🔗 Microsoft Flight Simulator module to allow out-of-process SimConnect clients to access MSFS inner workings as if they were in-process.

jetbridge's Issues

What is the bandwidth of the SimConnect ClientData communication channel?

It would be good to know what the bandwidth of the SimConnect ClientData communication channel is. This would help answer some questions, such as whether it is viable to use a single uplink/downlink channel pair or whether we need separate channels per client. It will also help answer the question of whether splitting Protocol Data Units into multiple packets to allow for larger data transfers is possible.

Testing this should be pretty straightforward. We need a client to spam the Jetbridge Module with requests and for it to count the actual responses received per unit time. We then need to check what happens if multiple (I'd say at least 5) different clients spam the module with requests at the same time.

How to read the value of a Local (L:) SimVar?

Excuse me,
Example project works normally when setting L:Var values, but how do I get current value L:Var ?

Thanks.

Listen to Key Events

Can use https://docs.flightsimulator.com/html/Programming_Tools/WASM/Gauge_API/register_key_event_handler.htm as well as ClientEvents

Subscribe to Simulation Variables

Currently a consumer needing to get the value of a simvar at regular intervals needs to create a separate request for each refresh of each individual variable. It would be nice if a consumer was able to create their own ClientDataArea and instruct jetbridge to subscribe to certain simvars and to update their value at e.g. every frame.

Python Software Development Kit

Similar to #6, however this would would be a bit more unofficial as Python isn't officially supported by SimConnect.
This is the Python SimConnect package I've been using: https://pypi.org/project/SimConnect/

Allow longer scripts

The 128 byte packet size isn't enough to handle some event scripts for the WT CJ4, possibly others. For instance, pressing the BARO knob runs the script:

(L:XMLVAR_Baro1_ForcedToSTD) ! (>L:XMLVAR_Baro1_ForcedToSTD) 
(L:XMLVAR_Baro1_ForcedToSTD) if{ 
      (A:KOHLSMAN SETTING MB:1, mbars) 16 * (>L:XMLVAR_Baro1_SavedPressure) 
      1 (>K:BAROMETRIC_STD_PRESSURE) 
} els{ 
      1 (L:XMLVAR_Baro1_SavedPressure) (>K:2:KOHLSMAN_SET)
}

The quickest solution would be to just increase kPacketDataSize to 256 or 512. (This example was actually 257 characters)

C# Software Development Kit

There's a couple of people that have expressed interest in using Jetbridge in C#. I believe that a Client equivalent would have to be implemented in C#.
