Title: Bug in speed dec api when using Cuety app & API
Post by: TimoteusR on April 18, 2020, 11:04:38 AM
Hi,

I have a made a driver for cuety LPU-2 driver for RTI Apex https://www.rticorp.com/ (https://www.rticorp.com/). While working on it I noticed that there seems to be some odd behaviour in the TCP/UDP playback speed decrement api when the windows Cuety app is running at the same time.

Make a speed adjustment in the windows Cuety app tp playback 1

Response
Code: [Select]
pb01/sp=-90\00
Send
Code: [Select]
pb01/sp=--5
Response
Code: [Select]
pb01/sp=-95\00
pb01/sp=-90\00

The speed gets decreased but instantly it increases back. It seems to happen when the decrement value is 0-5. If I send --6 then it works

It also happens if I try to set a value lower than -50 with the decrement api.

How to test
First way
- Change speed in Cuety windows app
- Send speed --5 commands thru the api
-> The api command sets speed but it gets reset instantly

Second way
- Set speed to 0 thru api
-> Send speed --5 commands thru the api
- Once it hits -50 it won't go lower

Hi,

Cool that you made a driver! Can you share it with us? :)
I've tried to reproduce the issue you are describing, but for me it seems to work. So I have a few questions...
-Which firmware is the LPU-2 running?
-Which version of Cuety are you using on Windows?
-Are you using TCP or UDP?
-Can you share a printscreen of the monitor page of the LPU-2 showing the issue?
-Is there a way for me to test this driver, without RTI hardware? (Some sort of emulation mode?)

Many thanks for your help and feedback,

Greetings,
Bootsy
