Gecko Firmware Updated

Gecko firmware version 3.1 is now available for download. Featuring faster access to data with more “right arrow” information lines and more “up arrow” realtime data pages, this version of firmware also supports the 4th channel available on new Gecko Compact and Rugged recorders. Other changes include simpler sensor selection, vector peak Level triggering, and improvements to our implementation of MiniSEED data format.

The upgrade process is as simple as ever – download the Rasbora.bin upgrade file, copy it onto your Gecko’s SD card, insert the SD into your Gecko and then apply power. If you are upgrading from v2.9 or later, the Gecko will retain the current settings, but for older versions it will use settings file on the SD card to apply your settings to the Gecko after the upgrade. The whole upgrade process only takes about 10 seconds.

To complement the new Gecko firmware, our free waveform analysis software has also been updated with a new component rotation feature and the ability to customise the magnitude estimation formula. Download the latest version of Waves here.

Firmware v2.9 brought improved reliability to remote firmware uploads, addressed a bug where the “Stop Sampling” function had no effect, and fixed incorrect channel labelling in Histogram and Trigger log files. Version 2.8 was a major under-the-hood tune-up of the firmware that addresses a number of bugs and improves telemetry efficiency and MiniSEED data compatibility.

Version 2.5 brought improved reliability for the optional Telit 3G modem, while v2.4 introduced many new features discussed below, support for remote firmware upgrades, remote Gecko configuration via the Live Stream app and eqServer, performance improvements and bug fixes.

The Histogram feature creates a daily CSV file on the SD card, with data logged every minute. The file can be easily imported into Excel or other graphing packages. The CSV file stores the maximum and minimum signal values for each channel from the previous minute, the supply voltage, internal temperature, latitude, longitude, altitude, horizontal and vertical GPS accuracy, and the clock crystal information.

By plotting the peak signal values you can quickly visualise a day of monitoring activity, which is particularly useful for blast monitoring applications.

When a Gecko is connected to a computer running Kelunji Hub (included in the free Windows/Linux Live Stream app and on eqServer) via Ethernet connection or cellular modem, in addition to continuous data streaming we now have a “Triggered Only” mode that just sends instantaneous trigger packets, suited to EEW (earthquake early warning) applications. Kelunji Hub can immediately generate an alarm, then request waveform data from the trigger time from all connected Gecko recorders for further analysis.

You can now also save your Gecko configuration file and then load that configuration file into another Gecko, which is particularly useful when pre-configuring large numbers of identical instruments for a deployment. Don’t forget to change each station code!
