Other Parts Discussed in Thread: CC2538, Z-STACK

Hi All;

How much is the CC2538 maximum output power in tx mode without using CC259x?

Is there any API to configure RF power registers?

thanks;

Farhad.

According to CC2538 data sheet, the output power of CC2538 can be up to 7 dbm. If you are using TI Z-Stack, you can use API macRadioSetTxPower to set TX power.

The default value is set in macRadioDefsTxPwrTables[] which is defined in mac_radio_defs.c

Using SampleLight as an example, you can change TX power in zclSampleLight_Init().
