Postcard RTK: Base Mode Frozen v2.3 02/10 and v6 LG290p  
Hey everyone, I’m just bothering you.  
With version 2.3 of 02/10 and v6 of the LG290p, Rover Mode started again without problems, but now it’s Base Mode that tries to start, and it freezes with the word BASE on the port shield screen.  
Regards

Hi Angel (@amlago ),

I am starting to investigate this. My notes are in the GitHub issue below.

Best wishes,  
Paul

Hi Paul @PaulZC ,reading #747 , on mine (not postcard) the default on v6 is for all 3 e.g. $PQTMCFGPROT,R,1,3\*3F $PQTMCFGPROT,OK,1,3,00000007,00000007\*69

as (per undocumented) bit 0,1,2 and the …00000000,00000000\* close the port.

Hi Paul @PaulZC ,(edited) the elevation masks for RTCM & NMEA are independent and are compatible with each other.

PQTMCFGRTCM

and PQTMCFGELETHD

they work separately on the same configuration at the same time

Thank you Marco (@bamarcant ),

The firmware already passes the `settings.minElev` value to the LG290P through the PQTMCFGELETHD command. `settings.minElev` defaults to 10 degrees; the user can change it through the menus or web config.

Do you think we should:

- Pass the same `settings.minElev` to PQTMCFGRTCM?
- Create a new, separate setting for the PQTMCFGRTCM elevation?
- Leave the PQTMCFGRTCM elevation set to -90 (as it is now)?

Thanks again,  
Paul

`minElev settings are two, one for `RTCM e.g. $PQTMCFGRTCM,W,7,0,55,07,06,2,1\*00

and other for NMEA output e.g. $PQTMCFGELETHD,W,45\*18 at the some time for the same setting:

I leaved the default rover\_mode and changed alternatively the PQTMCFGRTCM and the PQTMCFGELETHD; being in rover mode I enabled also all the rtcm’s then I could see them (rtcm) in rtklib on one panel and the nmeas (GSV) on another panel at the some time with the same but distinct configuration for both rtcm and nmea…

Imho better two separate settings because PQTMCFGRTCM affect only rtcm and PQTMCFGELETHD affect only nmea sentences; if possible also a setting for PQTMCFGCNRTHD.
