I've been working on a project which works just fine on bluetooth. It's an app on my phone which displays data from a nano every board with a HC06 bluetooth chip.
I'm concerned about latency - bluetooth is not the fastest way to transmit data.
I know that arduino has a nano iot chip which supports wifi; but my question is can anyone point to a good tutorial or info on how to set up a wifi connection between arduino and android phone, no other connections? Is it possible to create a network between just the two units, with no routers or actual internet connection involved?
So far everything I've seen is just how to connect the iot board to your home wifi, which is not what I want to do. This has to work in remote locations where the phone and the nano board are only a few feet away, but there are not other connections being made.
Or should I look at other radio communication systems? Recommendations? Thanks for any response.
What is the latency You experience?
See if your phone has an option to create a hotspot.

It has yet to be determined. However, the device must make many repetitive calculations and then the data is sent to the phone where the software will again make many repetitive calculations (thousands of averagings) to display correct data. One engineer looking at the issue suggested BT might create a latency problem and we should think about a faster data transmission system.
Post that Nano code to give us some idea about calculations. If there is a multisampling reading of a sensor for averaging there could be an explanation there.

Have a look at Random Nerd tutorials they have lots of useful Wifi info, certainly there is a solution using ESP32 where the ESP creates a local WiFi network. I would think the same can be created with the Nano.

Highly questionable. Averaging would reduce substantially, the throughput of the serial channel. It sounds to me, more like there is a latency problem from the calculations. A faster transmission system won't fix that.
