Example:

You enter the correct PIN2:

Enter:

AT+CPIN2=“1234“

GSM module:

OK

You enter an incorrect PIN2:

Enter:

AT+CPIN2=“1234“

GSM module:

+CME: ERROR: WRONG PASSWORD

AT+CPWD - Change password

This command allows you to change the password. Since more than one password will be available for future uses, you must specify the name of the password upon entering it.

 

AT+CPWD

 

 

Command

Result

 

 

AT+CPWD=?

Displays a list of the passwords supported. These cur-

 

rently include the PIN, device code and PIN2.

 

 

AT+CPWD=<name>,

This command instructs the GSM module to change the

<old password>,

relevant password. When changing the password, you

<new password>

must enter both the old and new password. This ensures

 

that changes can be made only if access is authorized.

 

 

Example:

 

 

 

Enter:

AT+CPWD=?

Requests the list of passwords (SC = SIM,

 

 

 

PS = device code, P2 = PIN2)

GSM module:

+CPWD: (“SC,8“,“PS,8“, “P2,8“)

 

 

OK

 

Enter:

AT+CPWD= “sc“,“1234“,“4321“

GSM module:

OK

Password was successfully changed.

The following result code is returned if the old PIN you enter is incorrect:

Enter:AT+CPWD= “sc“,“0123“,“4321“

GSM module: +CME ERROR: INCORRECT PASSWORD

The password was not changed because the old PIN was incorrect.

M1 specifications

The Siemens M1 is a prominent urban transit solution designed for efficient and sustainable public transportation systems. This innovative metro train has become a staple in various metropolitan areas, known for its balance of performance, safety, and passenger comfort.

One of the key features of the Siemens M1 is its modular design, which allows for flexibility in configuration depending on specific transit needs. The train typically consists of multiple carriages that can be adjusted for length and capacity, accommodating different passenger volumes while minimizing operational costs. This adaptability makes the M1 ideal for growing urban environments where ridership numbers can fluctuate.

The Siemens M1 is built with advanced technologies that enhance its operational efficiency. It utilizes a lightweight construction, primarily through the use of aluminum, which reduces energy consumption while still maintaining structural integrity and safety standards. The train is also equipped with cutting-edge traction systems that ensure smooth acceleration and fast braking, resulting in a comfortable ride for passengers.

Safety is a paramount concern in transit systems, and the M1 incorporates various safety technologies. It features advanced signaling systems that enhance communication between trains and trackside equipment. Moreover, the train is designed with anti-collision measures and real-time monitoring systems that can detect faults before they lead to service disruptions.

Passenger comfort is another critical aspect of the Siemens M1 design. The interiors are spacious and feature modern seating arrangements, allowing for easy movement within the train. Large windows provide natural light and views of the outside environment, contributing to a more pleasant travel experience. The train also offers features like climate control, information displays, and accessibility options for passengers with reduced mobility.

Environmental sustainability is an integral part of the Siemens M1’s design. It is tailored to reduce carbon emissions, featuring energy-efficient systems that lower the overall ecological footprint. Additionally, the train can be integrated with renewable energy sources, further promoting green public transport initiatives.

Overall, the Siemens M1 stands out as a versatile and efficient urban transit option, combining modern technology and design principles that cater to the needs of both operators and passengers. With its focus on safety, comfort, and sustainability, the Siemens M1 continues to play a vital role in shaping the future of urban mobility.
