    Overview of the CM52 Module The CM52 is a dual band CDMA/AMPS 800 MHz and CDMA 1900 MHz transceiver module. It is designed for consumer and OEM industrial voice and data applications. At this time, the SEMC customer base requires data only applications;...

  • Page 18: Over The Air Service Provisioning (Ota)

    Spectrum Systems. Over the air programming is a mechanism that enables service providers to program mobile equipment (ME) to match their network requirements. For the CM52, OTA is typically used to update NAM values, download a PRL, update the A-key, etc.

  • Page 19: Service

    3.4.2 Scanning If the CM52 is not on the most preferred service in the PRL, the CM52 will periodically rescan looking for better service. Note: the SID/NID list in the latest Qualcomm code no longer designates the most preferred service. A rescan for the most preferred service also will occur any time a traffic channel has been released if the last used SID was not the most preferred.

  • Page 20: Roaming

    AMPS Home SID and CDMA SID/NID list entries are considered home and take precedence over the PRL value. Carriers may alter what the roam indicator in the PRL is defined to be: home or roam. The CM52, however, will always report the roaming indicator as follows: 0 –...

  • Page 21: Phase 2 Or Location Determination

    The module reports incoming messages that are received over the air interface. The CM52 is not designed to store SMS messages. Message storage is a requirement that is handled by the application. Therefore, the CM52 will not store outgoing messages at all. Because the module does not store...

  • Page 22: Data Functionality

    Async data is data communication over a dedicated traffic channel. The host application/user communicates with CM52 by using AT commands to set up the data link and switch to on-line mode once the communication is established. The escape sequence of +++ is used to switch to off-line mode. Note the escape sequence has a guard time of 1 second before and after the +++ is issued, otherwise the unit will NOT switch to off-line mode.

  • Page 23: 1Xrtt

    There is a shared packet data channel upon which several users are sending packets. The interface between CM52 and the host application is PPP, just as it was in the QNC case, but the air interface is different.

  • Page 24: Application Wake-Up

    1/198 17-4/FCP 101 3045 Uen Application Wake-up The wake-up mechanism is a feature provided by the CM52 where the CM52 can remain powered on and function as a module without the host application being powered on. This type of configuration is primarily done for power consumption purposes.

  • Page 25: Ring Indicator Notes

    Real Time Clock (RTC) The real time clock is a feature provided by the CM52 that allows the module to sleep and wakeup for a definable number of cycles, as configured by the host application. This feature is an optional hardware feature that is controlled by software.

  • Page 26: Aeris Microburst

    Time duration of eight minutes would be considered abnormal; however in following with the power down requirements of the CM52 waiting for the shutdown complete message before power can be removed can be costly in terms of power consumption.

  • Page 27: At Commands

    The communication from the host application to CM52 is synchronous: the host application has to wait for a result code before issuing the next command. The behavior of the CM52 is undefined if a new command is issued before the previous command’s result code is returned. The communication from CM52 to the host application is both synchronous and asynchronous.

  • Page 28: Command Format And Syntax

    (S3), then it checks to see if they match the editing character (S5). This ensures that these characters will be properly recognized even if they are set to values that the CM52 uses for other purposes. If S3 and S5 are set to the same value, a matching character will be treated as matching S3 (S3 is checked before S5).

  • Page 29: Output Response Syntax

    1/198 17-4/FCP 101 3045 Uen AT*ESCAN=1<CR> In the example above, AT is the prefix. The CM52 module expects all commands to begin with the letters “AT” or “at”. If the host application inadvertently begins a command with characters other than “AT” or “at”, the CM52 ignore the characters and will not echo them.

  • Page 30: Unsolicited Message Syntax

    4.1.3.5 Unsolicited Message Syntax The CM52 cannotify the application of events as they occur. There are two types of unsolicited messages: those that the module will always report and those that are optional. The optional unsolicited messages are controlled by the AT command EUNSOL (see chapter 4.2.11).

  • Page 31: Information And Identification Commands

    CM52 and a host The Attention command is used to determine the presence of CM52. The result code “OK” is returned if the module is ready to receive AT commands. If the module is not ready, there is no response.

    This unsolicited response indicates that an incoming SMS message cannot be saved because there is no room remaining in the memory on the CM52. Under this condition the CM52 returns a NACK to the network. The network keeps the message and attempts to resend it again at another time. When this unsolicited message is received, all SMS messages stored on the CM52 should be read or deleted.

    This command selects the level of functional capability <fun> in the module. There are two ways of shutting down the CM52 properly. One way is to use this command. The other way is via input pins (see the CM52 Integrator’s Manual, HW description, on how to do this).

If during the wake time a WAKE event occurs, the module toggles the Ring Indicator (RI) output signal according to the WAKE mask setting. See the AT*EWAKESET command for a detailed description of this functionality. Time is defined as UTC time.
  • Page 78 If the module was not in the RTC mode, the command is a no-op. When the RTC hardware option is present in the CM52, it is highly recommended that the application always issue AT+CFUN=1 any time the application starts a session with the module. Not issuing AT+CFUN=1 could cause the module to never power down completely or may modify the sleep cycles defined in AT+CFUN=10.

    It is recommended that the host application issue AT*EWAKE immediately before powering down if the intention is to leave the CM52 powered on. This resets the wakeup reason, and no “old” events are indicated when in fact they did not happen during the time the host application was powered down. This is necessary because the wakeup reason can be set, and the RI pin asserted during normal execution when the host application is powered on.
