Forum Post: RE: TX Power configuration

Tx for the info.

I have checked in the datasheet and I agree with CC2541 values

for information bellow the CC2540 values.

We can see that CC2540 has a +4DB configuration not available on the CC2541

I have checked the .h files to see how to set values for CC2541:

What is available in the hci.h file:

#define HCI_EXT_TX_POWER_MINUS_23_DBM LL_EXT_TX_POWER_MINUS_23_DBM
#define HCI_EXT_TX_POWER_MINUS_6_DBM LL_EXT_TX_POWER_MINUS_6_DBM
#define HCI_EXT_TX_POWER_0_DBM LL_EXT_TX_POWER_0_DBM
#define HCI_EXT_TX_POWER_4_DBM LL_EXT_TX_POWER_4_DBM

My question: How to set TXPOWER value to -10DB by exemple ?

Do I need to use HCI_EXT_SetTxPowerCmd method or another one ?

Tx for your help.
