mdot/xdot

[benmessaoudimene@outlook.com]

hi everyone
I want to build a lorawan sensor to connect with “MultiConnect® Conduit® IP67 Base Station IP67 Conduit for Outdoor LoRa® Deployments (MTCDTIP Series)”
which microcontrolor can be used with those module?
also I could not see the difference between the two modules mdot and xdot ,
i want to choose the one which gives me possibility to connect digital and analog sensors.
best regards

mDots and xDots

Both units are able to communicate via serial AT commands. Any micro-controller with a serial peripheral could be used.

mDot datasheet
http://www.multitech.com/documents/publications/data-sheets/86002171.pdf
xDot datasheet
https://www.multitech.com/documents/publications/data-sheets/86002182.pdf

Both modules are programmable and could be connected directly to digital and analog sensors.
https://os.mbed.com/platforms/MTS-mdot-f411/
https://os.mbed.com/platforms/MTS-xDot-L151CC/

Key differences.
mDot has a 100 MHz processor and external flash
xDot has a 32 MHz processor with no external flash

Both have SPI, I2C, digital, analog and serial interfaces.

thanks mr Jason
if I understand, the mDot end Xdot are lorawan module with an integrated CPU so I can consider them as End node in lorawan topolgie , also I can connect directly digital and analog sensors.
can I programme those module and modify it Spreading factor or code rate , transmision power;;; to have an effective communication with the gatweway,
because my mission is to build a new sensor that is performant and can receive and transmit data in long distance into through the building

I found another problem when I search the difference between the mdot and xdot , it is mentioned in web site of multitech that
1-the mdot is for M2M communication and xDot for IoT communication:
https://www.multitech.com/brands/multiconnect-mdot
https://www.multitech.com/brands/multiconnect-xdot
2- here it’s the opposite , the mdot for IoT and xdot for M2M

3 and in 3rd site I found m2m and iot

I do not see the issue with using either term to describe the devices capabilities.

IOT uses M2M communication to provide a service.

IoT vs. M2M – What is the Difference?

[benmessaoudimene@outlook.com]

if I want to define the type of communication between the end device and gateway in the LORA architecture, it is M2M or IoT?

[Jason Reiss]

It is both.

[benmessaoudimene@outlook.com]

How?
is there a document that can help me understand this point
best regards mr Jason

I thought this article has made the point clear.
What are yor questions regarding the contents of the article?

IoT vs. M2M – What is the Difference?

[benmessaoudimene@outlook.com]

I am choosing the adequate components for the design of a sensor that can communicate with a gateway “base station by multitech” already installed.
and when I contacted the community of multitech, he said that I must choose a lorawan module not lora module and he propose mdot and xdot and there is another module “RN2483” it is also a lorawan module;

after when I search about M2M and IoT, I understood that M2M is between nodes and IoT is to communicate with a gateway (transmit data and receive an ACK).

my mission is to build a sensor that can guarantee a long range without the lost of package

[Jason Reiss]

The dots are capable of both.

Lorawan would be used to connect to a gateway.

thanks Mr Jason
please ,Do you have any suggestions for the antenna that I can use with the mdot.
I’m in Europe (868 Mhz) and my sensor will be installed in a building ,
I want to choose a performant antenna wuth a VSWR <= 2
thank you
best regards
