Bluetooth socket connection


I am using a personnal android application with a personnal Bluetooth socket connection with my iMZ320 printer.

It seems like this connection socket is loosing its connection because sometimes and without any reason the printer didn't print when I send the file by Bluetooth.

Sometimes I can print 30 labels without any problems, and sometimes after only 2 or 3 labels print, I am loosing the Bluetooth connection.

Do you know if a Zebra Bluetooth socket connection is available and if this will improve the Bluetooth connection?

Many thanks for your support.
