Xpnd problems

[Francois]

first of all, well done for your work. the product is really great.
I use it with the realsimgear it's a delight!

I nevertheless get some problems:
1. When I set a new transponder code. The value is correctly set but the code displayed on the gtn750 is always set to 0001.
no depend of aircraft choosen

2. when I select the xpnd mode to ´on' or ´alt' mode immediatly go back to ´standby'


anybody got the same issues ? do you have any workaround or idea to fix it?

regards

François
