Siemens MC55 AT AT+CEER Extended Error Report, At+Ceer=?, +CEER locationID, reason, ssRelease

3.4AT+CEER Extended Error Report

AT+CEER returns an extended error report regarding the reason of the last

•call release

•failure to set up a call (both mobile originated or terminated)

•failure to modify a call by using Supplementary Services

•failed attempt to activate, register, query, deactivate or deregister a Supplementary Service

•unsuccessful GPRS attach or unsuccessful PDP context activation

•GPRS detach or PDP context deactivation

The release cause report is presented in numeric format. Default output in case of a none-error-situation is +CEER: 0,0,0. A description associated with each number can be found in the tables given in the following sub- clauses and the relevant GSM specifications.

The first parameter <locationID> serves to locate the other two parameters. Depending on the failure or release cause either <reason> or <ssRelease> are applicable, i.e. if <reason> ≠ 0, then <ssRelease> = 0. Vice versa, if <reason> = 0, then <ssRelease> may be ≠ 0.

AT+CEER is not available for data calls, please use ATS18=1 instead. In case of loosed net coverage, MC55 will disconnect the call but no network release cause is available and the default output will still be given out.
