Welcome to the ruuvitag_fw wiki!

These are the firmware projects currently available under ruuvi_examples:

ruuvi_examples

This includes the firmware which is installed at the factory. It samples the temperature/humidity/air-pressure sensor and accelerometer. It immediately transmits bluetooth packets. The format, frequency and contents of the packets depends on if it is in highres (aka raw) or URL mode.

In URL mode a web browser URL is transmitted which invokes a page at the domain ruu.vi. This page interprets the page fragment (Text following the '#') which contains encoded data and displays the temperature, humidity and air-pressure.

In raw mode packets are sent out which must be interpreted by one of several applications. One of which has been written to collect data in an Influx data base and presented by Grafana.
As of July 2018 (and the foreseeable future) format 03 is transmitted by the firmware loaded at the factory.
Other formats are available by installing alternate firmware.

As of July 2018, there is no "well known" firmware which collects data and periodically (or on command) dumps the data.
