Overview
FMB125 small and professional tracker with internal high gain GSM and external GNSS antennas,
which is able to collect device coordinates and other useful data and transfer them via GSM network
to server. This device is perfectly suitable for applications where location acquirement of remote
objects is needed: fleet management, car rental companies, taxi companies, public transport,
logistics companies, personal cars and so on. FMB125 can perform tasks on remote objects, such as
monitoring engine status, controlling truck’s door etc.
Currently for MQTT solution evaluation firmware is required to be used - 03.27.10.Rev.520.
For firmware supporting MQTT please contact your sales manager or contact directly via Teltonika
Helpdesk.

Set up your Development Environment
Tools Installation (IDEs, Toolchains, SDKs)
FMB125 comes with our created firmware, therefore no additional development or scripting is
required for this unit to support AWS IoT. Only by using Teltonika Configurator FM Configurator
versions, connection point of AWS IoT server is required.
Other software required to develop and debug applications for the device
For debugging situations, device internal logs can be downloaded OTA by using our FotaWEB
platform or by using Teltonika Configurator.
Set up your hardware
All details about FMB125 can be located in our dedicated wiki page FMB125 Wiki

Setup your AWS account and Permissions
Refer to the online AWS documentation at Set up your AWS Account. Follow the steps outlined in
the sections below to create your account and a user and get started:

Sign up for an AWS account
Create a user and grant permissions
Open the AWS IoT console
Pay special attention to the Notes.
Create Resources in AWS IoT
Refer to the online AWS documentation at Create AWS IoT Resources. Follow the steps outlined in
these sections to provision resources for your device:
Create an AWS IoT Policy
Create a thing object
Pay special attention to the Notes.
Provide Device with credentials
Whole device, AWS IoT and testing information can be downloaded in PDF format here.
NOTE: MQTT will not work without uploaded TLS certificates.
AWS IoT Core Configuration
Setting up AWS IoT Core
When logged in the AWS console, click on Services on the top left hand side screen, to access IoT
core.

Figure 1. Accessing AWS IoT core from AWS console
NOTE: If you can't see "Services" in the top left, click on "My account" in the top right and "AWS
Management Console"
Select Manage, Security, Policies (Manage > Security > Policies) and press Create policy or Create
buttons.
Figure 2. Accessing policy creation
In the Create Policy window, enter Policy name. In the Policy document tab for Policy Action (1)
select “*” and for Policy resource (2) enter “*” and press create.
Figure 3. Creating a policy
Now, that you have created a policy, select Manage on the sidebar on the left side, then select All
devices, Things (Manage>All devices>Things). And click on Create things.
Figure 4. Accessing Things
Afterwards select Create single thing and click Next.

Figure 5. Creating single thing
After creating a single thing, enter Thing’s name and in the Device Shadow tab select Unnamed
shadow (classic). Then click Next.
Figure 6. Thing's properties
Then when selecting Device certificate, select Auto-generate a new certificate and click Next.

Figure 7. Certificate configuration
Now, select the policy you have created before to attach it to the certificate and thing. After that
click Create thing.
Figure 8. Attaching policy to certificate
Then window with Certificate files and key files download options should pop out. It‘s recommended
to download all files, because later some of them will not be available for download. The files that
are required for usage with FMX devices are: Device certificate (1), private key(2), and Amazon Root
CA 1 file(3), but it‘s recommended to download them all and store them in secured place.

Figure 9. Certificate and key download
Finding device data endpoint (server domain)
To receive server domain (in AWS endpoint) click on the side bar on the left Settings (AWS
IoT->Settings). Or click on the side bar on left side Things, select the created thing, after it click
Interact->View Settings. Whole path - (Things->*YourThingName*->Interact->ViewSettings). Page
containing endpoint will open. Copy the whole endpoint address. Port for accessing this endpoint is
8883.
Figure 10. Device data endpoint
Configuring the device

Security and certificates
Using certificate, private key and root certificate. (Via Cable)
Find Certificate file ending with extension pem.crt (ending may be just .pem) Private key file and
AmazoonRootCA1 file (no need to change filenames). These files should have been downloaded when
creating Thing in AWS IoT Core.
Figure 17. Certificate, private key and root certificate
Upload the mentioned files in the Security tab in the Teltonika Configurator.
Figure 18. Uploading certificates and keys
After uploading certificates, go to System tab and in Data protocol section select - Codec JSON.

Figure 19. Choosing data protocol
Device GPRS configuration for AWS IoT Custom MQTT settings
In the GPRS tab, under Server Settings select:
Domain – Endpoint from the AWS, Port: 88831.
Protocol – MQTT2.
TLS Encryption – TLS/DTLS3.
In the MQTT Settings section select:
MQTT Client Type – AWS IoT Custom1.
Device ID – enter device IMEI (optional)2.
Leave Data and Command Topics unchanged.3.
Save the configuration to the device.

Checking received data and sending commands in the AWS
IoT core
The data received from the device can be found in the MQTT test client, which can be found above
“Manage” in the sidebar on the left.
Figure 28. MQTT test client location
To see incoming data, subscribe to topic - *DeviceImei*/data . Or subscribe to # to see all incoming
outgoing data in the Topics.
