1 ExtendedAT Application

1.1 Contents

The ExtendedAT Application 1.21 offers, in a single application, the combination of all AT commands provided by:

  • TCP/IP and Internet: Complete IP connectivity by AT Commands, bringing TCP, UDP, FTP, HTTP and POP3/SMTP services
  • MMS: Ability to send text, photo and/or sound file through Multimedia Messaging Service
  • Location Service: Ability to handle GPS positioning with the combination of AirPrime XM0110 to get NMEA frame, PVT data and TTFF
  • eCall-InBandModem: Ability to manage emergency call and send MSD data to PSAP server through AT Commands
  • Jamming Detection: New AT Commands (AT+WJAM) to detect jamming proximity and its level
  • Network Scan: Ability to monitor and get the best network environment at a given location by AT Command (AT+NWKSCAN), to ease device installation.

1.2 Location Features

  • Host RTC: Location library/XM0110 use the Embedded Module RTC time to build its clock reference. Pay back is BOM saving (extra hardware to generate/maintain the clock is useless) without any TTFF performance degradation.

3 Known Restrictions

3.1 Extended AT specific restrictions

The specific Extended AT known restrictions of this release are:

Id Description (What / When) Impacted Domain Impacted Sub Domain
60393
60399
62949		 Embedded module may reset when TCP data transfer operations are performed while GPS is running over I2C.
Workaround: Increase AHB bus clock to maximum value using AT+WCPS=1,1. Please note that this boost also increases consumption.		 OTHER OTHER
60375 Embedded module may reset if large amounts of TCP/IP based data is displayed on one UART using offline mode feature while GPS based data is displayed over another UART. OTHER OTHER

3.2 Internet Application restrictions

Id Description (What / When) Impacted Domain Impacted Sub Domain
59405 CME ERROR: 837 is received when ‘AT+WIPDATA’ command is issued even without starting a GPRS bearer and creating a TCP/UDP socket. ‘CONNECT’ indication is received in earlier versions of Internet Application. Ideally, CME ERROR: 831 (BAD STATE) should be received in such case. OTHER OTHER

3.3 Location AT restrictions

Id Description (What / When) Impacted Domain Impacted Sub Domain
63248

If task for DEE is not statically declared (see simple sample to get an exemple), error event occurs during start transition or stop.

please notice that start or stop event will occur anyway.

 GPS AT cmd. Others

3.4 Jamming Detection restrictions

Id Description (What / When) Impacted Domain Impacted Sub Domain
None

3.5 Network Scan restrictions

Id Description (What / When) Impacted Domain Impacted Sub Domain
None

4 Interface modifications

API Comment
ATI9 Information for application i.e. Application name, version, and Company Name are now filled in response of ATI9 command.

4.1 Internet Application

All eCall InBandModem AT Commands interface remain identical

5 Corrections & Improvements

5.1 Internet Application

Id Issue Description Fixed In
55455 +CME ERROR: 800 is received instead of +CME ERROR: 851 when Server Address, Username and Password parameters are missing in the internet application command AT+WIPCREATE=4,1 to create the FTP server. 5.54
59087 When trying to set the data representation type at UART2 using Internet Application command AT+WIPOPT=4,1,2,40,x, after the FTP connection is made the expected OK response is not received. 5.54
59200 Unable to open server socket again, after closing the server socket and client socket (in this order). 5.54
