MTK Base Station Information Data

6225 platform, to obtain the base station information, cell_id and LAI
After the settings are completed under Network Setting> network info in engineering mode,
You can output
<MCC>: 460 <MNC>: 00f <LAC>: 80 184
<Cell_id>: 3424
If you want to write it as an interface, you can call it to return information.

Find the source code of the engineering mode in engineermodetracer. C.

{
 Kal_uint8 MCC [3];
 Kal_uint8 MNC [3];
 Kal_uint8 LAC [2];
 Kal_uint16 cell_id;
 Kal_uint8 is_present;
} Mmi_rr_em_lai_info_t;

// Print the Function
Kal_uint8 mmi_em_rr_lai_info_logs (kal_uint8 screen_num, mmi_rr_em_lai_info_t * rr_em_lai_info)
{....}
The function is only used for printing. Search for the function along the output path,
-> Mmi_em_parsing_data (void * info ){...}
-> Setprotocoleventhandler (mmi_em_parsing_data, msg_id_mmi_em_status_ind );

The base station information is transmitted in the info pointer of mmi_em_parsing_data.

Use mmi_rr_em_lai_info_t to perform a strong conversion.

On the MTK platform, I want to obtain the information of the base station, but currently Card 1 is obtained, but card 2 is not (all 0). What is the reason? What should I do?
The Code is as above. I now know that mod_mmi communicates with mod_l4c/mod_l4c_2, but it is obtained through the mod_as module. Is it necessary to change the correct Card 2 to another ID?
There are other methods ....
