Hi Andrew,
We ordered Metahub and MMRs. Now I am not able to see display of Raberry Pi login screen – HDMI connection with Metahub – FRESH – NEW AND FIRST TIME POWERING ON METAHUB.
1. 7inch Display connected – (tested with laptop connected screen – working ok)
2. HDMI cable connected -(tested with laptop connected screen – working ok)
When power on Metahub – FRESH – NEW AND FIRST TIME POWERING ON METAHUB. – LED light RED is ON
3. Connected Display screen – “NO SIGNAL” – Message on screen. Looks Blue and blank screen – No LOGIN Screen
Please let us know how to fix, or replace the MetaHUB.

    It's a raspberry pi so you shouldn't have any trouble booting it. Just follow the steps here: https://www.raspberrypi.org/help/quick-start-guide/2/
    Please note that the SD card is already provided and comes with Raspbian + MetaWear pre-installed. You just have to plug in the screen, mouse, and keyboard (and then connect to the internet).

    Is that a question or a confirmation?

    Try connecting the hub to a different monitor.

    1. Yes, I followed all your the online help from Raspberry and mbientlab - tutorials and read related forum query from discussion.
    2. Hub connected to diff. monitor still no response on screen - no signal.
    3. Can you send me link MetaWear pre-installed and copy in new SD Card? Where I can download MetaWear pre-installed files? So I can try installing in other raspberry Pi module that is ordered from online market.
  • I connected new Raspberry Pi module and inserted Metawear loaded SD card from METAHUB.
    Its working - Fine. able to run metawear app in Raspberry.
