WiFi Tablet makes Phone activate Hotspot Is there anyway to make a phone with android 4.3 automatically activate it's wifi hot spot at the request of a nearby android tablet.

For example, the tablet can message the phone via blue tooth to activate the phones WiFi Hotspot. 

This is so that the user doesn't need to take the phone out of the pocket to activate the Hotspot before using the Internet on the tablet, for example.
Sure. Multiple options, all involving tasker:


Requires two things: AutoRemote and tasker. With that combination running on your phone, your tablet can request to enable the hotspot via... uh, internet. So this won't work if your tablet has no mobile data.
So let's substitute AutoRemote: if your phone has NFC support, you could stick a NFC tag to your tablet, and use apps like Trigger, NFC ReTAG, again in conjunction with Tasker, to trigger the hotspot. Of course this would require NFC to be turned on.
If BT is turned on on both devices, they are paired, and set to automatically connect: Tasker has a "state condition" registering when a BT connection is made (Bluetooth Connected). You can specify the device as parameter. So as soon as the two are "close enough", this could turn the Hotspot on. As this only recognizes when the connection is made, to "reverse" (i.e. turn the hotspot off), you'd rather use the WiFi Connected trigger (reversed, i.e. when your tablet is no longer connected).
