LDS02 by Dragino - rx2 5sec problem in v3

Does anybody know, if the download problem in v3 now has been solved by dragino in current firmware used in LDS02 door sensor?

Problem was the 5 sec rx window in LDS01.

Or did they just replace battery holder (2*AAA)?

Given the date of the firmware downloads available on the website it will require the same work around the LDS01 requires.
