Here is a link to the full “Flow” created at 5:50 in the video.
This includes LoRaIn Node–>F(n) Node—>Debug Node

And is intended for use with the MTDOT-BOX or EVB when selecting
“LoRa Demo” mode of operation to parse out sensor data.

Thanks for watching

[Steve Kovarik]

Hi Alejandro

Generally speaking you do not need to manually set the operator.
Usually just need to insert the SIM and the “preferred network list”
is read off the SIM.

+CME ERROR 529 is a valid response for that command that indicates
Selection failed – emergency calls only.

Hi Alexey

The MTCDT-STARTER-KIT-868 has a MSRP of $899 USD and is available
through our distribution channel. Where are you located?

[Steve Kovarik]

In the DeviceHQ app store the DotBox-Google app writes to the SD card.

Also, here’s an AEP Node Red Flow that writes “LoRa” input node data to the
SD card and names the file evbCsv.

Hi Julien

In the screen shot you provided….
In Node Red, You could try and “enable” via WAN, then “submit”.
Also, under “Output Filter rules” enable “Allow Outbound” then submit.
Do a “Save & Restart” so the changes become active, then try again.

Hi Radim

The “ERROR” response to at+cpin? indicates that the SIM card is not detected
by the cellular radio. This would be the same behavior if the SIM card is
removed from the device altogether.

+CGREG: 0,0 response indicates the cellular radio is not “registered” on the
cellular network, and is not trying (indicative of the SIM not being detected).
+CSQ:24,1 response indicates a detected receive signal strength of 24 out of 31
If you are certain you have the correct size SIM properly oriented in the device, my only suggestion is to try another (2FF) SIM card and see if the cellular radio detects it.

-Best Regards

[Steve Kovarik]

Hi Julien

A couple of things to check.
In the AEP GUI “Administration” tab then “Access Configuration” there is a
setting for Node Red “via LAN” and “via WAN”.

Also look at “Firewall” tab then “Settings” for outbound filter rules.

[Steve Kovarik]

Hi Radim

What is the serial number of your Conduit?
+CMS ERROR 310 is an indication the SIM is not inserted. Can you please
describe the SIM card orientation in the SIM card slot.
http://www.multitech.net/developer/products/conduit/installing-conduit-sim-card/
Try using the radio-query utility to issue AT Commands directly to the cellular radio. http://www.multitech.net/developer/software/mlinux/using-mlinux/utilities/radio-cmd-usage/

Using the Radio-query utility issue the AT Commands below and post their response.
at+cpin?
at+cgreg?
at+csq
at+cmgf?
at+cops=? (wait 30 seconds for response)

Hi Szymon

Yes, that is normal. On power-up it can take up to 4-5 minutes before Node-Red is loaded and running. When used with LoRa, Node Red uses moderate processor resources. The latest Conduit firmware version 1.3.3 supports a new
feature that allows loading and running a custom application. This would
allow you to disable and not use Node Red, and create, load and run a custom
application that may accomplish the same. With Node Red disabled, you would
notice increased performance.

Hello Alejandro

The MultitConnect rCell 500 is a product designed to be sold and used in
Europe. At this time the rCell 500 does not have the necessary certifications
and approvals to be purchased and used in North America. If interested, you
would need to purchase through a distributor in Europe. Thank you for your
inquiry.

-Best Regards

[Steve Kovarik]

Hello Szymon

To determine if Node Red is running, you can check the process and view the log.

To do that SSH into the Conduit and issue the command ps -auxww | grep node

View the Node-Red log by going to var/log/app (then) cat node-red.log

Regarding range, Which advertised distances are you referring to?
I am assuming the Gateway and the endpoints have been configured for optimal
range. Maximum Transmit Power configured on Gateway and endpoints.
Maximum Spreading Factor (Data Rate) configured on endpoint for optimal
range.

Distance depends on conditions, configuration, antennas, desired throughput,
and usage frequency. In dense urban environments, a typical range is 1-2
miles. It is capable of 2-way single-duplex communication across distances
of up to 8 km line of sight, deep into buildings, or within noisy
environments.

With the Conduit indoors, centrally located on 2nd floor within a brick building
with the hinged, right angle antenna shipped from the factory, I achieve
connectivity anywhere inside our 175,000 sq ft facility, and about 300 meters
outside in our urban location.

In the same scenario with an antenna mounted on the roof of the 2-story
building we achieve 3km to 5km range depending on obstructions (leaves,trees
buildings, hills).

I have customer with an antenna on top a 6-story building successfully
covering an entire college campus.

I have another customer that achieves 13km line of sight, with the antenna
elevated at about 300 ft.

Multitech manufactures a MTDOT-BOX and MTDOT-EVB for the purpose range
testing. These devices have a program that can perform a 16 point site survey
cycling through a range of transmit power and spreading factors (Data rate).
These useful tools will store survey data in the device as well as send it
to the Conduit Gateway.

Hi Seamus

Thanks for the feedback.
You are correct, the Conduit can be configured as a packet forwarder or
as a private LoRaWAN network. I agree, the private option may be optimal
for production line testing. Model MTCDT-210A (AEP build) has a Node Red
development environment that may be easier to quickly achieve what you need.
Node Red supports Mosquitto and HTTP nodes as methods to forward packets to
your application server.

Connect Node-RED to Any Cloud Service’s REST API

Node Red provides a LoRa (out) node for the purpose of sending downlinks to
devices. At the bottom of the page at the link below, look at…
Transmit Packets From Conduit.

