Hi
I want to run a chess tournament that uses Android tablets as the input for each player. These tablets will be placed on a table, where at the end of the table there will be a pc running Ubuntu. The tablets will communicate with eachother using Bluetooth. The tablets will also send the moves wirelessly to the pc running Ubuntu.
I want to know what the limitations will be on the pc in terms of receiving incoming data ? Thanks
It's probably going to depend on the number of connections your hardware supports.

lealsz Read size of LE Accept List
On my machine
$ sudo hcitool lealsz
Accept list size: 25Bluetooth is generally low bandwidth, so if you're just sending moves as short ascii strings, the machine isn't likely to be troubled.
Hi
Thanks for the info.
I will do a search to clarify what the distance limitation is for using Bluetooth. I assumed that the Wifi module in the Android tablet would be a better option to communicate with the pc ?
I'd forget BlueTooth (BT) for this and head for a classic WiFi Adhoc setup.
For my system which displayed a building door status in real time the demo system had a server which had an adhoc Wi-Fi setup so the clients could connect and send in status.
Wi-Fi has range and supported many connections so that part of the problem was solved.
Moving on to the system, the clients would connect to the MySQL server and update records when status changed in their area.
Then on the status display which didn't have to be the server an app there would update when the MySQL data changed.
That system was built in the 2003 so I'm not sure if any code would be found but the design lives on in products by other companies.
Ubuntu is a solid choice for a chess tournament! It's stable, lightweight, and great for running chess engines smoothly. Curious to know how it's working for you!
