I'm not sure if this is the right sub or not, so please forgive me if this is in the wrong place, but I need some help picking out the right board for my project. Moderators: If this is in the wrong place, please let me know and I will either take it down and relocate to the correct place or if you have the power to, please relocate it and let me know that you have. Thanks.
Now onto the topic: I cannot go into too many details right now as it's a brand new project that I haven't seen done anywhere else before. It will involve multiple separate pieces each having potentially hundreds of sensors and each piece must be able to communicate with the Master unit (hereby referred to as receiver) over WiFi or Bluetooth. I was looking at the Mega, but it doesn't seem to have a WiFi module, so what I'm looking at now, is more than likely having multiple boards per piece interacting with each other over a direct/wired connection in a sort of sub-master/slave setup to accommodate the large number of sensors with the sub-master sending the sensor info from each of the slaves to the receiver over WiFi.
So this leads to my question: is the master-slave per unit setup even possible? If so what boards would one recommend? I was thinking of using a few Megas for each unit slaved to a MKR WiFi 1010 or possibly the Uno WiFi Rev 2. Or would it be better to use just the Megas with a USB WiFi dongle attached to one of them as the per unit master?
I know I mentioned Bluetooth earlier, but after a little more consideration, I realized that it may not be the best choice. As a point-to-point network Bluetooth would be great, but it's bandwidth is rather small and I will need near-instantaneous response time from multiple units communicating with the receiver simultaneously, which is why I decided that it must be a WiFi connection.
Thanks in advanced!
