Hi, I started this topic here because it is connected to both products.

I'm the developer of the Carenado C152 Unofficial update.
A while ago I added RXP GTN650 as a new device. But now I'm just about adding a GNS 430 too (only RXP not X-plane default), see sample screenshots here.

All the different layouts are configurable by a plugin system, so either GNS530 (X-plane default GPS), GNS430 (RXP) or GTN650 (RXP) can be selected as active layout, in any case the GPS should be the unit1.
Since only one RXP device can be Master as unit1, I'd like to ask the developers if it would be possible to add a dataref or command based feature to let external plugins enable or disable a RealityXP GPS, or set it as Master. 

Thank you in advance,

BR Adrian

 

Hi,

It is all pretty much detailed in both User's Manual:

• You can detect which unit a user selects from the RXP menu ("gps_unit") and then show/hide your geometry based on this.
• You can also change the master device with dedicated commands ("RXP/GPS/MASTER_DEVICE_#") or in directly writing the encoded 'gps unit' number (or 0) in the 'master device' dataref (undocumented but you'll spot this one easily).

We've also adopted similar dataref naming conventions and capabilities between the GTN and the GNS V2 in order to facilitate such integrations too.

Thank you for your reply.

But in fact I'd do the opposite. I'd change layout with my plugin (setup sheet with tons of other configurable features) and I'd ask RealityXP to follow the changes. 

I did read the manual many times but I couldn't figure out if there is a dataref that shows which unit is the MASTER at the moment. I already figured out gtn_unit and gns_unit datarefs but they didn't change wether actual unit is Master or not. If there would be a dataref that shows which is the Master than I could use the dedicated command ("RXP/GPS/MASTER_DEVICE_#") to switch master device. 

Thank you in advance,

Hi,

I'm sending you a PM for some details.

As for 'the other way around', it is not possible at this time and most likely won't be in a near future, because of the limitations of the XPlane SDK and the capabilities offered to manage our 'gauges' in the simulator.

Nevertheless, I think it is better to let the customer choose its RXP devices at will, and have the aircraft self-adapt dynamically. Our published datarefs make it very easy and the modeling SDK allows you to show/hide geometry conditionally.
