Application note 16 updating mc75i firmware
AT CMEE=1 Enable numeric error codes (the error response includes a value to indicate the detail of the error in question. AT CMEE=2 Enable verbose error code (the error response includes a text string describing the error situation. 2.3 Using Extended Error Reporting Many modem vendors support extended error reporting so that additional information can be sent when an problem occurs.
For example, if a PDP Context Activation fails, it may be possible to obtain additional information on the reason for the failure.
Thus, some modem makers may support only a subset of the standard AT Command set.Cellular connectivity of machines is fundamentally changing both our daily lives and whole industries.While the advantages of wireless connectivity over fixed line are significant, how these devices are designed requires additional sophistication in application logic.These modems are controlled by the application through a set of Attention (AT) Commands.Standard AT Commands for controlling wireless modems are defined in the following specifications: 3GPP TS (3rd Generation Partnership Project; Technical Specification Group Terminals; AT Command set for User Equipment (UE)) 3GPP TS (3rd Generation Partnership Project; Technical Specification Group Terminals; Use of Data Terminal Equipment - Data Circuit terminating; Equipment (DTE - DCE) interface for Short Message Service (SMS) and Cell Broadcast Service (CBS)) These documents contain the standard commands for managing modems.
