Re: LF: EbLaunch - an easy application for managing Window's EbNaut-rx

[N1BUG <paul@n1bug.com>]

Hello Domenico,

I am not yet using EbNaut. Seems not any time soon for me. But I am
very interested.

I want to say thank you for taking the time to develop and share
this application. As I said before, if EbNaut is ever to become a
mainstream mode on LF it must be made easier to use and the hardware
setup easier to understand and build.

I have no possibility to receive EbNaut over the air but I could
install and test this under Windows 10 with the included sample
file. I will try it when I get a bit of free time, hopefully today.

Your application is not stupid! It is an important step toward
making EbNaut more user friendly and therefore accessible to more
people!

73,
Paul N1BUG
