Changing advertising Power

Mano Kutty

Hi,

I am using cc2541- Keyfobdemo to my project.

I need to save power during advertisement.

Here i am attached image which is carrying the information of current advertisement.

1. Red circle shows current advertising power.

2. Green line shows current voltage consuming by advertising (Here i need to reduce).

3. Again the other two circles shows 100 mV and 250 ms, Which means the ratio of current power taking.

My Requirements:

I need reduce the Power of Advertising- without changing advertising interval.

Tried methods:

{
int8 initialTxPowerLevel = 0;

ProxReporter_SetParameter( PP_TX_POWER_LEVEL, sizeof ( int8 ), &initialTxPowerLevel );
}

2. HCI_EXT_SetTxPowerCmd( HCI_EXT_TX_POWER_MINUS_0_DBM );

3. HCI_EXT_SetTxPowerCmd( HCI_EXT_TX_POWER_MINUS_6_DBM );

4. HCI_EXT_SetTxPowerCmd( HCI_EXT_TX_POWER_MINUS_26_DBM );

5. PP_DEFAULT_TX_POWER

6. And i am using 1285ms advertising interval for maximum and minimum.

After this modification transmit power got changed during connection.

But Still i am unable to change the transmit power of advertising.

I welcome you all yours suggestions to solve this problem.

Thanks with best wishes,

Mano MM.

Hi,

You can also choose to advertise on one or two channels only.

Thanks for your valuable reply.

Here i am using all channels-- GAP_ADVCHAN_ALL (GAP_ADVCHAN_37 | GAP_ADVCHAN_38 | GAP_ADVCHAN_39)

But if i am using single channels - GAP_ADVCHAN_37 or GAP_ADVCHAN_38 or GAP_ADVCHAN_39 i am able to modify the transmit power.

Actually, i need to reduce the transmit power in all channel modes.

In this situation what is the possibilities to reduce the advertisement transmit power?

Best wishes with thanks,

Mano MM
