Hi Haoyang,

I'm not quite sure if I got your question. But I can try to solve some 
confusion. Se me comments inline!

Thanks Peter,

I encountered an question about DEFAULT program.

the _netif_send is the underlying function for txtsnd, it use 
genre_netapi_send(dev, pkt) to send the packet. But in pkt_dump 
process running background, I notice the _eventloop(void *arg), is the 
codes in charge of printing. The question is:


- The command "txtsnd" in the default example *sends* plain data over an 
interface, without using other protocols
- netapi is an IPC mechanism to communicate between modules/threads in 
the network-stack
- pkd_dump you can understand as a *receiver* thread. You register it 
for some kind of protocol and if this kind is received, pkt_dum just 
prints the packets contents to the console




gnrc_netapi_send is sending GNRC_NETAPI_MSG_TYPE_SND, but in 
_eventloop, it is the GNRC_NETAPI_MSG_TYPE_RCV type, because the 
stdout result shows “PKTDUMP: data received:”. Is there any problem?


- GNRC_NETAPI_MSG_TYPE_SND and GNRC_NETAPI_MSG_TYPE_RCV are two types of 
the communication mechanism netapi. Like the names already say, one type 
is used when there is data to send (network-stack from top to bottom) 
and the other is used when there is data received (network-stack bottom 
to top).


If you are still confused, could you explain your scenario and the 
existing problem in a bit more detail?




Thanks,
Haoyang



Cheers,
Peter

Hi Haoyang,

yesterday it was too late for joining the session. We've already 
closed the conference at that time. Usually we start the Hack'n'ACK 
about 17:30 p.m. CET.


If you want to join discussions you can also follow the virtual 
meetings that take place on wednesdays at 2 p.m. CET *if* someone put 
content in a prepared pad. If I see it correctly this pad should be 
the one for the next potential conference:

Alternatively you can use this list to discuss anything :-).

Best,
