I have a client who wants a solution to allow delivery people to text (SMS messaging) in that they have completed a pick up at a particular location. What I'm looking for is Code to read an imbound SMS message or a SMS component if appropiate. This would allow me to create a windows service to read the message and update a SQL record accordingly.
Probably not quite what you're looking for but one approach is to use a gateway like iTagg which provides a number of interfaces for developers to send and receive SMS/MMS etc. Depending on your location, iTagg may be no use but I'm sure there'll be an equivalent for your region.
Sometime ago I implemented something similar using a GSM modem. I think most of the GSM modems offer AT commands that can be used for receiving and sending SMS messages. At the time, I used a library in Java that provided a easy to use API. The commands to read and send SMS are really easy but I bet there is something in .Net for that purpose that can make the task even easier.
I made a little search and I found this article with an example of using AT commands to interact with a GSM phone. I looked into the supplied source and it includes a library with operations related to SMS.
In my previous project I used a Siemens GSM modem with a RS232 interface. It wasn't very expensive and was able to manage all the messages sent by onboard units placed in vehicles. But if you have a unused phone it can work as well.
Thanks Luke, I am thinking more of a GSM modem which would be connected to the server. I think this would give more control rather than go through a third party, but I take your point and will investigate further.

I have a Google Home Mini and I'm trying to use it as a speech-to-text device. The way I intend to do so is by having the device listening to what is said and publishing that input to an MQTT broker in order to my application to listen to it.
I have found this, that returns the input as text, but all it gives me is the certainty I can get this data. I have little to no clue on how to make it publish this data as an MQTT message.
Also found this, but can't make it work, because it states "There’s a very easy way to recognize custom phrases in Google Assistant,[...] I won’t cover it here". And even the Google's instructions (open "Create an Applet") seems to be out-dated in relation to IFTTT, because the steps simply aren't followable in IFTTT's interface.
Here is a quick sketch of the architecture:
There're 5 arrows. The first one is, obviously, a physical process. Arrows "Audio" and "Text" are automatically done by the hardware. The right "MQTT Message" is working already. So what I wanted help with is the "MQTT Message" arrow from "Google Home" to "MQTT Broker".
Thanks in advance.
The short answer to this is you don't (as you've described it).
The slightly longer answer is that you first have to move the arrow you are interested into to the cloud and it's not a MQTT message.
The Action box needs to be hosted on a publicly accessable machine (e.g. AWS/GCP/Azure/IBM Cloud) so that the Google platform knows where to find it.
Google have 2 different types of actions, one for conversational type interactions and one for controlling smart homes devices. You've not mentioned what you are trying to do so I can't say which one you really want.
Google have recently announced the Local SDK for interacting with smart home devices that is slightly closer to the diagram you have included. This can only be used for device control and still can't send MQTT messages, it supports HTTP, raw UDP or TCP (you might be able to implement a MQTT client using the raw TCP, but it would be a lot of work and I'm not convinced the keep alive would work)
I think I got what you need:
Configure the Google assistant to parse your speech, then connect it to ifttt (as I already did it in the past, it's very easy) to send HTTP requests.
NOW create a local web server that understands these requests from ifttt, and publish them to your broker.
And that's all!
By default gammu have support for most standard modem. I have a very particular modem with some special requirements and I would like to add a protocol to gammu.
Is there a guide for this somewhere or someone who can list the basic steps for me?
EDIT: #user1664784 recommended to look att Kannel, and actually any system able to handle incoming and outgoing SMS is acceptable as long as it is stable. But I need to know how to modify the system so that I can handle a specific protocol. It is AT-based but a slight dialect. So any suggestion of a system handling SMS from a device connected over serial port is interesting. I need to find a system where someone can give me information on where in the source code I can begin adding a new AT-based protocol.
If someone have done some sample code in this area it would also be greatly appreciated.
It really depends how much different it is from standard AT commands.
If the difference is minor (eg. needs custom initialization), it can be easily achieved by feature flags. This can be seein ATGEN_PostConnect which handles initialization for ZTE or Huawei devices.
If the differences are big, you will probably need to write own driver, which will fall back to AT in some cases. Something similar can be seen in the AT OBEX driver which switches Bluetooth connection between OBEX and IrMC modes.
I think we used to have documentation on adding support for new devices, but I'm unable to find it right now.
Can i have two clients use DJI onboard SDK to talk with the craft?
For example, one to read the flight data, and another to set command to craft.
Not officially supported.
You could engineer a solution that involves your 'read' client merely sniffing the UART line for broadcast data, and your 'write' client implementing a full bidirectional communication. You do not need to obtain control of the aircraft to receive broadcast data, so this solution could work.
Bear in mind though that adding a fragile sniffing solution will give you low robustness and should be used with extreme caution on a flying robot.
I've encountered a choice I have to make.
Please advise what is the best choice for SMS platform between Kannel and Jasmin SMS. Who knows any pros and cons?
As a python programmer I feel more comfortable with Jasmin. It works very well, and the main advantage to me is that I can customize anything I need.
My experience with Jasmin is great, and I currently use it to connect to 4 SMSC and load balance between them. I have sent millions of messages without any performance problems at all.
My experience tells me that every SMSC has specific needs, and with Jasmin I can go into the code and change what I need.
This code is well written !
Both systems are very versatile and can be configured to perform complex tasks.
2 main difference that i find :
SMPP: Kannel implements only smpp client functionality and cannot act as SMPP server , while JasminSMS implements both.
MODEM: Modem interaction is very flexible using Kannel. I think its not available in the JasminSMS, but can be added using a plugin (https://github.com/jookies/jasmin/issues/697)
Could you give some examples of zeromq?
Let's say you want to have a bulletin board of some kind. You want to allow only some people to see it, by subscribing to the bulleting board.
This can be done using the publisher/subscriber model of ZeroMQ.
Now, let's say you need to send some asynchronous messages. That is, when a message is sent from system A and needs to get to system B, it is guaranteed to be delivered later, even if systems A and B cannot communicate at the moment when that message is sent. You can imagine a use case being SMS messages.
This can be done using asynchronous messaging model of ZeroMQ.
Basically, any JMS compliant solution like ZeroMQ will allow you to reliably broadcast or send a "message", whatever that message may be, to some other party with as little hassle as possible.
Please see the ZeroMQ blog -- they regularly post usage stories about different deployments, language bindings, etc.
IPython uses ZeroMQ for parallel computing features, the qt console and the notebook.

My personal use of this library is cross language communication:
I pass data between Python and Haskell
