I just wanted to let everyone know, I was able to tether my iPhone 6s to my Nexus 7 v1 using Bluetooth. This allowed me to get internet on my nexus 7 WiFi using Bluetooth from my iPhone. Step 1) On iPhone turn on an set up a Personal hotspot Step 2) On iPhone turn on Bluetooth, On tablet turn on Bluetooth. Make sure WiFi is disconnected on both so you know it worked. Step 3) connect tablet to iPhone via Bluetooth. Step 4) if it is an android device, make sure you click on options on Bluetooth an enable sharing internet access in Bluetooth connection. Step 5) test internet! iPhone will state that 1 connection is made on hotspot. This worked for me. I will post a YouTube video of this later so you can see a better longer explanation. I just wanted to get this out to anyone who needs it! its going to help me a lot. I tested this on iPad air 1 and Nexus 7.
