Table 1 iBeacon Packet Format
Changing the Bluetooth Low Energy Technology Advertising Packet
The TM-m30II-NT can acquire a configuration script from the printer.
You can also change settings by transmitting the configuration script to the printer.
The configuration script only supports UTF-8 encoding.
The iBeacon Format is defined in the configuration script by default for the TM-m30II-NT.
You can change this Packet Format to support Eddystone-UID or Eddystone-URL.
However, the TM-m30II-NT only supports single Advertising Data Packets.
You can change the settings using either of the following two methods.
• Changing settings using the Epson TM-m30II Utility for Windows (see the TM-m30II Utility User's Manual
for details)
• Changing settings using an HTTP Request
The method of changing settings via an HTTP Request is explained below.
Digest authentication
You need Digest authentication to communicate with the printer.
The default ID and Password are ID: epson, Pass: serial number and are the same as the administrator for
Network settings.
