WX 20+ GPS Tracking server

Startbeitrag von Jim Carson am 04.05.2016 16:19

I want to build a application that has GPS tracking. I have found that one needs to create/enroll with a tracking server in order to provide this feature. Has anyone done this? What are the limitations with WX? Any API's work well world wide? I want this to be available via phone....both android and ios and windows phone.

Hi,

3 years ago I began to build such a system, but I stopped because work on another project.

I made a windows service that receives the connections of GPS tracking devices, communicating with each device and writes the received data into the database. I used one of the available commercial GPS devices for monitoring vehicles, and implemented the elementary functionality of the manufacturer's communication protocol.

I hope that I will have the opportunity (time) to complete the project.
I think the WX very suitable for this type (multiplatform) project.

I use units from http://www.atrack.com.tw/
They have a simple protocol (based on the AT modem commands).
The units in the vehicles are programmed to connect to the server using TCP so there is a full communication channel. This allows interrogation etc.
They can also send GPS data via UDP if required.
The (WinDev) server application records the data to a MySQL database.
I then use OpenStreetmaps to visualise this using a browser.
Has been working for over 5-6 years now and very reliable.
Good Luck

Hello, please can anyone give reference to how can i read gprs packets from gps tracker and store the geographic data to database. It would be really helpful.

Hi

it depends of the hardware you use. You will have to check with its manufacturer for the corresponding API/SDK documentation.

Best regards

FACID,123456,GPRS,ADDR=219.133.34.184,PORT=8000,NAME=,PASS=,APN=CMNET,ID=,MODE=0,HBE=0,HBN=HI,HBI=50,HBT=100,HBR=1ADDR: it is your server’s IP.
PORT: your server’s port.
User manual of tracker
- 12 -
12
NAME: access Point’s user name.
PASS: access point’s password.
APN: network service access point.
ID: device number.
MODE: communication mode, 0 means that TCP, 1 means that UDP.
HBE: 1 or 0 enable/disable heartbeat function.
HBN: text message of heartbeat.
HBI: heartbeat transmission time interval.
HBT: The number of heartbeat packets sent (when server receives the number of times
is full, and it didn't feedback, device will restart.)
HBR: When the tracker can't get the server response, whether to restart (reset switch)

This is how the server is configured.

I just need to know how to capture GPRS packets in Windev project

Hi again

from the little you are giving us, I would think with a httprequest

Best regards

How can I get GPRS packet information with httprequest ?
