In sysconfig file of CC2651R3 in SDK 5.30, the TX-power can be set to 7dbm. Is it really?

Hi,
I recommend setting a TX power which falls in range of the datasheet.
For CC2651R3, the highest TX power is 5 dBm (datasheet).
Perhaps this resource could be helpful: https://dev.ti.com/tirex/content/simplelink_cc13xx_cc26xx_sdk_5_30_00_56/docs/ble5stack/ble_user_guide/html/cc13xx_cc26xx/software-on-cc13x1x-26x1x.html#choosing-launchpad-for-development
Thanks,

Hi Aries,
I see what you are referring to and noticed the additional PA table entries in the pasettings.json file of the SysConfig metadata for the CC2651R3 device. I will follow-up with Software R&D to further determine the reason for this and I expect it will be soon corrected.
Regards,
Ryan
It shouldn't make a difference. The maximum output power is +5 dBm.

Ryan
This is the code of CC2651R3's "ti_radio_config.c" which is generated by sysconfig 1.10 based on SDK5.30
