Determining Cell IDs, Signal Strength etc. in Cell Phones

Hi,
I am a newbie to Symbian OS C++ Programming. I recently saw a posting on the Nokia website regarding a tool miniGPS that they have built for the Series 60 I think. Can someone tell me how is it possible to extract the Cell ID (that is the current Cell to which the phone is logged in), Signal Strength and other info from the Cell Phone using Symbian OS C++ and/or J2ME (MIDP Java). This is possible since Nokia's miniGPS uses this but what are the APIs/Functions/Methods etc. that should be used to get this info? Nokia's site has only the compiled code but no source  So anyone with any idea as to how to do this, pls do tell me. Thanx a lot. Regards, RAL. |

check the nokai site again, I wrote a samll sample code to get the cellID there, that should get you started and by checking the header files you should also be able to find a solution for getting the other informations you are requesting.

i don't know whether i am missing something or not but am facing the following problem.
i have series 60 sdk 6.1 by nokia installed on my comp. when i go throught he documentation and class hierarchy, i am unable to find the classes : RBasicGsmPhone, MBasicGsmPhoneNetwork and TCurrentNetworkInfo.
Since i do not have a phone right now, i was just thinking of going through the code of the above classes as u suggested so that i could find out ways of getting the info. But in the SDK documentation at least, these classes do not exist. Am checking the files now. Can u suggest something. thanx, rahul.

it seems that these classes i mentioned are there in .lib files but i cannot find any header files for these. ie cannot find any source nor documentaion for the same. any help is welcome. thanx, rahul.

The header file you are looking for is etelbgsm.h. You can find it from Nokia 9200 SDK at least in some older versions. Or you can search with google and find that some people have put it downloadable in the net.
You might encounter header file etelgprs.h missing also. that one you have to do by you self by writing following lines to text file:
#ifndef __ETELGPRS_H__
#define __ETELGPRS_H__
class RGprs : public RTelSubSessionBase
{
public:
enum TSmsBearer
{
ESmsBearerGprsOnly,
ESmsBearerCircuitSwitchedOnly,
ESmsBearerGprsPreferred,
ESmsBearerCircuitSwitchedPreferred
};
};
#endif
hopet his gets you back on track.

am using ur code from the nokia forum site. since have not bought a phone till now so not able to test it. but i checked out etelbgsm.h and from that it seems that the following lines should be as i have written them.
aLocation = NetworkInfo.iLocationAreaCode; /* INITIALLY aLocation = NetworkInfo.iNetworkInfo.iLocationAreaCode;*/
aCellId = NetworkInfo.iCellId; /* INITIALLY aCellId = NetworkInfo.iNetworkInfo.iCellId;*/
But since one user has got this to work, so am confused till I check on the phone itself. But can u tell me, am I missing something here. thanx a lot. cheers, coolral.

thank you for pointing this out. Propably just my mistake. I infact just wrote it and put it there, newer indeed testes it, so I quess I left those there by mistake.

Could you copy the error messages here, so I could see which objects are cousing you to have unresolved externals ?
