Azure Sphere can't see iPhone Hot Spot

techyg

I was able to get through all the steps of the Azure Sphere setup, up until I need to connect to wifi to get the device updated. I am in a locked down corporate environment, and need to use a phone hot spot for development. I am on the latest version of iOS (12.4).

 

I have tried adding my hot spot SSID using the "azsphere device wifi add --ssid <yourSSID> --key <yourNetworkKey>"

 

Unfortunately, this does not seem to work, and it doesn't see my iOS hot spot. I checked by running "azsphere device wifi scan" and it does see many other ssid's (that I don't have access to) so I know the wifi is working. I also confirmed it added my ssid by using the azsphere device wifi list command. I do see the SSID from my PC, and am able to connect to it, so I know the hotspot is working.

 

Based on some google searching, I believe the iOS hotspot is using WPA 2 Personal.  According to the MSDN documentation section "Configure Networking" it says that you need WPA/WPA2. Can anyone confirm that Azure Sphere should be able to use this? Or is there any step I am missing?

    I decided to try a check-in completely off the iPhone hot spot today.  Laptop on the hot spot.  Azure Sphere on the hot spot.  Parked in a random shopping center parking lot.

    It worked BUT I did have to increase the wait time to about 10 seconds for the Sphere to reconnect to the hot spot. 

    To allow enough time for the check-in program to get my IP, I'm using a PAUSE line in the sk_check.bat file.  Totally another e14 member's brilliance.  Not my own.

         sk_check.bat

         .....

         azsphere device restart

         echo.

         PAUSE   <---  Add this to the .bat file and it will wait for you to hit any key so... you can wait as long as you want to complete the script.  Simple and effective for spotty internet.

     

    The pause could also solve the network configuration issue that you've seen.  If the Sphere is slow to get back on the network during restart, you get the "not configured" IP error - but you probably already figured that out.  This second part is really for anyone new to the thread.

    It seems in my limited time with Azure Sphere, the programming for the wireless is on one M4F(Maybe) running at 200 MHz and not the A7 running at 500 MHz. This could account for the slowness. To use DHCP, takes a few interactions to setup the IP address. I have not analysed this to a great degree, but feel confident that is what we are dealing with.

    Hope this helps.

    I have an iPhone XR running IOS 13.2.2 and for the LIFE of me, I cannot get my Sphere to connect to it's hotspot. I updated my SDK to 19.10 AND the device to 19.10. No Joy.

     

    Is there a special incantation you must pass over the sphere to get it to connect to an iPhone?

    Bwiless (Brian Willess) suggested that I remove the ' from my iPhone name - "Gerry's iPhone". As soon as I did that it associated and connected!!

     

    BTW, the new -t addition in 19.09 works great for connecting to my hidden SSID network!

      Special characters can be troublesome for many connecting devices depending on how they are programed. At work we had someone with @ sign that messed up a macro badly. without that it worked fine.

    It turns out the @ sign and a number is a special command even when it is a data string. This is a Visual Basic like language macro.
