Hello everybody.
I'm an engineering student and for my final thesis I will work with the beaglebone black.
The project is aimed to allow two beaglebone black to communicate wirelessly in real-time.
The data that has to be transmitted will come from an ethernet cable, using Powerlink (http://www.ethernet-powerlink.org). So from one side there will be the ethernet cable connected to the sensor, the beaglebone and the wifi module, from the other side another bbb +wifi connected via ethernet to a computing unit.
The goal is to create a diagnosis infrastructure for not easily accessible parts via cables in industrial environment (e.g. Rotating parts).
Since I'm totally new to the beaglebone, I would like to ask you if this is a feasible project, if there are wireless modules that allow this kind of behavior or if there is some documentation talking about the topic.
Any type of help or suggestion is very welcome, if something is not clear I can provide more details. Thank you!

I guess "real-time" is not possible over wlan. Depending on how
critical time is. ns for sure is not possible;(

However, it's easy to misuse any linux computer as a wireless
accesspoint. see e.g.
https://seravo.fi/2014/create-wireless-access-point-hostapd. And the
other bbbw will bravely connect, if configured correctly...

It is for diagnosis purposes, so I don’t know how long should be the cycle. I know that with wlan is not possible to have a cycle time shorter than 15-20ms, but this should be ok.
