If you read the latest Proximity draft (not from bluetooth.org, from the mailing lists), you will see that the recommendation to read TX power once on LE is to conserve power (specially on the single mode device, I suppose, but it would waste power on the BlueZ side as well). Unfortunately, if they change the recommendation again (in this case they would be returning to a previous decision), we would inevitably have to change implementation anyway. > In addition, TX Power for BR/EDR may change during the > connection (by the controller, depending on LMP commands), so reading it > periodically and updating the GATT server must be implemented. I don't really feel comfortable on discussing things which are not adopted on BT-SIG yet but... Are you aware of any latest GATT profiles which support BR/EDR? Be sure to check the latest drafts from BT-SIG mailing lists. I'm not saying it will *never* happen, but I think we should make development decisions on what we know at the moment, not on what might be possibly added to a future (not yet existing) profile. Otherwise we risk doing unnecessary things for current profiles, like reading TX Power periodically when a GATT profile would recommend reading once.
