Document History

Introduction

This document describes how to use the “QCOM” tool. The tool can run without installation. And it supports the following OS:

• Windows 10/Windows 95/Windows 98/Windows 2000/Windows ME/Windows XP

This document is applicable to all GSM, UMTS LTE, and GNSS modules. Install the following tools from the GitHub repository:
LTE & GNSS driver:
5G-NB-IoT/Driver at master · 5ghub/5G-NB-IoT (github.com)
QCOM Tool:
5G-NB-IoT/Tools at master · 5ghub/5G-NB-IoT (github.com)

Install LTE&GNSS Windows Driver

On Windows Operating System (OS), install the following Windows driver for the LTE&GNSS modem:
5G-NB-IoT/Driver at master · 5ghub/5G-NB-IoT (github.com)

Have the Nano SIM ready:

Follow the following steps:

1. Insert a USIM card into the USIM card slot on the hardware board.

2. Connect a USB cable between the hardware board and the computer as in the following diagram (Note: the hardware board is an example and other USB dongles or Raspberry PI HATcan be used. You can also use different antennas if needed)
   If you are using the HAT board with any of the BG96/BG95/EG95/EG91 mini PCIe modules, make sure to insert the SIM card as shown below:

3. Connect the board to a USB cable to the PC, then you shall see the ports and modem in the Windows device manager as in this screenshot:

Use the QCOM tool with BG96/BG95/EG91/EG95

Install the QCOM tool from this location:

5G-NB-IoT/Tools at master · 5ghub/5G-NB-IoT (github.com)

To use the QCOM tool with LTE&GNSS modem, connect the computer USB port to the USB port on the hardware board and make sure all modem serial ports are enumerated in the Windows device manager as in the figure below.
The serial ports below can be used for the following purposes:

• USB Modem: The USB modem interface is used for AT commands, data transmission, GNSS data, and NMEA sentence output.
• USB AT Port: It is used for AT commands and data transmission.
• USB NMEA Port: It is used for GNSS data and NMEA sentence output. Figure 3: Windows device manager enumerated all serial ports of the modem.

Each serial port, as in Figure 3, shows the serial port number uses in the format COMXX. If the USB Modem port is used, you can find its COM port number, by right-clicking on it, selecting Properties, then selecting Modem. You will find the port number displayed for this USB modem. It shows up as COM47 in the figure below. You can use this port number in the QCOM tool.

How to Use the QCOM Tool

The tool is used to send and receive data with a serial port. You can use it to send/receive AT commands, data transmission, and reception, or GNSS control and NMEA sentences
Figure 5 shows the tool when is launched and different controls in the tool.

• The red area displays the received data.
• Blue area displays status information.
• The purple area is used to send data or files.
• The Green area is used to send data continuously.

4.1 COM Port Configuration
According to the connection between the PC and the hardware board, select the right serial port as shown in Figure 6. Select the COM port number corresponding to either the USB AT Port or USB Modem as appears in the Windows device manager and as explained in the previous Sections.

Choose an appropriate baud rate. Please refer to Figure 7.

Choose appropriate Stop Bits, Parity, Byte Size, and Flow Control, shown as in Figure 8.

4.2 Open and Close COM Port
Click Open Port to open the selected COM port. Please refer to Figure 9.

Click “Close Port” to close the selected COM port. Please refer to Figure 10.

4.3 Send Data

To send data from the QCOM tool, follow the following steps:

1. The red area is used to input data that would be sent.
2. The Green area is used to choose the file needed and send a whole file.
3. The Blue area is used to save received data as a file.
4. DTR: Enable the DTR pin of the COM port.
5. RTS: Enable the RTS pin of the COM port.
6. View File: Show the data of the file which has been sent.
7. Show Time: Show the time of each received data.
8. HEX String: The input string is the HEX string.
9. Show in HEX: The received data is shown in HEX.
10. Send with entering: Send data with “Enter”.
11. Clear Information: Clear all received data and status information.
12. Send Command: Start to send the data which you input.
13. Select File: Select the file which would be sent.
14. Send File: Start to send the file that you have selected.
15. Save Log: Select the file in which the Log data was saved.

4.4 Send Data Continuously

To send data continuously, follow the following steps:

1. The red area is used to enable the data to be sent.
2. The Blue area is used to input data that would be sent.
3. The Green area is used to start data sending.
4. Choose All Commands: Enable all available commands which would be sent.
5. HEX: The input string is the HEX string.
6. Enter: Send data with “Enter”.
7. Delay: Delay time for each data.
8. Delay Time: Default delay time.
9. Run Times: The times of sending all selected data continuously.
10. Run: Start to send all selected data continuously.
11. Stop: Stop sending all selected data continuously.
12. Save As Script: Save all data and configure as *.ini file.
13. Load Test Script: Load data and configure from a *.ini file.

Figure 13 shows how to connect the QCOM tool to the USB modem on port COM47. Once you specify the COM port as 47, the Baud rate as 115200, click Open Port. You can exchange AT commands with the modem including registering on a mobile operator network, querying the GPS location, and signal strength.

The following shows more examples of using AT commands.

At the same time, you can launch another instance of the QCOM tool and connect to the USB NMEA Port (COM49). Once you open the port to COM49, you can see all GNSS NMEA sentences output as in the following figure.
