in General Discussion
I got an email from Digikey regarding these Econais modules:

http://www.digikey.com/en/articles/techzone/2015/feb/next-generation-smart-miniature-wi-fi-modules-accelerate-iot-and-m2m
As the Internet of Everything begins to take hold, Wi-Fi is required to meet new challenges that are nearly as diverse as the applications it is finding in Smart Objects, the Internet of Things (IoT) and Machine-to-Machine (M2M) communications. While price continues to be a key driver for Wi-Fi solutions, they must now also deliver higher performance and lower power consumption while supporting a broader variety of specialized applications and higher-layer protocols

    Nah, the future of my IoT is LoRa not WIFI.

    Low power. Long range (up to 15Km). Low data rate but how fast does a "thing" need to report home?

    This is Symantec's detail info:

    Fake App Attack: Fake AV Website 5

    Severity: High
    This attack could pose a serious security threat. You should take immediate action to stop any damage or prevent further damage from happening.
    Description
    This signature detects a fake antivirus scan page that displays false virus scan results.
    Additional Information
    This signature is designed to prevent access to sites that redirect users or perform actions to trick users into calling the scammer and installing misleading applications such as fake antivirus software.

    The creators of misleading applications often use web pages with fake antivirus scanners in order to convince users to download and run an executable file. They may also use intermediate sites that redirect users from the site they are visiting to another one offering misleading applications for download.

    Misleading applications such as fake antivirus scanners (Trojan.FakeAV) or bogus disk defragmenters (UltraDefraggerFraud) are designed to mislead users into thinking that their computer has serious problems that must be fixed by paying for a license of the software. For example, a fake antivirus scanner may perform fake scans of the hard disk and then report multiple non-existent threats. To remove the threats, the misleading application tells the user to purchase a license for the software which may amount to anything from forty to one a hundred dollars plus, depending on whether a "support" package is purchased or not. Of course the software and any support packages offered are bogus and will offer no help whatsoever in cleaning up the problem or protecting against any other threats.

    Newer generations of misleading applications may also cause instability on the computer such as moving files around, hiding them, or preventing access to certain resources. This is done to coerce the user into buying the fake software.
    Affected
    Various operating systems

    I think you have fake antivirus software there Ron :)

    Would be nice if that report actually had some useful information in it. Said what the problem was. Like what file being downloaded is the issue.

    @Heater - did you see the mention of LoRa in the "ZERO GROWS A CAMERA CONNECTOR" post:

    "To celebrate our having designed the perfect high altitude ballooning (HAB) controller, Dave Akerman will be launching a Zero, a camera and the new GPS+RTTY+LoRa radio board that he designed with Anthony Stirk, from a field in the Welsh Marches later today"

    https://www.raspberrypi.org/blog/zero-grows-camera-connector/

    Edited to add:

    Then in the comments:

    "Where can I get a “GPS+RTTY+LoRa radio board”?"

    "Right now, you can’t, as it’s a new product and today was its first flight. Once we’re happy (and it worked perfectly today) production will start. It’ll be a few weeks before they’re on sale."
  • Heater.Heater. Posts: 21,230
    Indeed I did.

    I have been wanting to checkout the LoRa thing for about a year now. Ever since a friend of a friend showed us what his company had been getting up to with it.

    It's only recently LoRa boards have become available.

    LoRa looks cool, chips only from Semtech and seems more OSH and more data.

    Sigfox seems more professional, already available in SanFransico but is coming to 100 more U.S cities.

    But the 12 bytes per message/140 messages per day seems limited.

    tonyp12,
    ...chips only from Semtech...
    Not at all. Microchip have LoRa devices as well. Dev boards available "real soon now".

    Not sure how open or closed this is but I think the idea is that it's open...eventually...

    I have no idea what you mean by "more OSH and more data."

    Also where does that "12 bytes per message/140 messages per day" come from?

