CC2340R5: CC2340R5 : LP_EM_CC2340 : Tx Power is not supporting

Hello Krishna,

Thanks for reaching out, I am sending this to the appropriate expert.

Kind Regards,

Rogelio

HI Krishna, 

First, your sdk is not the the latest one, you have a pre-release one, please download this one as a lot of bug were fix since your version:

SIMPLELINK-LOWPOWER-F3-SDK Software development kit (SDK) | TI.com

Concerning the TxPower, can you detail a bit more what's means "is not working"?

Did you try this command on Btool? Did you check the current?

regards,

Now that I have changed the sdk, and I'm trying to send HCI_EXT_SetTxPowerCmd(); function from app_main.c in Basic_BLE_project. The command is not taking .

SDK : simplelink_lowpower_f3_sdk_7_10_00_35

TX power is disabled for 2340?

I tried "HCI_EXT_SetTxPowerCmd(HCI_EXT_TX_POWER_0_DBM);"

Module is going in unknown state. No advetisement.

Hello Krishna,

The HCI commands isn't supported, as far as I see you can to try to call HCI_EXT_SetTxPowerDbmCmd(int8 txPower, uint8 fraction) directly from the application level. (The command isn't yet available in Btool). The parameters aren't defines now but real inputs.

hope this help you a little,

Regards,
