CC1352P: Changing Tx Power from 20dBm do 14dBm or less in runtime using TI-15.4 stack (915MHz)

Part Number: CC1352P
Other Parts Discussed in Thread: CC1352R, SYSCONFIG

Hi there,

My project currently has a CC1352R using TI-15.4 stack at 915MHz (PHY 132) and Non Beacon mode.

We would be interested in migrating to CC1352P1 if it was possible to dynamically change the Tx Power from 20dBm (using high PA) to 14dBm or less (using normal PA), due to our power constraints. Is it possible?

Thanks for helping,
Bruno

Hi Bruno,

I don't think it's possible to change Tx power at runtime.

Cheers,

Thanks for you answer, Marie

1 - If we keep using the same PA (e.g. use only the normal PA), it is indeed possible to change Tx power at runtime, right? For instance between 0dBm and 14dBm.

2 - What would be the possible solutions for changing Tx power between 20dBm and 14dBm or less, if not in runtime? Do we need to do a full firmware update for this?

Thanks again for helping, our team really appreciates it,

Bruno

Hi Bruno,

You might find this thread useful.

As mentioned in the thread, Tx power is normally configured with Sysconfig, but according to the poster of the thread, it seems to be possible to change the Tx power at runtime when using the TI 15.4 Stack.
