Ok, I'll look at that later as I have to do some stuff pretty soon.

Ah, so. I have received my Feather M0 with WINC1500, and spent the last couple days trying to figure out to make happen what I thought would be an easy thing to do.
Please note that I don't know much programming - I learned BASIC in school, and some FORTRAN 77 in university, and the only program I've ever written was a simple game on a ZX81 to guess a random number, and get a celebratory smiley changing from :-| to :-) when you guessed the number, and to :-(, when you entered a wrong number.

After finding out that two of my USB cords were shot ... I finally started playing with Arduino, following the tutorials here.

What did I want to do? Create an offline wireless net-work (without internet) - and connect to it with two devices at the same time: My iphone, and the OpenAPS rig - which is an Edison sitting on a radio chip. Access Point.

The good news is that I learned a bunch about Ardunio. It did not take long, and I had an Access Point set up. Some time later, it was even password protected. But for some reason, only one device would connect at the same time. Surely a code problem.
Almost there, right?

Well, no. after a lot more research, I found out why ... it's a hardware limitation of the WINC1500 chip. :(

This I find, well, lame. Is it really that hard for a dedicated WIFI module and a pretty powerful chip to handle multiple clients connecting to its ad-hoc WIFI network/AP?
I guess I can try a workaround - somehow connecting the iPhone as a keyboard, and using the AP to connect the rig to the Feather. But for now, aside from me loving the form factor of the chip set, I would say I have an unnecessary wifi-enabled Feather sitting around. :(

I think that you guys should point that out in the description of the chip, since you speak about the ability to use it at a soft access point. (Which is why I bought it)

Cheers.

8.3 Limitations
• The AP can only support a single associated station. Further connection attempts are rejected.
• The ATWINC15x0 supports WPA2 security feature starting from the firmware version 19.5.x.
• Concurrency (simultaneous STA and AP mode) is not supported. Prior to activating the AP mode, the host MCU application must disable the mode that is currently running.
