I am using the autoupdate development version of bt747 (great software, thanks!) with my recently bought Holux M-1000C AXN_1.0-B_1.3_C01 (01029-00A)
I have the following problems:
(1) When downloading the binary log, Altitude and Speed get misreported. It seems that Altitude is reported as Speed (the values here make sense), not sure what happens to the real Speed (the table shows fractions in the range 1.234E-41 - 1.234E-43),
(2) After downloading the log a few times, the device became corrupted, i.e. bt747 was not able to download the log any more. Clearing the log with the vendor supplied software fixed the problem. I am unable to reproduce this issue.
(3) Erase log does not always work.
