    Because Model 4575 and 4576 use the PTCRB certified Huawei MU609 LGA module, you can also find a lot of useful information from Huawei’s documentation, including information about the command set for controlling Models 4575 and 4576. A link to this documentation is available at www.zoomtel.com/4575support...
  • Page 5 Figure 1   Plugging a micro SIM into the micro SIM slot of the modem First unscrew and remove the case’s SIM cover (Model 4575 only). Plug in a micro SIM at the location shown in Figure 1. The micro SIM can be obtained from AT&T or another modem-compatible service provider.
  • Page 6 You also have the option of supplying power for the modem using the Modem’s header. If you prefer to use the modem’s header, DON”T USE THE POWER CUBE AT THE SAME TIME. For more information about using the modem’s header to power the modem, please see Chapter 7 - Using the Modem’s Header for more information.

    Using SMS Messaging • To learn how to use your modem for GPS, refer to Chapter 6 – Using GPS. • To learn about your modem’s header, refer to Chapter 7 – Using the Modem’s Header. Using the Modem in Linux or Android based Devices Linux and Android users can use either the serial port or USB port to talk to the modem.
  • Page 15 Using the USB port with Linux or Android To use the modem’s USB port, you must first decide which driver you will need to modify. This decision depends on both your application and the kernel version that your application is built on. There are three different drivers that the modem uses: the USB Serial driver, the CDC-ECM driver and the CDC-MBIM driver.

  • Page 17: Establishing A Data Connection

    Establishing a Data Connection This chapter explains how to establish a data connection using either an external protocol stack, the modem’s internal protocol stack, or an ECM connection with your modem. Much of the information contained in this chapter is detailed in the Huawei MU609 HSPA LGA Module Application Guide.
  • Page 18 described in chapter 3. To learn how to connect using an external protocol stack, go to Using an External Protocol Stack to Establish a Data Connection. To learn how to connect with ECM dialing, go to Connecting with ECM Dialing. Using an External Protocol Stack to Establish a Data Connection To establish a connection using the protocol stack that resides on your system is a 2-step process.
  • Page 19 Using the Modem’s Internal Protocol Stack to Establish a Data Connection To send data using the modem’s internal protocol stack, you must be connected to the modem’s serial port, either through the DE-9 connector or the modem’s header. The internal protocol stack does not work over the USB connection. To establish the connection, you must first register the modem on the network for an IP connection.
  • Page 20 only look for one type of data at a time. To set up a listening server using UDP, enter the following command: AT^IPLISTEN=”UDP”, 5008 In this example the modem will monitor UDP port 5008 for data. If it receives data, it responds with the ^IPDATA command.
  • Page 21 are sending data. It can be either an IP address or a web address. Both UDP and TCP are sending data over the same ports with 5005 being the remote port and 5010 being the local port. If the connection is already open, the modem will respond as follows: +CME ERROR: The link has been established already Now that the connections are open, we can send data with the AT^IPSEND command.
  • Page 22 AT^NDISDUP=1,1,”<apn>” Where <apn> is the apn for your service provider. For example, the command to connect to AT&T’s network using the “Broadband” APN is: AT^NDISDUP=1,1,”Broadband” The modem should respond with: ^NDISSTAT:1,,,IPV4 For more information about the AT^NDISDUP command, please refer to the Huawei AT Command manual available at www.zoomtel.com/4575support.

  • Page 23: Using Sms Messaging

    Using SMS Messaging SMS messages are sent to an SMS Center (SMSC), the SMSC uses a store-and-forward technique to try to reach its destination. If a message can not be delivered, it is stored for later retransmission. The maximum size of the message depends on the encoding method used.

  • Page 24: Using Text Mode To Send Sms Messages

    to learn about text mode, you can skip ahead to Using PDU Mode to send SMS Messages Using Text Mode to Send SMS Messages   To send an SMS message in text mode, enter the command. AT+CMGF=1 This sets the modem to text mode. The modem will respond OK. Now, to send the text message enter the command AT+CMGS=“15551234567”.
  • Page 25 AT+CMGF=0 This sets the modem to PDU mode. The modem will respond OK. Before sending a message, we need to understand how a PDU message is built. A PDU message is built using octets, which are 8 bits. The octet can be expressed as 2 hexadecimal digits, such as 7B or A3.
  • Page 26 Length is 2 plus the number of digits transmitted for the SC phone number, as detailed below. When calculating the Length, it’s important to remember that it is expressed in octets; and since each octet is 2 hexadeciimal characters you can count the number of hexadecimal characters in your SCA and divide by 2.

A User Data Header is used for binary content such as ringtones, operator logos, and WAP Push or it is used for concatenated SMS messages to allow longer SMS messages to be sent.
  • Page 29 Because the PDU type octet is in hex, the value for PDU type is 01. Putting that value into our TPDU gives us: Message Destination Protocol Data Validity User User Type Reference Address Identifier Coding Period Data Data Scheme Length 1 Octet 2-12 Octets 1 Octet...

Deleting a Text Message from Memory When you store an SMS message on your SIM card, the modem can be set to present you with the storage location of the message. For example, a text message that is received and stored in memory location 3 of your SIM card would send the following unsolicited command to your application.
  • Page 37 To delete the messages that have been read and have been sent enter the AT+CMGD=1,2. This will delete messages 2 and 4 and will leave message 3 in storage. To delete all messages in storage enter the command AT+CMGD=1,4. This will delete all 3 messages.

  • Page 38: Using Gps

    Standalone GPS relies solely on the GPS satellites, so no data costs are incurred and the modem does not even need to have a SIM card installed. Model 4575/4576 supports A-GPS through Mobile Station Based (MSB) positioning using the user plane protocol. In this mode, the modem receives current information about the orbital data of the GPS satellites quickly over IP from the network.

  • Page 39: Xtraone Mode

    AT^WPDOM=4 to minimize the amount of data used, or to set AT^WPDOM=2 to minimize TTFF.   XTRAOne Mode   XTRAOne Mode is an assisted GPS mode that downloads data from a Qualcomm server once a week and stores the data on the modem. The modem relies on the stored data instead of talking to the network to find positioning info.

  • Page 40: Setting The Modem Up For Gps

    If set to the default mode of GPS only, the following NMEA commands are supported: $GPGGA – Basic GPS NMEA message that provides position and accuracy data $GPGSA – Detailed Dilution of Precision (DOP) and satellite tracking information $GPGSV – Provides detailed information on the satellites in view including location and signal quality.

    Using Standalone GPS   If you have not already installed your hardware, you should do that now. Please see Chapter 2 - Installing your ZoomCell modem if you need help. Since you are using standalone GPS we recommend setting the modem to GNSS mode to take advantage of both the GPS and GLONASS satellites.
