Cellular_CommonGetRegisteredNetwork API return undefined value

[KeitaKashima]

Hi, I called the Cellular_CommonGetRegisteredNetwork API to test MCC when disconnecting the PDN of the network of cellular.

Then I found the API got the undefined value of MCC.

The reason is that the below pOperatorInfo value is not zero clear after getting Malloc.

cellularOperatorInfo_t * pOperatorInfo = ( cellularOperatorInfo_t * ) Platform_Malloc( sizeof( cellularOperatorInfo_t ) );

FreeRTOS-Cellular-Interface/source/cellular_3gpp_api.c

Line 1779 in 7c80e21

cellularOperatorInfo_t * pOperatorInfo = ( cellularOperatorInfo_t * ) Platform_Malloc( sizeof( cellularOperatorInfo_t ) );

The *pOperatorInfo value is copied undefined value below the lines.

FreeRTOS-Cellular-Interface/source/cellular_3gpp_api.c

Line 1807 in 7c80e21

( void ) memcpy( pNetworkInfo->mcc, pOperatorInfo->plmnInfo.mcc, CELLULAR_MCC_MAX_SIZE );

@KeitaKashima
Cellular_CommonGetRegisteredNetwork requires the port to set to the numeric format in Cellular_ModuleEnableUrc. If the format is set to other format, for example long or short format, the MCC and MNC won't be updated and the value is undefined. This is probably the problem you encountered.

We address this issue in #161 to set the format in atcmdUpdateMccMnc in order not to rely on the port initialization code.
