Bluetooth uses low power, and hence I keep it enabled indefinitely for whenever I want to tether with my laptop.

Wi-Fi is much faster and thus I prefer it over Bluetooth, but I can't keep the access point enabled indefinitely as it drains my battery too quickly.

Is there some way for me to enable & disable the Wi-Fi access point via its permanent Bluetooth connection to my laptop so that I can get faster tethering without having to keep the Wi-Fi access point enabled (and without having to touch my phone to enable/disable it)?

  • I don't know about any way doing that via Bluetooth. But would an alternative using NFC be acceptable, too? You didn't name your device, so I cannot tell if it supports NFC. Another option I could name would be "location aware", i.e. enabling WiFi whenever you're in a certain location, and disabling it when you leave it. Or similarly acting whenever another Bluetooth device is in reach (or gets out of reach). – Izzy Oct 24 '14 at 14:46
  • @Izzy: I see. Nope NFC isn't an option -- my laptop doesn't have NFC! But if I could make the Wi-Fi turn on whenever another Bluetooth device is in or out of reach that could be very useful too! How would I do that? – Mehrdad Oct 24 '14 at 18:59

Performing actions whenever a certain Blutooth device is in reach and paired (and reverting them when it gets out of reach) can be done e.g. with (see the tasker tag-wiki for details on the app):

  • Condition: BT Connected (parameter: name or address of the device)
  • Task: WiFi (parameter: On)
  • Exit-Task: (optional; Tasker should revert automatically to the previous state when the condition is no longer met) WiFi (parameter: Off)

This would similarly work with NFC when using the NFC plugin. More features are also offered by other plugins. Also see my Collection of Tasker Ressources for tutorials and available plugins.

  • Works like a charm, thanks. All I need to do now is just double-click my Bluetooth device and the Wi-Fi access point automatically appears! (The correct task for this seems to be "Wi-Fi Tether", not "Wi-Fi".) – Mehrdad Oct 24 '14 at 20:31

    Ah – facepalm sure, that's where the laptop comes in. Sorry for the lapsus. You're correct, in this case it's not "WiFi" but "WiFi Tether" :) But you've got the idea, so it wasn't that bad ;) Guess you'll find a lot of other interesting things you can do with Tasker – enjoy! – Izzy Oct 24 '14 at 20:38