[Steve Kovarik]

Hi Seamus

Proprietary vendors?
You mean public LoRa Network Server vendors like Senet, Lariot, Actility,
Stream or “The Things Network”. In all these instances the Conduits
inherent “LoRa Network Server” is disabled, and the device is configured as
a simple “Packet Forwarder”.

As I mentioned, Multitech Conduits from the factory have an installed
LoRa Network Server for the purpose of supporting a private LoRaWAN deployment. Please see network architecture at the link below for a
description of Multitech’s out of the box private LoRaWAN ntwork.

Introduction to LoRa

Let me know any other questions you have.

[Steve Kovarik]

Hello Seamus

By default, Multitech’s Conduit Gateway with an 8-channel LoRa mCard
installed supports a private LoRa Network. Multitech manufactures two
versions of the Conduit Gateway that offers two development environments.
The mLinux version of the Conduit (MTCDT-210L) is an open source Linux
implementation.
The AEP version (MTCDT-210A) has the addition of IBM’s Node Red which is a
node.js javascript development environment and has graphical users interface.

You can find more detailed information on both versions at the links below.

Hi Szymon

We provide different build option of the Conduit Gateway,
some have an internal cellular modem capable of PPP for internet access
others do not have an internal cellular modem and only have an Ethernet
interface for access to the internet. If you provide the serial number off
the bottom of your unit, I can verify for you. Otherwise you can also tell
by the model number (on the bottom) and referencing the build options
listed on our website. http://www.multitech.com/brands/multiconnect-conduit

Hello Aitor

You would need to use a paperclip or something similar to depress and hold the reset button (micro switch) for 30+ seconds, until you see a change in LED status. When using a paperclip, you should be able feel the reset micro switch slightly depress, do you feel the micro switch slightly depress?
If monitoring debug, you would see the Operating System begin to reboot.

Hi Micheal

At this time, when using AT Commands it is not possible to read any of the
mDot I/O.

With AT Commands, there is the capability to send/receive data.
-Best Regards

[Steve Kovarik]

Hi Micheal

That may partly depend on which product you have and the intended application
for that device.

Do you have a device in mind regarding this question?

-Best Regards

[Steve Kovarik]

Also, at this time AT Commands do not allow reading any of the mDot I/O.
If you were using the mDot just to send/receive data, AT Commands would suffice.

-Best Regards

[Steve Kovarik]

Hi Michael

You could send the board back to the manufacturer for repair/replacement.
Open a support portal case provide the serial number and request a RMA.

Hello Albert

Are you confirming that this is working OK for you now and the problem has been solved? If so, what fixed it.

-Best Regards

[Steve Kovarik]

Hi Robin

Thank you for your feedback.
Yes, you do need a Developer Board.
Otherwise you’d need to develop your own that has the 40-pin receptacle to
plug-in the Dragonfly into.

In support of your project I would be willing to lend you one.
That is with the understanding you will ship it back to me at some time.
If interested, please contact me at SalesEngineers@multitech.com

-Best Regards

[Steve Kovarik]

Hi Robin

I’d like to know a little more please.
What project?
Which School?

-Best Regards

[Steve Kovarik]

Hi Fahad

At this point I would encourage you to register and open a support portal case at https://support.multitech.com/support/login.html

We can perform additional troubleshooting and the portal allows file sharing.

-Best Regards

[Steve Kovarik]

Hi Fahad

The modem should accept AT Comamnds with/or without a SIM card installed. I would recommend that you remove then reinstall the modem on the developer board. I’d recommend to secure the modem on the dev board with the 2 screws and try it again. The LED’s seem correct. Communicate with the modem using format 115200bps, 8, none, 1, CTS/RTS hardware flow control enabled. Use the DE9 serial cable provided with the Dev Kit if possible. Any SMA on the Dev board can be interfaced to the “M” main cellular antenna of the modem. I have been successful using a 4G SIM in our 3G modems, so it should work. Let us know how it goes.

-Best Regards

-Stevek

[Steve Kovarik]

Hello Fahad

Do you know what commands you issued the modem prior to it stop working? What LED’s are lit on the Developer Board. Regarding the antenna connector, use the “M” for Main antenna and use the “A” for auxiliary for 2nd diversity antenna if two antennas are used. The model MTSMC-H5-.R2 does not inherently support GPS, so there no GPS antenna connector.

[Steve Kovarik]

Hi Tibor

Please send me an email at skovarik@multitech.com to initiate communication
regarding SN#18356719

Thank You

[Steve Kovarik]

Hi Andy

I would recommend a low loss shielded RF coax cable, preferably a
240 series or 400 series.

What antenna do you intend to mount on the roof?

-Best Regards

[Steve Kovarik]

Hello Basha

You would need to interface an active GPS antenna to the “G” U.FL
interface on the modem, and place the GPS antenna where it has a clear
vies of the sky.

at$gpsnmun=1,1,0,0,0,0,0 (enable unsolicited messages)
at$gpsp=1 (start GPS receiver in standalone mode)

After a time, a continuous streaming of GGA sentences are sent to the modem
serial interface.

at$gpsnmum=0,1,0,0,0,0,0 (Stop streaming of GGA sentences)

at$gpsacp (get latest GPS coordinates)

at$gpsp=0 (Turn off GPS receiver)

Hi Tibor

Seems the device is non-functional and unrecoverable in the field.

That leaves us little choice but to ask that you send the device into
MultiTech for warrantee repair (or replacement).

If the device worked for you previously, could you provide more detail around
“appended two lines to /etc/network to start custom services”
