New BLM Version 3.0.265

BLM IconI finally found time to publish the new BLM version. I decided to make it a new major version (3.0.265).

Aside of a face lift and introduced version check at startup, this version contains a feature to detect the take-off and landing positions. While we have intensively tested the feature during the last big competitions (Europeans 2015 and WAG Dubai), please use the detected positions with reasonable care.
The algorithm to detect take-off and landing is based on some work from Flytec and uses the barometric altitude, variometer and GPS ground speed.
Please note that sometimes multiple take-offs and landings could be detected. (in low wind conditions or if the balloon is moved)

You can download the new version from the BLM page.

New major release: Firmware 1.3.240 and BLM 2.2.240

I’ve just released a major version for the logger firmware (version 1.3) and BLM (version 2.2). This firmware introduces several new functions:
– The logger records variometer information
– The logger has a new “Navigation” screen which shows ground speed, heading and variometer.
– A new user.cfg configuration file allows user specific configuration which doesn’t affect event configuration.
– Declarations can now also be in 5/4 format. This format must be activated by configuration.
– Improved GPS detection and support for latest Flytec hardware
– Support for Bluetooth (Only available for private owned loggers with Bluetooth modules).
– Shows SBAS/WAAS status and records the status to the IGC file
– Improved precision of stored GPS position

Important: This new firmware changes the IGC file format. The new format is currently supported by eKLIPS, Boxy, BScoring. I don’t know about the other software. Check a recorded track before the first competition flight and update scoring software or downgrade logger if needed. I will keep the 1.2.x firmware online.

Also the SignatureLib was updated, because the signature key of the IGC files are changed to improve security.

You can download BLM and Firmware from the corresponding pages.

New BLM 2.1.189

Added new feature:
– Display and export to excel of the position where a declaration was made

Fixed issues:
– Export also points with no GPS fix to BFA scoring text file
– Fixed issue with regional setting dependency of BFA scoring text export

The software can be downloaded on the BLM page.

New BLM 2.1.187 / updated SignatureLib

Added new BLM with the following new features:
– Added Swedish Grid SWEREF 99 TM. (no firmware upgrade of loggers needed)
– Added Drag&Drop for opening files.
Fixes:
– Fixed issue for signature validation when IGC file contains non-ASCII characters.

Also SignatureVerifier and SignatureLib have been updated to fix the bug mentioned above (for developers only).

The software and firmware can be downloaded in the Official’s section

New Firmware 1.2.180 and BLM 2.1.182

Added new firmware (and BLM) with the following new features:
– Depending on setting by the event director disallow multiple marker drops of the same number during flight.
– On startup in case old goal declarations or marker drops are found, ask the pilot if it is a new flight.
– If the logger is set to use GPS altitude, don’t ask QNH.
The software and firmware can be downloaded in the Official’s section

New Firmware 1.2.172 and BLM 2.1.174

I just published the latest Firmware and BLM software. It is almost one year since the last official release, but we did a lot of work since… I just didn’t find time to publish the latest versions.
The big improvement is the introduced flexibility in coordinate transformation. We can now support use many map datums and grid systems. But also BLM has completely been redesigned and improved.

BLM 2.1.174
BLM is completely rewritten and also renamed to just BLM! It is now even much stronger, supports the same coordinate systems as the logger and can export data to WPT, PLT, GPX and Excel. See a full description at its separate page.

Firmware 1.2.172
New major firmware version 1.2:
– Added map datum and grid system support. Datum Support is dependant on the BLM software version. The following Grid Systems are supported:: Lat/Long, UTM, Custom Transverse Mercator, British National Grid, Swiss Grid
– Improved battery handling
– Use RTC to have correct date/time before GPS fix

It also contains the following fixes:
– Fixed minor issue with rounding of instrument error
– Fix problem with wrong date being shown as the first fix date at some conditions
– Fixed communication for flash dump
– Added hardware support for the latest hardware generation (2011 built devices)
