Hi, I work with a bluetooth printer in my app.
This app runs in some tablets, and each tablet has assigned an own printer. Primarily each printer is manually paired with its tablet, in Android-Bluetooth settings. At the first run, the app connects to printer with serial.GetPairedDevices.
Sometimes it happens that the pairing printer-tablet is lost: the serial.GetPairedDevices doesn't find any device, and if I check in Android-Bluetooth settings, the printer is no longer paired. Then if I try to pair it again, it works. This happens with different pairs of tablet/printer, about once a month.
Why? It depends on what?
