if there is enough memory space on your board you can set the
`DEBUG_ASSERT_VERBOSE` macro [1] so you can at least find out which
assertion is hit. You can also deactivate the assertion by unsetting
the DEVELHELP macro [2] (in gnrc_networking this is set), but usually
a failed assertion points to a problem ;-).

Hope this was helpful for now.

Martine

Re: [riot-devel] Sending the udp packets does not work with the xbee module

[Wiegel, Friedrich (IAI)]

Ah ok. I did not know that the failed assertion behaves exactly like stack 
overflow. Then it must be the failed assertion. That behavior with the increase 
of the number of interfaces I find out as I tried to realize a border router. I 
really can not understand why sending, the UDP packets with two interfaces 
works and with only one not. 

With the help of your master thesis I have also tried to understand in which 
layer that problem occurs but didn't found what's going wrong. The one thing I 
know is that the gnrc_netdev2 does not receive a massage that he is now 
supposed to send something.

Is there a way to avoid the failed assertion when I increase the number of 
interfaces to 2 but use one or is it only one interfaces available?

Best regard,

Friedrich

Hi Friedrich,
then it is indeed weird, that you have to increase the number of static 
interfaces. Same goes for the stack overflow. Usually the stack should be big 
enough. Are you sure it is a stack overflow and not just a failed assertion? 
They look very similar in RIOT, since both let the node crash.

for xbee I use arduino zero board this haven’t other radio on board.

Re: [riot-devel] Sending the udp packets does not work with the xbee module

Hi Friedrich,
on what board are you using the xbee? Is there an on-board radio? It
seems like there is another interface already initialized.

Re: [riot-devel] Sending the udp packets does not work with the xbee module

[Wiegel, Friedrich (IAI)]

Hi Marine,

first of all, thanks for your answer. The payload of my udp massage is only 
"TEST", the maximum PSDU size for xbee modul is 100 bytes and my payload is 
only 80 bytes. The next thing I noticed is following, if I set 
"GNRC_NETIF_NUMOF  :=2" then I can send the udp messages. And the transceiver 
send periodically some messages as the samd21-xpro does.

Is this helpful in any way?

The Problem is when I set " GNRC_NETIF_NUMOF  :=2" I get some stack overflow if 
I want to set some global address of my interface.

Best regard,

Friedrich

the xbee module has some tricky restrictions on sent packets. Did you make sure
