Thingy:52 node.js/Raspberry Pi demos PDK support

dansam

I would like to setup the just released RasPI demo using the Nordic-Thingy52-Nodejs repo I don't have a dongle, but 4 PDK 52840 boards and 2 Thingys.

Can I still use 1 PDK attached to the Pi instead of a dongle?

    Hi,

    The Raspberry Pi has built-in Bluetooth. You don't need to connect a dongle or PDK to it. You can connect directly to the Thingy with Raspberry Pi.

    I am aware of that ... but ... it's not Bluetooth5 ... which is why we got the PDK boards

    What kind of Bluetooth 5 feature are you interested in?

    Take a look at the table on the buttom of this page for an overview over Bluetooth 5 support on the nRF52-series SoCs.

    Hii Sigurd, B5long range is our priority and , as soon as you release the Mesh SDK we want to have:

    • an app framework / setup that allows us to build networks using the 52840 boards
    • 1 PDK connected to a PI, acting as gateway to fixnet
    • 2 or more PDKs used as mesh hopping/routers nodes
    • a couple of thingys as leaf nodes sensing and sending data though the mesh

    given this setup using nordic products and that you have released this nodejs framework, my question is, can it work with BTooth5 (longrange) ?

    None of the nodejs supported devices (e.g. Raspberry PI) support BLE5 long range so the connection between the gateway and the PDK would be on regular BLE 1Mbps mode.

    Note that one of the benefits with mesh is that you actually don’t need BLE5 long range. More Bluetooth devices can be connected to a mesh network, and together they will extend the range of every node in the network. A mesh network will increase the range because A communicates with D via B and C, when a direct connection between A and D would otherwise be out of range.

    Regarding BLE Mesh that will be released: the official Bluetooth Mesh is based on the Bluetooth low energy part of the Bluetooth 4.0 Specification and shares the lowest layers with this protocol. I.e. the official BLE Mesh will not support BLE5 long range.

    If official BLE mesh is the best option for you depends on how many nodes and gateways you are planning to use. If you are planning only a few nodes a long range (BLE 5) solution with your own "mesh/tree" system may be the preferred option.

    Also note that we will release a production ready IoT SDK in Q3 this year. It will be built on SoftDevice S132 v5.
