BluetoothGPS

This is a Python module receiving GPS readings or cell tower information over Bluetooth or directly from mobile phone, and save formatted data into MySQL database for further analysis. The project was ever tested on Symbian smart-phones.

How to decode GPS reading?

GPS readings can be obtained from the sentences sent by receivers. For example, the following sentences sent by NMEA GPS receiver contain GPS longitude and latitude information and can be decoded:

• GPGGA
• GPRMC
• GPGLL

How to get GSM location?

Retrieves GSM location information: Mobile Country Code, Mobile Network Code, Location Area Code, and Cell ID. A location area normally consists of several base stations. It is the area where the terminal can move without notifying the network about its exact position. mcc and mnc together form a unique identification number of the network into which the phone is logged.

The location module offers APIs to location information related services. Currently, the location has one function:

• gsm_location()

Prerequisite: PyS60 installed

Here is an example of how to use the location package to fetch the location information:

import location

print location.gsm_location()

(525,5,12,55693)

The place is around Jurong west St65.
