Vehicle Tracking System- Loss of SMS
Posted on 2004-10-16
I have developed an apllication for Vehicle Tracking using Short Messaging service(SMS). I have installed a TC35i module with a computer as modem and the vehicle unit has also been developed around TC35i module with GPS along with it. the computer programming is in VB6.0
The problem I facing is that when I install my Vehicle unit in a vehicle I lose a number of SMS (for example if the vehicle unit sends 50 SMS to the modem, the modem receives only about 40 SMS and the rest are lost). However, if I install the vehicle unit in the same or adjacent room as the modem there is no loss of SMS.
Can somebody help???
