Auto Reconnect Feature
The auto reconnect feature allows the printer to automatically restore a connection in the following situations if
the Bluetooth connection to the iOS device is lost.
• When the printer is turned on
• When the signal is dropped and then restored
The following shows the printer operations and connection methods when the auto reconnect feature is enabled
or disabled.
Auto Reconnect
Feature
Printer operations Perform the following reconnection
when Bluetooth is sequence.
disconnected
[Reconnection sequence]
1. The printer tries to connect to the iOS
device to which it was last connected.
2. When step 1 fails, the printer waits for
connections from other devices.
3. If connection is not established in step 2,
the printer tries again to connect to the iOS
device to which it last connected.
Steps 1 and 2 are repeated until a
connection is established.
Reconnecting to iOS Reconnect automatically.
device
Switch to connection Method 1:
from other device
After disabling the Bluetooth feature of the connected iOS device, make connection settings
on the Bluetooth device that you want to connect.
(When the auto reconnect feature is enabled, it may take some time to connect.)
Method 2:
After disconnecting from the connected iOS device using applications with the TM Utility or
Epson ePOS SDK disconnection feature, make settings on the Bluetooth device you want to
connect.
∗ In the following situations, even if the feature is enabled, the same operations are performed as when it is disabled.
- When the last Bluetooth device connected was not an iOS device.
- When wireless communication settings are initialized from the printer.
- When the Bluetooth connection is cut from the "Printer Selection" screen of the Epson TM Utility.
- When the Bluetooth connection is cut using disconnectDevice API for Epson ePOS SDK for iOS.
∗ We recommend disabling this feature when using the printer from devices that are not running iOS.
∗ When using a single printer between multiple iOS devices, disable this feature to prevent unintended reconnections via Bluetooth.
Otherwise, if you cut the Bluetooth connection using disconnectDevice API on an iOS device that stopped using the printer, the
connection will just be restored when the printer is restarted.
∗ For instruction on how to enable or disable the auto reconnect feature, see
Enabled
"Interface Setup Mode (Interface Setup)" on page
