UdpServer_Echo sample code: doesn't sent string

[CFornari]

When I execute the "UdpServer_Echo" example, I can successfully receive the packages that are coming from my computer and they are printed at the serial terminal.

Although the function udp.sendStringTo() returns true, no package is received in my computer.

I used netcat, tcpdump, wireshark and a custom software I made, none of those reported any udp package activity in the port I specified.

Can someone reproduce the behavior?

I'm using the develop branch.
commit number: 414bf05

@Oshio09 please, check PR #1775.

@slaff yes its working.
But when using the makefile in the "UdpServer_Echo" folder, what its been compiled is the blink example. This also happens with the original commit (414bf05).
I copied the application.cpp to a folder with the Makefile and component.mk files copied from the blink example for it to work.
Can you confirm if this is a problem or a mistake that I'm making?

I haven't experienced such an issue. I usually compile examples by typing:

cd $SMING_HOME/../samples/UdpServer_Echo
make

And all is good. For this issue I actually used the Host emulator to test it on my local system. And I did this to make it run locally (on the Host)

# To setup the virtual network I use
$SMING_HOME/Arch/Host/Tools/setup-network-linux.sh wlan0 
# Then compile as usual
cd $SMING_HOME/../samples/UdpServer_Echo
# with SMING_ARCH=Host
make SMING_ARCH=Host
# and then test it using
make run

@slaff I followed your steps and everything works perfectly. Thank you for your assistance.
I didn't knew about the Host functionality, I believe it will be worth some mention to this feature at the Readme.md for newbies like me to discover about this in a easier way.
