Dynon AP controlled by Ipad with Skydemon

[Taigajoe]

Hello,


I connected my Ipad with Skydemon via bluetooth to serial adapter to my HDX800.
It works well - the AP is following the route which I planned on Ipad.
So far so good.

In the configuration of Skydemon you can select about 9 different NMEA sentences.
I selected all of them.
But I would like to reduce them to an minimum.

Does anyone know which NMEA sentences are necessary to control the AP?

Of course I can reduce the selected sentences step by step...

Thank you!

Hi Trevor,
Please can you share what settings you used for the serial in device and serial function on SkyDemon.

Thank you!

I used "Garmin 296" with 9600 Baud. The Irxon BT578 V3 adapter is preconfigured to 9600 Baud.

I presume you have SV servos so SV is driving the autopilot with Skydemon as a Nav source to SV. Is this correct and can the BT adapter just use one of the harness serial connections ie no need for an ARINC?

Yes, this is correct. Skydemon works as a Nav source to SV. One BT adapter works only with one serial port.

Hi,

Are you able to show the wiring connections you made please? Was it from the BT578 to the servos or the HDX? Some more detail would be appreciated.

I have asked Skydemon if they are able to send vertical nav data to the servos. The setup they have now doesn't do that but they have added it as a request.

Perhaps if others here sent a request for them to add that feature they might prioritise that feature. It would then negate the need for Dynon to provide vertical nav as they have ditched their development of that last year.

Regards,
Trevor

What vertical nav data will be sent from SlyDemon? There’s no approach information as it’s a navigation app, not an FMC.

Can you expand on the SV config? I currently have an old Garmin 495 connected and can use and depict on the HSI but it doesn't show as a nav source so won't drive the A/P. Hence I wondered if there was some additional config I'm missing before I purchase and hookup a BT adapter? My SV is Classic, not HDX, but I wouldn't have thought any different in this area (unless someone knows different....)

Skyboy, this thread is aimed at the SkyDemon app and the recent additional capability to send the nav data, via Bluetooth, to a receiver which then sends serial signals to the SkyView/HDX to give lateral guidance straight from the SkyDemon app, without having to first transfer a route and then use the NAV function. The mention of Garmin 296 was only for the serial input selected by Taigajoe.

I have no idea if the Garmin 495 will transmit the nav data over Bluetooth but I suggest a different thread is started so the conversation about SkyDemon doesn't get derailed. SkyDemon have specifically added extra options to enable the data to be sent via Bluetooth and a similar sort of thing would need to be available on the 495 for it to act as a nav source and be recognised as such. I don't think it's necessarily an input config problem but more of an output problem.

 

[skyboy999]

Think you misunderstand me Paul. I fully understand thread is about Skydemon and that's what I'm discussing. I'm not trying to drive a/p with G495 (and certainly not by BT!)- the point I made was that I have previously tried the G495 (via hardwired serial) and couldn't drive a/p because it wasn't recognised as a Nav Src (*though it would depict bearing bug on the SV HSI).

What I want to do is to drive the (Skyview Classic/SV Servos) from Skydemon. Key to this (as I understand) is that the input stream (from iPad/Skydemon/BT adapter) is recognised as a Nav Source and I thought that required an ARINC in the setup which I don't have. Hence trying to clarify setup in SV.

Evidently, I didn't get that across in my post. Hopefully this will clarify and someone can confirm feasible with my setup and how to config.

 

[PaulSS]

Ahhh, all understood. Taigajoe did reply to you and said that SkyDemon does work as the nav source and, with the BT adapter wired to a Dynon serial port, there is no need for ARINC.

Have got SD working as an HSI source for the AP but did anyone manage to connect up the (or a second) BT dongle to send radio frequencies from Sky Demon to the Skyview integrated radio (SV-COM-X83) ? We're not able to do it with a serial input or by connecting direct to the radio. If anyone has solved this would be grateful for a steer.

 

[skyboy999]

Now set up and SD/iPad recognised by Skyview as an HSI source (and shows bearing and distance). However, the ‘HSI+ALT’ option is greyed out so cannot drive the A/P. Am I missing something or does functionality not work on Classic ? Grateful for any pointers.
