This tutorial describes how to get the signal strength information with the telephony API for applications.
#include <e32base.h> #include <Etel3rdParty.h> class CClientApp : public CActive { private: CTelephony* iTelephony; CTelephony::TSignalStrengthV1 iSigStrengthV1; CTelephony::TSignalStrengthV1Pckg iSigStrengthV1Pckg; public: CClientApp(CTelephony* aTelephony); void SomeFunction(); private: /* These are the pure virtual methods from CActive that MUST be implemented by all active objects */ void RunL(); void DoCancel(); }; CClientApp::CClientApp(CTelephony* aTelephony) : CActive(EPriorityStandard), iTelephony(aTelephony), iSigStrengthV1Pckg(iSigStrengthV1) { //default constructor } void CClientApp::SomeFunction() { iTelephony->GetSignalStrength(iStatus, iSigStrengthV1Pckg); SetActive(); } void CClientApp::RunL() { if(iStatus==KErrNone) { TInt32 sigStrength = iSigStrengthV1.iSignalStrength; TInt8 bar = iSigStrengthV1.iBar; } } void CClientApp::DoCancel() { iTelephony->CancelAsync(CTelephony::EGetSignalStrengthCancel); }
