View SDP

View SDP is an application for Symbian phones which allows you to use Bluetooth Service Discovery Protocol to discover what services another Bluetooth device supports. Available on OVI store now.

Service Discovery Protocol (SDP) is part of the Bluetooth Standard.


This is useful for:
Software developers working with Bluetooth.
Students and teachers studying Bluetooth.
Anybody who is interested in understanding the details of Bluetooth.

Operation

First search for a nearby Bluetooth device to read using the menu options “Search for devices”. Make sure that the device you are using is in discoverable mode. Select a device and a list of Service Discovery Records will be displayed. You can then select a record (either by touch or using the centre key) and the contents of the record will be displayed. For more details on the meaning of the record see the Bluetooth Specification at www.bluetooth.com.

You can also save the SDP data as a text file on your phone using the menu option “Save SDP data to file”. The text file will be stored on your phone in C:/data/others/SDP_xxxx.txt where xxxx is the Bluetooth name of the device.

FAQ

This application is for all Symbian phones from 3 edition FP1, including FP2 and edition 5.
