Can Contiki NG and Linux communicate via 6LoWPAN / IEEE 802.15.4?

I've just thrown this little page together…

I'll probably get rid of it once the backburning is passed, but this is the raw data along with the current conditions. The current conditions update each minute (self-refreshing).

I might see if I can get a chart going on it, the data's there.

Data flow is from the data logger → #6LoWPAN mesh → #CoAP proxy → #WideSky back-end → #pyhaystack → JSON files to be served up by #OpenHTTPD

The pyhaystack script runs from `cron`.

TIL about BeagleConnect™, which makes it possible for #mikroBUS based Click boards to be connected wirelessly (e.g. via #6LoWPAN over
802.15.4) to a #linux gateway.

A virtual bus is created on the Linux gateway (e.g. /dev/i2c3) that sends "bridged PHY" #greybus messages to the remote #IoT node. The remote node runs #zephyr firmware on an MCU that speaks the Greybus protocols and translates those messages into I2C, SPI, GPIO, etc on the Click sensor (no drivers on MCU!)
