Time mark missing / Raspberry hot shoe

Hi all,

I have some troubles with the time marks.

Firstly, I used the 2.5.0 firmware version, and used the RTKLIB b27, and I performed a time mark with a raspberry (the GPIO is set high at the begining of the script, and go down during 40ms at each acquisition).

I see some points are missing in my event file (find in the link the UBX file, I used GPS, GLO, GAL and a base with a coordinate manually defined).


I do not know if there is a bug to my side or in the RTKlibā€¦
40ms signal for the time mark is enough long ?
