is a serial communication and debugging tool primarily provided by
for interacting with GSM, UMTS, LTE, and 5G modules. It serves as a graphical interface for developers to send AT commands and manage data transmission through a PC's COM port. Key Features of QCOM V1.6
The tool is designed for simplicity and does not require installation to run. Its interface is divided into functional zones: Data Monitoring
: Displays received data (Red area) and real-time status information (Blue area). Transmission Control
: A dedicated input area for sending data or entire files (Purple/Green areas). Automation
: Supports "Send Data Continuously" mode and the ability to save or load test scripts ( files) for repetitive tasks. Protocol Support
: Handles standard serial parameters including Baud rate, Stop Bits, Parity, and Flow Control (DTR/RTS). GNSS Management
: Includes specific controls for GNSS and NMEA sentence reception. How to Use QCOM V1.6 Port Selection : Connect your hardware to the PC. In Device Manager
, identify the correct COM port number (e.g., COM47 for a USB Modem). Configuration
: Open the tool and select the identified Port and appropriate Baud rate. Connection to establish the link. Interaction : Type AT commands into the input field and press
(or use "Send with Enter"). The responses will appear in the monitoring window. Downloading the Tool Official versions should be sourced from the Quectel Download Zone
to ensure software integrity. While older versions like V1.6 are widely archived on developer forums, using the most recent version from the manufacturer is recommended for compatibility with newer 5G modules. Note on "QCOM 1.6" in Other Contexts The term also refers to the QCOM Protocol Version 1.6
, a regulatory specification used by the Queensland Government for electronic gaming machine (EGM) monitoring.

QCOM V1.6: The Essential Serial Debugging Tool for IoT Modules
QCOM V1.6 is a portable serial port debugging tool developed by Quectel for engineers and developers working with GSM, UMTS, and LTE modules. Unlike complex flashing software, QCOM is a lightweight utility designed specifically for sending and receiving data through serial ports, making it the industry standard for executing AT commands on IoT hardware. Key Features of QCOM V1.6
Despite its small size (under 1MB), the tool provides a comprehensive interface for module communication:
No Installation Required: It runs as a standalone executable on Windows, making it ideal for quick field testing.
Visual Data Monitoring: The interface is divided into functional zones:
Red Area: Displays all received data from the connected module. Blue Area: Shows real-time status information.
Purple Area: Used for sending individual strings or data files.
Green Area: Facilitates continuous data transmission for stress testing.
Broad OS Compatibility: While optimized for modern Windows versions, it maintains legacy support for older operating systems like Windows XP, 2000, and even 98. How to Download and Set Up
You can find official and community-hosted links for the tool below:
Official Source: Registered users can download the tool directly from the Quectel Download Zone or via direct repository links provided in the Quectel Forums.
Community Mirror: A ZIP version is often hosted on platforms like DriveHQ for quick access. Hardware Setup Steps:
Insert SIM: Place a USIM card into your hardware board’s slot. is a serial communication and debugging tool primarily
Connect USB: Use a USB cable to connect your hardware (such as a Raspberry Pi HAT or USB dongle) to your PC.
Install Drivers: Ensure you have the LTE & GNSS Windows Drivers installed so the PC recognizes the COM port. Usage Guide: Sending AT Commands Once the tool is running and your device is connected:
COM Port Configuration: Select the correct COM port assigned to your module and set the appropriate Baudrate (usually 115200 for most modern modules). Open Port: Click the "Open" button to begin the session.
Execute Commands: Type AT commands in the Purple input area. For example, type AT to check for a basic "OK" response, or ATI to see module identification details. QCOM vs. Other Qualcomm Tools
It is important to distinguish QCOM V1.6 from other software in the Qualcomm ecosystem:
QFlash: Specifically for flashing or installing stock firmware.
QFIL (Qualcomm Flash Image Loader): Used for deep software repairs and unbricking devices in EDL mode.
QCOM Smart Tool: A third-party tool by FuriousGold used for unlocking mobile phones.
For most IoT development tasks involving module configuration and signal testing, QCOM V1.6 remains the most efficient choice for direct serial communication. How to get Driver & Tools - Quectel Forums
The Quectel QCOM Tool is a specialized serial debugging utility used primarily for testing GSM, UMTS, LTE, and GNSS modules via AT commands.
User Manual: You can access the QCOM User Guide (PDF) via the Quectel Forums, which explains how to configure COM ports, baud rates, and send/receive data. Key Features:
Serial Port Debugging: Sending and receiving data via a serial port.
Scripting: Saving configurations and data as .ini files for automated testing. Corrupted Qcom binaries can send malformed Sahara or
File Transfer: Sending entire files or saving received data directly to a file.
Download: While official downloads are often hosted in the Quectel Download Zone, some community versions are hosted on platforms like DriveHQ. 2. Queensland Gaming Protocol (QCOM V1.6)
In the context of Australian gaming regulations, QCOM refers to the Queensland Communications Protocol for Electronic Gaming Machines (EGMs).
Protocol Specification: The QCOM Protocol V1.6.6i document provides the technical requirements for monitoring services in gaming venues.
Operating Procedures: There are specific manuals for Site Controller Operating Procedures that detail how systems handle event logs, power-up procedures, and EGM configurations under version 1.6. QCOM site controller operating procedures
Corrupted Qcom binaries can send malformed Sahara or Firehose protocol commands. The result? A permanently bricked device that even JTAG cannot restore.
Golden Rule: Never run an untested Qcom V1.6 download on your main repair machine or a client’s device.

| Issue | Likely Cause | Solution |
|-------|--------------|----------|
| COM port not found | Missing Qualcomm HS-USB driver | Install QCUSBSerial driver from QDART package |
| Connection fails | Device not in DIAG mode | Ensure firmware has DIAG enabled (e.g., adb shell setprop sys.usb.config diag,adb) |
| Wrong chipset version | Using V1.6 with unsupported newer chipset | Check QDART release notes for chipset compatibility |
| “QCOM.exe not found” | Incomplete installation | Re-run installer and select QCOM explicitly |
