Legacy RTCM3 messages

That’s great! I will do some testing tomorrow and will report back.
I want to ask if it is possible to have rtcm3 legacy and msm4 simultaneously.
For example the app doesn’t let you select 1004 and 1074 simultaneously but it lets you select 1004,1012 and 1094,1124.
Is it possible to work with 1004,1012,1094,1124 together? This could be useful if someone has the emlid base broadcasting to the emlid caster and 2 or more mixed rovers (legacy gps+glo and newer gps+glo+gal+bei). I am not requesting this feature. Just wondering if that works that way.
