New EspruinoHub hardware? Pi Zero W

Posted on
  • I just saw this announcement for the Raspberry Pi Zero W:

    raspberrypi.org/blog/raspber­ry-pi-zero-w-joins-family/

    $10, and has the same radio hardware as the Pi 3 (so WiFi and Bluetooth 4). It should be perfect as a device to run EspruinoHub on.

  • Or dare I say it, run espruino on it...

    A Linux build with wifi and Bluetooth....

  • Well, if you're up for writing a Linux version of the Bluetooth API ;)

    But yes, with the WiringPi Espruino build it's actually pretty snappy.

  • Perhaps - @JumJum and I will be looking at the Bluetooth on the esp32, the supplied libraries use bluedroid - I think this might be a higher level than the hardware driver?

    I think on the pi they use bluez- and from what I have read there is no Bluetooth LE support yet.

  • There is Bluetooth LE on Linux - but it's still not that stable and only works on new versions of Bluez. As far as I can tell it may be using DBUS to Bluez to do what needs doing... I don't think that's going to end up being portable to ESP32 :(

    It'd be nice to be able to make jswrap_bluetooth multiplatform though. I've tried a little, but there's still quite a lot of platform-specific stuff in there.
