Saitek Proflight - Lua for Saitek BIP not working

[michel78320]

Hi,

I am writing a lua script for my Saitek Proflight modules.

Win10 + MSFS + FSUIPC 7.3.7 (registred).

Everything works perfectly for the Switch Panel, for the Multi Panel and for the Radio Panel, except this message :

   391500 **** DevCom read/write threads still running - will exit anyway but could cause issues...
   391813 **** DevCom Read thread terminated
   392313 **** DevCom read/write threads still running - will exit anyway but could cause issues...

Same message for all Panel, but this does not disturb the operation.
I can read the buttons, and display the values in the screens (alt, speed ...).
Is this error message important?

I have a big problem with the BIP :

The "com.writefeature" always return "0" and nothing happens on the BIP.

Here is a test script :

Vendor = 0x06A3
Product1 = 0x0B4E    --  BIP
Product2 = 0x0D67    -- Switch Panel
Device = 0
Report = 0

ipc.log ("===========================  BIP   =========")
dev1, rd1, wrf1, wr1, init1 = com.openhid (Vendor, Product1, Device, Report)

ipc.log ( "================================ dev1 = " .. dev1)
ipc.log ( "================================ rd1 = " .. rd1)
ipc.log ( "================================ wrf1 = " .. wrf1)
ipc.log ( "================================ wr1 = " .. wr1)

s = string.char (6 , 2 , 2 , 2, 0 , 0 , 0 )
n = com.writefeature (dev1, s, wrf1)
ipc.log ("===========================  BIP writefeature  ==== n = " .. n)

ipc.log ("===========================  Switch module   =========")
dev2, rd2, wrf2, wr2, init21 = com.openhid (Vendor, Product2, Device, Report)

ipc.log ( "================================ dev2 = " .. dev2)
ipc.log ( "================================ rd2 = " .. rd2)
ipc.log ( "================================ wrf2 = " .. wrf2)
ipc.log ( "================================ wr2 = " .. wr2)

s = string.char (0 , 7)
n = com.writefeature (dev2, s, wrf2)
ipc.log ("===========================  Switch module writefeature  ==== n = " .. n)

com.close (dev1)
com.close (dev2)
	

Here is the log

Do you have an idea of what is wrong ?
Thanks in advance.

Not if everything is working - its just an informative message that indicates the devcom threads could not be closed on the first attempt. You can safely ignore these.

No - I don't have any experience with the saitek BIP, sorry.

thank you for your answer.

Can you explain to me what is the number returned by "com.writefeature"   ?
Is it sent by the device?

By the way, com.writefeature does not use "wrf"
With Switch Panel, wrf = 2

s = string.char (0 , 3 , 2 , 2, 0 , 0 , 0 )
n = com.writefeature (dev1, s, 1)

returns n=2 ! and two leds light up (correct)

It is as documented: The returned value gives the number of bytes actually sent (or at least, placed in the buffer).

returns n=2 !

The com.writefeature function just passes through to the windows HidD_SetFeature function. There are some 'correct size' checks and the passed in size may be adjusted - you can skip this parameter and the correct size should be used (I think!). The returned value will be what was actually written to the device' buffer.

You could try logging HID activity to see what is happening. From the Log->Custom menu, enter 0x200. This should then log all HID activity.

OK. I understand all this.
Thank you for the explanations.
