Source code organization :

Whether for modem or gnss, the class methods are numbered according to the chapters in the documentation.

class QuectelModemATCommands:
    # Extract
    def generalCommands201DisplayProductIdentificationInformation(
        self,
    ) -> tuple[bool, list[str]]:
        """
        General commands 201: Display product identification information.

        :return: Tuple containing the status of the command and the response.
        :rtype: tuple[bool, list[str]]

        return self.sendCommand("ATI")

generalCommands201DisplayProductIdentificationInformationgeneralCommands201DisplayProductIdentificationInformatio is the method name:

• generalCommands is the chapter name in the documentation.
• 201 corresponds to chapter 2.1 in the documentation.
• DisplayProductIdentificationInformation is the title of the chapter in the documentation : "Display product identification information".

## Installation
Install the package using `pip`:

```bash
pip install quectelatcommands

Usage

This package provides two main classes and corresponding CLI tools:

1. QuectelModemATCommandsCLI: For interacting with Quectel modems.
2. QuectelGnssATCommandsCLI: For GNSS (Global Navigation Satellite System) configurations.

Python API

QuectelModemATCommands

This class allows you to send AT commands to a Quectel modem for various configurations and operations.

Example:

from quectelatcommands import QuectelModemATCommands

# Initialize with default port and baudrate
modem = QuectelModemATCommands("/dev/ttyUSB2", 115200)

# Open connection
modem.open()

# Send a command to display product identification information
status, response = modem.generalCommands201DisplayProductIdentificationInformation()
print(response if status else "Error sending command")

# Close connection
modem.close()

Available Methods in QuectelModemATCommands (Examples):

• generalCommands201DisplayProductIdentificationInformation: Displays modem information.
• packetDomainCommands1015PacketDataCounterWrite: Configures packet data counters.
• statusControlCommands40314RiSignalOutputCarrier: Sets the RI signal output carrier type.

Refer to the class documentation for a full list of available AT commands.

QuectelGnssATCommands

This class provides GNSS-specific AT commands for configuring output ports, enabling or disabling NMEA sentence acquisition, and more.

Example:

from quectelatcommands import QuectelGnssATCommands

# Initialize with default port and baudrate
gnss = QuectelGnssATCommands("/dev/ttyUSB1", 115200)

# Open connection
gnss.open()

# Configure the output port for NMEA sentences
status, response = gnss.configureGnss2201ConfigureOutputPortOfNmeaSentencesWrite("usbnmea")
print(response if status else "Error sending command")

# Close connection
gnss.close()

Available Methods in QuectelGnssATCommands (Examples):

• configureGnss2201ConfigureOutputPortOfNmeaSentencesWrite: Sets the output port for NMEA sentences.
• configureGnssEnableDisableNmeaSentencesAcquisition: Enables or disables NMEA sentence acquisition.

Refer to the class documentation for a complete list of available commands.

Requirements

This library requires the following dependencies:

• pyserial: For handling serial communication with the Quectel modem/GNSS devices.
• click: For building the command-line interfaces.

License

This project is licensed under the GNU General Public License v3.0. See the LICENSE file for more details.

Additional Information

For more details on the AT commands used by this library, please refer to the official Quectel AT command documentation provided by Quectel for your specific modem or GNSS device model.

Troubleshooting

If you encounter issues with serial communication:

• Ensure the correct permissions are set on the serial device (e.g., /dev/ttyUSB2).
• Verify the serial port and baud rate match those required by your Quectel device.

Known Limitations

Given the large number of possible AT commands, the classes are not fully tested. If you find bugs, don't hesitate to correct them by submitting a PR.
