I have integrated into my Android app, Nearby Connection, to interconnect information between 1 or several devices to another that serves as a server.
The connection and the exchange work perfectly, but when they have exchanged information for a few hours, it seems that the device that makes the server becomes 'invisible', because the rest of the devices are disconnected at the same time. The last time it lasted 30h connected and then disconnected.
Does the token provided by the devices to connect by Nearby have an expiration? Can the 'server' device become invisible after a certain time?
