!Requirement
!Comment
|-
|Hardware
|A high CPU count promotes better cloud tiering throughout because although object storage can be slow in I/O operations per thread, object storage can support many threads. Any standard x86 64-bit servers can be ideally used.
|-
|Memory Requirements
|Cloud services demand a large amount of memory, which is why the minimum recommended memory size is 8GB.
|-
|Hard disk
|For a medium-sized (up to a 1000 devices) server, 300GB RAID1 disks can be recommended.
|-
|Database
|A database is required to store the records/messages incoming from multiple devices.
Further, this data must be assigned to its appropriate device ( recognized by IMEI ). MySQL can be used for the database.
|-
|Security
|Teltonika devices support TLS Encryption which can be implemented.
[[How to generate TLS certificates (Windows)?]]
|-
|Programming Skills
|Knowledge about programming language is a must. Teltonika Telematics is a hardware production company, we do not provide software programming services and cannot help with writing code for the server. Only consult on the logic and algorithms of device features and possible issues in data interpretation from the server side.
|-
|Hardware Knowledge
|It can be found on our Teltonika WIKI: https://wiki.teltonika-gps.com/view/Main_Page
To understand the devices, their use cases and how they send data.
|-
|Protocol Implementation
|Teltonika Telematics device protocols need to be implemented for the server to understand and parse the received data correctly.
[[Teltonika Data Sending Protocols]]
|-
|Socket Programming
|Sockets and the socket API are used to send messages across a network. For Teltonika devices to make connection to your server, the server needs to have an application socket programmed to accept these connection request.
'''Note:'''
Each socket should be dedicated to one device, this will allow the server to differentiate the devices when more than 1 device is sending data at the same time.
|-
|Network Considerations
|Cloud storage supports storing cold data on a public cloud object storage service,such as Amazon S3. When using a public cloud, the connection is over a WAN.
|-
|Bandwidth Requirements
|Bandwidth speed requirements are based on the amount of data transfer per month. It can be calculated using some online tools such as: https://www.calculator.net/bandwidth-calculator.html.
|-
|IP Address Requirements
|Static IP or a dedicated port and domain is required otherwise device configuration would need to be updated constantly with a new IP or a new Port.

|Currently, the Teltonika devices works with 03 different protocols for Data Sending; TCP, UDP, and MQTT. Please keep a note that MQTT is supported only via AWS server or a custom server which should be implemented based on the AWS protocols. More information on MQTT ( based on AWS ) can be found here: https://wiki.teltonika-gps.com/view/Getting_Started_with_AWS_IoT_Core.

|<strong>Is there any ID/Value available corresponding to the paramters that Teltonika devices offer? </strong>
|-
|Yes, there are several parameters that you can get from our devices and the AVL IDs corresponding to each one of them can be found here: https://wiki.teltonika-gps.com/view/FMM130_Teltonika_Data_Sending_Parameters_ID.

=='''Communication with server'''==

{| class="wikitable mw-collapsible mw-collapsed" role="presentation"
|<strong>How does device communicate with the server?
</strong>
|-
|First, when module connects to server, module sends its IMEI. First comes short identifying number of bytes written and then goes IMEI as text (bytes).
For example, IMEI 356307042441013 would be sent as 000F333536333037303432343431303133. First two bytes denote IMEI length. In this case 0x000F means, that IMEI is 15 bytes long.
After receiving IMEI, server should determine if it would accept data from this module. If yes, server will reply to module 01, if not - 00. Note that confirmation should be sent as binary packet. I.e. 1 byte 0x01 or 0x00. Then module starts to send first AVL data packet. After server receives packet and parses it, server must report to module number of data received as integer (four bytes). If sent data number and reported by server doesn't match module resends sent data.

|<strong>How to setup records sorting from protocols Codec? </strong>
|-
|-
|'''I want to receive the data generated by the Teltonika device, does Teltonika have any server or service for this purpose? In case not, Are there any recommendations on how to proceed to receive the data?'''
|Records can be sorted by using timestamp as a record sorting method, as it allows us to know what record was received early.
|As we are a Hardware manufacturer we don’t count on a server or service that you can use to see the data generated by your device. So we can offer different solutions for you to reach your goals. [SP1]

