid

Hi Sid:

Thanks.

Now I use the lateset SDK 7.40.00.77. I can configure Tx power 14dBm

But it will cause a lot of compile erorr.

Wake_on_radio_Tx can reproduce this error.

Hi Hark,

If your intention is to have the project rfWakeOnRadioTx on CC1311R3.

Then it is easier to start with the LP_CC1311P3 project and then migrate the device to CC1311R3.

Hi hark,

No, the CC1311R3's 5x5 package is not compatible with CC1311P3.
