Setting TX power for multiple advertising sets

[Bilal]

Hi, is it possible to set the BLE TX power individually for different advertising sets when multiple advertising sets are being used?

I am currently using the "hci_pwr_ctrl" sample project to read and write the BLE TX power but I am not sure how I can (or if it is even possible to) change the TX power and have set to different levels for different advertising sets.

I have a beaconing set that I want to have at a different level and a connectable adv set that should be at a different level.

Any suggestions? 

Thanks

You cannot do that with HCI API as this API does not identify sets, but I am not 100% sure if you can do this GAP api (best guess is that it is not possible).
I will try to check this in the code next week just to confirm this.

Susheel Nuguru any updates if you were able to confirm if this is possible?

Unfortunately this is not supported. Probably you can switch between two advertising sets so that only one is active at a time, so that the TX power can be set to the advertising role and not constrained to sets.

Please add a function to set TxPower for each AdvertiseSet in the future.

My application sends iBeacon and advertising for connection in parallel, but I want to change only iBeacon's TxPower.
Also, in the future, we would like to send PeriodicAdvertising in parallel.

For this reason, being able to set TxPower per AdvertiseSet is very important.

Syuji,

Have you seen this Vendor specific HCI API?

This API does not allow to set different power for extended and periodic advertising. The periodic advertiser and extended advertiser use the same advertising handle but you can use it on two advertising sets like the one you have iBeacon which uses legacy advertising set and the periodic advertising that uses extended advertising set.

Can you see if that is useful in your case?
