There is a new Raspberry Pi 3 coming with WIFI and BTLE.

I know it's poor form to advertise other guys products here buy hey my Propeller Pi can go wireless soon.

Official FCC test reports here: https://fccid.io/2ABCB-RPI32
and here: https://apps.fcc.gov/oetcf/eas/reports/ViewExhibitReport.cfm?mode=Exhibits&calledFromFrame=N&application_id=Ti/YleaJNSl+TR5mL5C0WQ==&fcc_id=2ABCB-RPI32

Leaked story here: http://www.theregister.co.uk/2016/02/26/raspberry_pi_3/

The forum mods over at the Pi Foundation are having a busy morning deleting all the posts mentioning it as people spot it every few minutes.

    re: Raspberry Pi 3 with WIFI and BTLE coming soon

    I was surprise when I read the new's today . I'm just getting used to the Pi 2. :)

    Sounds like they are getting into the Internet Of Things market .

    I'm not sure IoT is necessarily an aim here.

    WIFI and Bluetooth have been oft' requested features in the Pi world. If they can add it cheaply then why not? Especially for a Pi birthday announcement.

    I don't really think of the Pi as an IoT device. Too big, to power hungry. As an Iot gateway perhaps.

    It's funny, people who discover this are posting all the time, all their posts get deleted within minutes. The Pi Foundation really does not want to discuss this before any announcement. Understandable I guess.

    It's gone up to 64-bit quad-core @ 1.2GHz.

    Thus even more powerful!

    (We've got to do something while waiting for the new Propeller!)

  • Heater.Heater. Posts: 21,230
    Wait a minute. Where did the 64 bit thing come from?

    I'd bet on it being a Pi 2 with a one or two extra WIFI/BTLE chips added. Looking at the photo's I only see one new little package on the board.

    The processor looks the same as the BCM2836 quad core Cortex A7 SoC found on model 2 B, but one redditer claims it could be a 64-bit processor due to some MagPi ad. [Update: that’s the MagPi ad which confirms Raspberry Pi 3 will feature a 64-bit ARM processor @ 1.2 GHz. Thanks Gabe!

    Oooo...I love a lot of speculation ahead of announcements.

    Mean while my Raspi 2 is WIFI connected and programming Propellers. Life is good.
  • Heater.Heater. Posts: 21,230
    Looking at those pics I don't see anything that looks like a WIFI/Bluetooth antenna. Unless its that white thing that looks like a connector they have circled in red.

    But then I wonder why it is so far away from the new chip, also circled in red and presumably the WIFI/Bluetooth chip.

    I like the way they say "So the only major changes on Raspberry Pi 3 appears to be built-in WiFi and Bluetooth, and 64-bit ARM cores". As if a change from 32 to 64 bit was nothing much.

    All in all I'm not convinced about the 64 bit thing yet.

    There is a chip antenna on top left, in board's upside down pic you can see the ground plane keep out. (upper right)

    You mean this upside down pic:

    http://www.cnx-software.com/wp-content/uploads/2016/02/Raspberry-Pi_3_vs_Raspberry-Pi_2_WiFi_Module.jpg

    I see a chip, and a connectory looking thing. I don't see anything that looks like an antenna, like those funky PCB traces you see on ESP whatever boards or some ceramic do dad.

    The red circle is blutooth/wifi coexistence RF switch, to the right of it you see that the pcb is lighter green = ground plane keep out.
    on the top pic you then see the white/beige chip antenna all the way at the edge of the pcb.

    Switching the layer of 50ohm antenna feed is not recommended, but I guess they know what they are doing

  • Heater.Heater. Posts: 21,230
    OK. I was guessing the white/beige thing was an antenna. It just seems to be far away from the chip. But what do I know.

    No, the white thing (at the lower edge and not fitted on version 2) is a socket (JTAG according to another article) for mylar strip connection - you push the mylar strip (with goldfingers) into the connector and then push the white edge piece to clamp the pins.

    There is a white long thin rectangle circled in orange on the other post. This is on the reverse side on the edge where there is no copper. Its like one used on some of the ESP8266 boards instead of the square wave style pcb antenna.

    WiFi has been a missing part of the Rasberry Pi since its original release. BLE is a bonus too.

