If you have the on-screen keyboard popped up while the RFID Sensor is
typing, it will activate any auto-completion features, as if you had typed
on the on-screen keyboard. This can be slow, so dismiss the on-screen
keyboard if you have a lot of data coming from the Sensor.

RFID Sensor Demo Instructions

1. Make sure there is no USB cable connected to the “USBOTG” interface. It is OK if a

cable is connected to the DEBUG (Console) interface. After pairing, the xPRESS
platform will identify itself as a keyboard to the host. Wait for the host to recognize the
interface as an HID device.

2. Open a host application that can accept text

Press the “User Switch” button to start reading.

The RFID Sensor application automatically adjusts the module RF output levels. If
powered by USB or battery, the module will be set to +20 dBm. If powered by AC or
POE, the module will be set to +30 dBm.

The blue LED will be on whenever the module is reading.

3. The yellow LED will flash and the buzzer will chirp whenever a tag is found. If the tag

buffer becomes backed up, reading will slow down (this is common when the
Bluetooth module is used as its interface speed as an HID device is considerably
slower than the USB connection).