{| class="wikitable mw-collapsible mw-collapsed" role="presentation"
|<strong>How to setup the answer to the Codec protocols in C#, Java, C++ from the server side, while counting records?</strong>
|-
|-
|'''I want to develop a Vehicle Tracking System using your GPS Tracker. So, my question is what are the required knowledge/skills to set up my server for sending/receiving data to the Teltonika tracker? I am confused about how to set up my server to send and receive the data from the device.'''
|You can write script in your preferred language ( C#, JAVA or Python ) which can extract the number of records received from device and send it as a ACK packet to the device.
|To develop your platform first you must be aware of some sort of information/tech skills, such as device Data Sending Protocols, device data sending parameters, basic concepts of network communications, such as communication protocols, open and test IP and ports and how to parse the data received using source codes or the provide protocols.
|}
=='''Troubleshooting Data'''==
{| class="wikitable mw-collapsible mw-collapsed" role="presentation"
|<strong>How to know if the device is sending the data to server or not? And how to know if the server is accepting the data from device or not?
</strong>
|-
|-
|'''Where can I find a simple and understandable description of the data sent from the device to the server, along with an explanation? I need to understand what the server sees, how it is written, and what the specific values mean.'''
|
#We can always check the Device Status->GSM info page on the Teltonika Configurator. If device' GPRS status is "Activated" and Sent Records count is above zero and the Sent Records count is increasing that means device is sending data to the server. Thereafter, the server has to accept the data and send back response.
#If the server has the Codec 8 protocol integerated properly, it will send the response in HEX as number of records received by server. On Teltonika Configurator under Status->GSM info, we can check the "Received Data", Socket and Last server Response time to confirm when was the last connection happened with server and its response hour.

|<strong>How to make multiple session separation from the server side from different devices?</strong>
|-
|-
|'''I want to create my own program to listen to what the device sends, what are the network protocols used by the Teltonika devices? What I need to configure on my PC to receive the data? How should I know it’s working as expected?'''
|Multiple devices can be separated by recognizing the IMEIs of the devices on the server side. The very first step by the device is to send the IMEI on the server and server receives IMEI and sends ACK packet back to the module. All the modules have different IMEI which can be used as a point of differenciation.
|}
{| class="wikitable mw-collapsible mw-collapsed" role="presentation"
|<strong>How can we know if the acknowledgment is required on the server or not? Can we change this setting?</strong>
|-
|-
|'''After creating my server, I started to receive the same message from the device for multiple times. Should I respond to it? If yes, whats the format of the response?'''
|Acknowledgment is made depending upon the "Record Settings":
#If ACK Type, TCP/IP is selected then Server Acknowledgement is not required
#If ACK Type, AVL is selected then the Server must respond with the Acknowledgement.
|}
=='''Common Mistakes'''==
{| class="wikitable mw-collapsible mw-collapsed" role="presentation"
|<strong>I am getting the error on the server side saying"Protocol Mismatch". What could possible be wrong in this case?</strong>
|-
|-
|'''I have done the IMEI acknowledgment part by sending 01 to the device upon reception of IMEI. Now, having a bit of difficulty in sending the number of data packets received on the server from the FMX device. What exactly should I do to properly respond to the device?'''
|This is because of mismatch in the selection of Network Protocol on the device and server side. It is possible that on the Device, TCP is selected and on the server side its UDP or vice-versa. Since the structure for both the protocols is different, this mismatch can restrict establishing a connection on the server.
|}
=='''Communication over GPRS '''==
{| class="wikitable mw-collapsible mw-collapsed" role="presentation"
|<strong>How can my device communicate over GPRS messages?</strong>
|-
|We have few CODEC protocols supporting GPRS communication: Codec 12,13,14,15. However the functionality basics remains the same and is explained below for Codec 12.
#First, the Teltonika device opens the GPRS session and sends AVL data to the server (refer to device protocols).
#Once all records are sent and the correct sent data array acknowledgment is received by the device then GPRS commands in Hex can be sent to the device.
#The ACK (acknowledgment of IMEI from server) is a one-byte constant 0x01. The acknowledgment of each data array sent from the device is four bytes integer – a number of received records.
Detailed information on the protocol can be found here: https://wiki.teltonika-gps.com/view/Teltonika_Data_Sending_Protocols#Codec_12
|}
=='''RAW Data Example'''==
{| class="wikitable mw-collapsible mw-collapsed" role="presentation"
|<strong>I need to parse the data received on my end. Do you have any piece of code or examples that you can provide that I can use to develop my parser?</strong>
|-
|-
|'''I tried to implement my server but I couldn’t create a tool to listen to the data sent by the device. Does Teltonika have any tools to help in receiving the packets? And to parse the data received? If yes, where I can find it?'''
|Here's an example of the Data Received in the HEX Format and how to parse it:
Received data in the hexadecimal stream:
000000000000003608010000016B40D8EA30010000000000000000000000000000000105021503010101425E0F01F10000601A014E0000000000000000010000C7CF.
The detailed parsing can be found in the wiki page, under the category Communication with server: https://wiki.teltonika-gps.com/view/Teltonika_Data_Sending_Protocols#Codec_8