    How are your current Pi work wirelessly with the Prop?
  • Heater.Heater. Posts: 21,230
    Clusso,
    There is a white long thin rectangle circled in orange on the other post.
    I'm not seeing this. Where are you looking?

    I'm wondering why there might be JTAG socket on there . Surely JTAG for testing gets by with some test points normally?

    Certainly WIFI has been missing. But considering cost constraints hardly surprising. Prior to the launch of the Raspi one of the best ARM boards I could find was the IGEP board from ISEE. https://www.isee.biz/products/igep-processor-boards/igepv2-dm3730

    WIFI and all, but nearly 200 euro a board!

    Bob,

    What is EUT?

    I get: "You are not authorized to access this page."
  • tonyp12tonyp12 Posts: 1,951
    This is the 2.4GHz chip antenna, as there is no ground plane underneath it.

    re:What is EUT?

    I don't know but would guess that it's a FCC term meaning something such as the Electronic Unit Testing Or Electronic Unit under test, Equipment Under Test. I downloaded the doc(PDF

    In the pic(video) three posts above, on the lower edge about 2/3 across to the right, there is a white connector. This is not fitted on the B2. There is an article that calls this the JTAG connection and the connector is probably not on the final pcb.
    In the post above that (tonyp12) the aerial chip is circled.

    It's no surprise that wifi and BLE haven't been included. It has been too expensive. But its great now. I don't even have an Ethernet network, and haven't for many years - Wifi suits me fine ;)

    Wifi is certainly casual use convenient, but the Up Time of WiFi here is not great, on the multiple units that use it.

    jmg,

    What's up with your WIFI up time?

    My two Pi, (2 and B+) have been using only WIFI connections for ages, I have not seen any WIFI up time problems.

    Here:

    and here:
    https://87.100.174.67

    I did have reliability problems with WIFI on my early Pi, but so much has changed since then, the Pi, the OS, the WIFI dongles, the PSUs.

    Mostly WiFi here links a HP Stream Tablet, and a Samsung laptop, both running windows 8.1 & sundry Apple phones. (the Apple seems more reliable)

    Windows Sleep modes especially seem to mess with the WiFi, and sometimes a total reboot is needed to get 'everything back on the same page'.

    Not sure I'd want anything like industrial control relying on WiFi.
    (well, or windows 8,1 ... )

    Well, hate to break it to you, but not only is WiFi used in industrial remote-control cranes and warehouse autonomous robots, but there is also machine safety over Profinet protocol called PROFIsafe that can run over wireless. Crazy? Yes. But not something a hobbyist is likely to touch using a raspi and $5 USB to wifi adapters with dodgy drivers.

    And yes Windows is used on factory floors, usually for visualization and display. It's better to not try to re-invent the wheel for keyboards, mice, memory sticks, printer drivers, LCD monitors, and everything else. Where windows is used in control applications, RTX (real-time extensions) are used. Like anything else in this arena, proper testing and certification is certainly a big factor.

    No problems here with various Windows laptops. I only have a WiFi connection to hotspots by either my iPhone or iPad to internet over cellular. Been doing it for years. I don't have a landline (and certainly no landline when we were on our boat!)

    Hmmm...How is there anything "dodgy" about the WIFI drivers in the Raspbian OS used on the Pi? Dodgy WIFI drivers is the realm of Windows and it's infamous FTDI malware updates.

    Pretty much everything here at home and at the office is WIFI connected. The most unreliable part is the WIFI router's connection to the internet. Keeps loosing DHCP for some reason. Not sure if that is my router of the ISP though.

    @Heater: I applaud you for standing up for RPi and Raspbian. At such a diminutive price, one might well expect dodgy behavior from time to time. But I've never used a more robust and expansive system in my life. It never ceases to amaze me how much expertise and heart have gone, and continue to go into RPi development. It's a level of attention that money couldn't buy.

    I've just ordered two of the new RPi 3s from RS. They have plenty in stock, but I expect that they will go quite quickly. Should get them tomorrow.
  • Heater.Heater. Posts: 21,230
    Whoa, the new Pi really has moved to 64 bits. And 1.2GHz. Incredible. I really did not think that would happen so soon.
