I'm going to say one last thing about this then I'm going to shut up as a) I've been ignored every other time I've posted about it and b) I'll be using the Global Caché IP2IR as soon as I get it so hopefully I'll be shot of the Harmony hub and won't care any more (apart from feeling sorry for other people still using it).
I've been poking around looking at how myServer communicates with the Harmony hub and how it asks it to send IR commands. It looks to me like myServer uses the open source Harmony library from
here
. It also looks to me like myServer uses the client.SendCommandAsync() method to send IR requests to the hub. This only sends a 'press' command to the hub, it never sends a 'release'. The Harmony library has a test harness program that you can run to try things out and it too uses SendCommandAsysnc() to send requests to the main library. And when I use that test harness to send navigation commands I get exactly the same thing as with myServer - one navigation command results in the cursor, highlight or whatever moving two, three, four or more spots in a list on the device. I've tried this both with Kodi and my Sky+HD satellite box.
I then edited the test harness code and made it use the client.SendKeyPressAsync method instead of SendCommandAsync. SendKeyPressAsync is coded to explicitly send a 'press' request followed by a 'release' request. Making this change fixed the problem both for Kodi and the Sky box and navigation worked as desired - one command results in one movement.
So it seems to me that the myServer Harmony driver should use SendKeyPressAsync instead of SendCommandAsync, at least for navigation commands.
Relevant code from the open source Harmony library:
Code:
public async Task SendCommandAsync(string command, bool press = true, int? timestamp = null)
{
var text = new StringBuilder();
text.Append("action=").Append(command.Replace(":", "::"));
text.Append(":").Append("status=").Append(press ? "press" : "release");
if (timestamp.HasValue)
text.Append(":").Append("timestamp=").Append(timestamp.Value);
var xml = Xml.Element("iq")
.Attr("type", "get")
.Attr("id", _clientId + "_" + _messageId.ToString())
.Child(Xml.Element("oa", "connect.logitech.com")
.Attr("mime", HarmonyMimeTypes.DeviceCommand)
.Text(text.ToString()));
await FireAndForgetAsync(xml).ConfigureAwait(false);
}
/// <inheritdoc />
public async Task SendKeyPressAsync(string command, int timespan = 100)
{
var now =
(int)DateTime.Now.ToUniversalTime().Subtract(new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc)).TotalMilliseconds;
await SendCommandAsync(command, true, now - timespan).ConfigureAwait(false);
await SendCommandAsync(command, false, timespan).ConfigureAwait(false);
}
