BT747 - New code signatures

The code signing key used for BT747 had to be upgraded to SHA-256.

Unfortunately that also revoked the old key and apparently the timestamping was not properly done with the previous signatures.  So the java laucher complains that the certificate is revoked.

All files have been resigned and republished.

You may need to launch:

javaws -viewer

[on windows : "Windows Key + R" to access the execute popup where you can enter this].

bt747 mit anderer Software fernsteuern

Ich erstelle ein Programm (unter Win7, mit vb.net2010), mit dem ich mehrere Reisen verwalten kann. Die Tracks können mit Fotos versehen auf Knopfdruck in das Internet zusammen mit einer Fotogalerie und Erlebnisberichten gestellt werde.

Zum auslesen der GPS Daten (iBlue747) verwende ich bt747, dass bei Bedarf aus dem Programm heraus gestartet wird.
Das funktioniert auch hervorragend!


GPS Logger Device Compatibility

You can buy the iBlue 747 Pro logger on this site.

This is a list of GPS Logger Devices that BT747 supports. In general, BT747 supports devices with a MTK/MTK II-Chipset.
Support for other Chipset types/loggers is added bit by bit.
And even if your GPS is not a logger, BT747 may support GPS Chipset configuration.


Installing the Desktop Version of "MTK Data Logger Control BT747"

IMPORTANT: BT747 is updated with a CERTIFICATE to comply with JAVA 7 (1.7.0_51) security.
(I bought a trusted certificate (provided by a trusted authority) for about $300.  Received it on Jan. 17, 2014.
Thank you (!) to the users that donated a bit (thanks!) to partially cover the cost of the certificate.
 If every person using BT747 would donate $1 the cost would be covered in about two weeks (luckyly for you, I did not wait to cover the cost).
