Lot's of None values received

[viboux]

Very nice package, the glass cockpit demo is great, however I cannot get it to work with both the local_exemple.py and glass_server. I am getting a lot of None values returned from aq.get. I am using MSFS 2020 version 1.9.5.0 and SimConnect 0.6.1 DLL (as present in the branch).

Have you experienced any of this?

  File "C:\Dev\python\simconnect\Python-SimConnect-master\glass_server.py", line 307, in output_ui_variables
    fuel_percentage = (aq.get("FUEL_TOTAL_QUANTITY") / aq.get("FUEL_TOTAL_CAPACITY")) * 100
TypeError: unsupported operand type(s) for /: 'NoneType' and 'NoneType'

Or in some local_example.py fiddling.

Throttle = aq.find('GENERAL_ENG_THROTTLE_LEVER_POSITION:1')
altitude_f = aq.find("PLANE_ALTITUDE")
altitude_f.time = 200
while not sm.quit:
	print("Throttle:", Throttle.value)
	#altitude = aq.get("PLANE_ALTITUDE")
	
	#print ("Altitude:", altitude)
	print("Altitude_f:", altitude_f.value)
	sleep(2)

yah its a problem with performance,
I have set the defaults to use 10 _attemps in 0.4.19
this should fix.
you can play more with the _attemps in

Python-SimConnect/SimConnect/RequestList.py

Line 190 in 54f0972

def __init__(self, _sm, _time=10, _attemps=10):

aq = AircraftRequests(sm, _time=10, _attemps=10)

Thanks! Works lot better, both for local_example and glass_server. SimConnect seems to be very fiddly from what I see from many 3rd party addons sites.

I will let you know about any strange behaviour I encouter.

Thanks again!

Yep the SDK is "working" at best, not a lot of support on the SimConnect.

I'm working on asyncio, should help with performance as well, #60