    As far as I can tell I can use cheap Lora modules to do whatever I like. Point to point with a range of up to 15Km. Many to point, with one point used as an internet gateway.

    The "ARM3 with built-in radio for $3:" for sure cannot do that.

    We shall see...

    LoRa and sigfox are not compatible with each other.
    LoRa, you seem to have to set up your own gateway in your city as no one in really in charge to do that, so that is more OSH.

    Sigfox business model is to be in charge of the gateway systems as IP is free to chip manufactures.

    Sigfox is the one with the 12bytes(timestamp and unit-id is also auto added) /140day limit as to comply with the European 1% radio duty.
    TI's $3 ARM3+radio cc1310 is sigfox certified.(TI's new Sub-1 GHz solution spans 20 km on a coin cell)

    As far as I can tell from Lora suppliers there is no need for a LoRa gateway. Cheap modules can communicate point to point, or whatever, without one. Of course you might want some node somewhere in your system to be accessible from the net.

    Your link is to some "SimpleLink" thing. It's hard to get Google to tell me anything about that. Except that it's some kind of WIFI. No mention of range to be found.

    It's not wifi (that would be CC3100)
    Point to point anyone can do, having a continent wide gateway system for roaming in place is a game changer.
    would be worldwide if it was not for the 868/902 licence debacle.

    Some tests have shown that Sub-1 GHz transmissions have an effective range up to more than 100 kilometer
    MCU can sense Sub-1 GHz signaling at –110 dBm at data rates of 50 kbps or,
    at an even slower speed of 0.625 kbps, down to –124 dBm.
    Interference from other wireless communications can be overcome with 90 dB of blocking
    and output power levels up to +14 dBm ensure robust signaling for longer range communications.

    "Network Operators".

    That there is what I want to get away from. That is the old model of cellular network providers and "cloud" service providers.

    I don't want to pay rent or be beholden to any such thing.

    I want to be able to have "my stuff" communicate to "my stuff". Perhaps ultimately through the internet by whatever means I like.

    For example: https://thethingsnetwork.org

    To develop and sell a successful Iot product, you would have to roll out your own city/country wide network operator in that case.

    There is nothing stopping the MCU from going back and forth between your priority system and sigfox gateway back bone,
    within reason of radio modulation and LoRa unfortunately is not.

    Say you want to be able to upload a need firmware by driving your car within 200ft of device, using some other higher baudrate p-p protocol,
    you should be able to do that.

    tonyp12,
    To develop and sell a successful Iot product, you would have to roll out your own city/country wide network operator in that case.
    Personally I don't want to do that. I have my things, and I have me, and I want us all to communicate. I don't want to be dependant on some third party.

    Professionally I can well imagine we would provide a service through gateways and such. Like we do already over wired internet or GSM or whatever.

    Sure a free crowdsourced wordwide sub-1ghz system set up that reach 90% of the population would be great,
    but selling 1000's of a product that relies on a "hippie culture" that is hardware incompatible with anything else when bottom drops out.

    sigfox fee for just one or two units is probably $5/year/unit?
    They say most modules you buy comes with one year free.

    For the big rollers the fee is $1/year/unit for 50K+

    Ha, never trust a hippie. To quote the Sex Pistols.

    Funny you should say that because the "internet" was started in the height of the hippie era, the 1960s.

    The whole idea was of a peer to peer network. A network of networks. With fault tolerance as a major priority.

    So, in my mind the "Internet of Things" should continue in that tradition.

    We already have examples, like Google's NEST or whatever, of things that become door stops because the service they depend on has gone away.

    Perhaps I'm prepared to pay 5 dollars a year for my IoT gadget to be usable from the net. However I don't want it tied to a single supplier. Let me shop around.

    As radio-mcu's like CC1310 that connects to sigfox uses IEEE 802.15.4g,
    with some different software settings/stack installed you can make it connect to who ever you want, so you should not be tied to single supplier.

    Sounds good.

    I have to look into this further.
