TX power

Hi Dialog,

Could we reduce the radio tx power level through setting some registers or calling api functions?

I want to shorter the radio and save some battery power at the same time.

Thanks!

Hi,

SDK 3.0.8 has the following API available: rf_nfm_enable();

Thanks,

Hi TR_Dialog,

Thanks for the information. Where can I get SDK 3.0.8?

Thanks,

Hello

Sorry if it is a stupid question, but I wanted to know:

Does rf_nfm_enable() work only for connections or for advertising also ?

If it does not work for advertising, how do we control advertising power level ?

Hi ankitdaf,

When the BLE is in advertising mode its purpose is to be tracked by the all the near devices, advertising in near field has no particular purpose although i dont think that when operating in near field mode has something to do with the operation you perform. The near field mode works for advertising as well.

Good to hear that, thanks !

The experience I am thinking of benefits greatly if advertising is done for a much shorter distance, so this should help !

I find the possibility of reducing energy for Bluetooth Low Energy very very exciting , it could open up a lot of use cases.
Any chance capability to further reduce power levels will become available anytime soon ?

Hi ankitdaf,

By using the Near field mode isn't going to further lower your power consumption, if that is what you are expecting. Also i am not aware if there are any improvement on the new SDK about lowering the energy the consumption.

Thanks MT_dialog

I am actually expecting the

I am actually expecting the distance over which the advertisement becomes broadcast to go down, will that happen ? That's all I need !

Hi ankitaf,

In near field mode you are going to be able to broadcast in shorter ranges. You cant test it by enabling the near field mode and by using a simple BLE application check the RSSI between the normal and Near Field mode.

Thanks MT_dialog
