Hardware
The user can realize specific functionality by software for the TR module. Application for TR module inside can also be developed using the CK-USB-04 development kit. For detailed information refer to CK-USB-04 User's guide.
Power supply
GW-USB-04 is intended to be supplied via USB connector from PC.
Reset
Reset can be invoked by connecting a disconnected GW to USB or by the Reset USB Device command in CDC mode. Actual reset is executed ~5 s after the command is issued. This delay allows to disconnect USB communication on PC side in time.

USB
•
The device supports two USB modes:
Custom Device mode
Full communication with the IQRF IDE is enabled in this mode. The GW uses identical USB driver like e.g. CK-
USB-04. It is possible to upload the application into internal TR module, display data received from SPI interface of the TR in IQRF IDE Terminal etc. The user can easily create his own PC program using the mpusbapi.dll library. See USB Custom Device Example on IQRF website.
CDC mode
After connecting to PC a virtual serial port is created in this mode. The user can create his own PC program and communicate via this port using the protocol described in document CDC implementation in IQRF platform.
•
Switching between the modes:
From Custom Device to CDC:
Using IQRF IDE v2.08 or higher:
Help → Show IQRF USB Device Info → Switch to CDC mode.
•
From CDC to Custom Device:
Using the Switch to USB Custom Class command in CDC protocol.
Current mode indication see chapter LED. The last selected mode is restored after start-up or reset.
Tip
For testing a communication in CDC mode various SW terminals operating with PC serial ports are available. Select a terminal enabling to issue direct byte commands and data. Refer to the communication protocol described in CDC
Implementation in IQRF USB devices User's guide.
Recommended terminal: Docklight, www.docklight.de. There is a project containing all supported commands for this terminal available at www.iqrf.org/218. It is necessary just to select the COM port used.
Unsuitable terminal: Windows Hyperterminal, Tera Term.

LED3 dedicated to the GW – red
LED3 flashes for 500ms after reset.
LED3 flashing in 1 s period means CDC mode (Custom Device mode is without flashing).
LED3 flashes 3x after clicking the IQRF logo in respective IQRF IDE (to identify the kit among other IQRF USB devices in case of multiple IQRF IDE instances).
LED3 flashing in 300 ms period means missing firmware (see Software below).
LEDs dedicated to TR module – LED1 (red) and LED2 (green).
TR module
Wireless IQRF transceiver module compatible with TR-52B, 868 MHz as well as 916 MHz, without temperature sensor.
Antenna
PCB antenna on GW board.
Software
Firmware for the MCU inside the GW is fixed but can be upgraded by the user using the code provided by IQRF manufacturer. Refer to IQRF Application note AN008 – Firmware upgrade for details.
TR module functionality is fully user programmable. Factory default is E03-TR (one of basic IQRF examples).
Programming and uploading the code is similar to CK-USB-04.
