I have X-Plane 12.08rc3 with the RXP GTN 650 and GTN 750 installed. RXP GTN version 2.6.1.1 (update info shows 2.6.1.0 but I installed 2.6.1.1 ...). On RNAV approaches with vertical guidance (LPV, LNAV/VNAV etc) the aircraft HSI shows "NO GP" and vertical DI info is not shown. Problem demonstrated with the LR Baron 58 + GTN 750 and LR Cessna 172 G1000 + GTN 650. Laminar Research tells me the issue is 12.08 introduced a new dataref: sim/cockpit/radios/glideslope_signal_valid[4], which needs to be set to 1 for GPS approaches with vertical guidance. I verified this with a LUA script. I hope RXP can provide a fix in an upcoming release.

Thanks for the reply Jean-Luc. After further testing I concluded the 'RXP/radios/indicators/shared_touch/GTN_750_1' dataref only updates when I click on the touch screen area of the GTN display. The dataref change is correctly passed from Master to Slave. When I click on a bezel button like 'HOME', the dataref does not update. The result is an action on the Master GTN but none on the slave GTN; at that point they are out of sync. As a work around I started using a no-bezel popout and mapped the bezel button commands to the keyboard. These commands flow as expected between Master and Slave.

I received the following from Roman at SmartCopilot: If you issue the command by your LUA script, does it also gets transmitted to another pilot? If yes, you can attach these commands to X-Plane keyboard hotkeys and use it with keyboard only. HeinzXP note: I tried this and the HOME and DTO commands execute correctly on Master and Slave. It looks like these commands are working only in one direction: if the user issues the command, it will trigger the button event like in your example. It is also the main reason why the devs add these commands to control the plugin from external hardware. However, when the user triggers the button itself, the command is not being issued. You need to contact plugin developers and ask if they can make it work in both directions. It is minimal modification. Otherwise, there is no chance to capture the button events. Best regards, Roman.

Currently working to use SmartCopilot to synch RXP GTN 750s between Laminar C172s. I have included the following per previous entries above: [GTN_750_1] UseSharedTouch = true 2) configure SmartCopilot to share this dataref: RXP/radios/indicators/shared_touch/GTN_750_1=0 And also these commands: #REALITY XP GPS commands RXP/GTN/DTO_1 = 0 RXP/GTN/HOME_1 = 0 RXP/GTN/VOL_PUSH_1 = 0 RXP/GTN/VOL_CCW_1 = 0 RXP/GTN/VOL_CW_1 = 0 RXP/GTN/FMS_PUSH_1 = 0 RXP/GTN/FMS_OUTER_CCW_1 = 0 RXP/GTN/FMS_OUTER_CW_1 = 0 RXP/GTN/FMS_INNER_CCW_1 = 0 RXP/GTN/FMS_INNER_CW_1 = 0 RXP/GTN/CDI_SOURCE_1 = 0 RXP/GTN/OBS_MODE_1 = 0 RXP/GTN/TAWS_INHIBIT_1 = 0 RXP/GTN/MARK_ON_TARGET_1 = 0 RXP/GTN/TOGGLE_WINDOW_1 = 0 RXP/GPS/MASTER_DEVICE_0 = 0 RXP/GPS/MASTER_DEVICE_1 = 0 RXP/GPS/MASTER_DEVICE_2 = 0 Mouse clicks on the master GTN flow to the slave GTN but not consistently. For example, a click on the master GTN home button does not transfer to the slave. Any suggestions?
