Thank you so much for the response sir.
my queries are:
1.I have done tracker with sim 808 and arduino which occupies more space and it has unnecessary
parts and ports in it.so i want to design pcb like yours which has motion sensor,GPS,sim 808. Iwant to embed the board in circular shape with same components that you valtrack V2 has.so sir can you tell me overall cost(assembling and pcb board)for me to build one tracker hardware.
2.I used HTTP to transfer from sim808 to webserver.I designed app to display tracking in maps.It is working fine.My doubt is that is 2G enough for this or 3G is required?(if required then which sim version to be used).
3.Instead of battery your module has the usb connector port to charge the battery.Is that the only to to charge the battery or
we can use the module without battery with just usb port.
1.I would like to know among all the different sim modules like 800L,808,900. What is the best sim module we can use for GPS tracker(if data is transferred using HTTP).
2. Transferring coordinates using HTTP is the best practice for GPS tracker? If it is not then what is the best way?
3. If i have to order my design of hardware to pcbpower. How should i tell my design details and how can i know that my design will work after its delivered. Please tell me the steps how to order my design and how to make sure that it will work fine.
Thank you sir,
All three modules are fine and perform the same when used with HTTP. But SIM808 has GPS/GNSS built in and SIM800L and SIM900 do not. And all SIM800 series including SIM808 and SIM800L are having bluetooth in it.
There is no best way, it depends on your server backend requirements. I find HTTP to be less power hungry as we can quickly send data using built in commands. When using MQTT over TCP it needs more commands to connect and send data and difficult to debug because of its binary nature.
No one can guarantee that your design will work except you
You send PCB power the Gerber files in RS274x format and they will deliver the PCB to you.
Sir, MQTT or HTTP which is the best way to use in tracker for sending coordinates. Is there any efficient and low cost way for tracking other than these two.
2.What did you use for valtrack v2(HTTP or MQTT)?
MQTT is better for short interval fast communication. HTTP takes time and more data and suitable for higher intervals >10seconds.
VALTRACK-V2 supports MQTT and HTTP. Selectable by an Android Application.
But all servers won’t support MQTT. HTTP is the standard for API’s.
