Bluetooth Security Settings (Bluetooth model)
Select [Bluetooth Setup], and then select [Security], and you can change the Bluetooth security settings.
• If you change the security settings, the link key (pairing information) will be deleted. If the printer
is already paired with a terminal, unpair them and then pair again.
• When the security level is set to "Low", pairing is always possible, which increases the possibility of
unauthorized use by a third party. Change the setting at your own discretion and responsibility
with full understanding of the risk.
• Bluetooth LE always enables searching regardless of the security setting.
• If you connect without pairing with Bluetooth LE, communication is not encrypted.
• To communicate via Bluetooth LE, use the development kit (Epson ePOS SDK for iOS) that supports
the dedicated profile.
You can change the settings with TM-P20II Utility and Epson TM Utility.
