Pairing (Bluetooth or NFC)
Connecting your KDC using Bluetooth is made easy with the below pairing barcodes.
If using an Android device, pairing via NFC is even easier: just approaching the KDC to the back of the host
device’s NFC area is enough for pairing. For more details, see section 2.3
2.1 Bluetooth Profiles Explained
a. HID Profile: Allows one-way Bluetooth communication with an Android or iOS host
device. The KDC only transmits data to the host device.
b. SPP Profile: Allows two-way Bluetooth communication. The KDC transmits data to the
host device and the host device can transmit data back to the KDC.
c. HID Windows Profile: Allows one-way Bluetooth communication with a Windows PC. The
KDC only transmits data to the Windows PC.
Note:HID inputs data directly into an application. SPP requires the KOAMTAC KTSync®
app or integration of KOAMTAC SDK to input data into an application. To gain access to
the SDK, please complete the form here: https://www.koamtac.com/sdk/

above.
•If you desire an SPP connection for any device, then scan barcode #3 above.
c. In HID or HID Windows Profile, check the list of available Bluetooth devices on your host
device. From the list, select the KDC 380 listed by serial number in brackets that matches
the serial number found on the back side of the KDC380. KDC380 will beep upon
connection and display “BLE HID Connected” on its screen. Now it is ready to use.
