Hi Martine,
It solved the issue! Thank you for your advice.
I’m now sending packets by Xbee.
Now I have the inverse problem: A UPD packet arrives on the other device and is
properly decoded:
[xbee] isr: data available, waiting for read
[xbee] recv: reading size without dropping: 85
[xbee] recv: consuming packet: reading 85 byte
It contains the correct destination IPv6 address but nothing happens before the
mentioned debugs. Did I miss any netdev configuration? I already have a running
UDP server as described in the examples.
Thank you,
Tiago

Hi,
Mh, curious, the bug of Xbee that I was thinking of shouldn't have been in
effect at this point, but regardless it might be a good idea to get to current
master or the current release (2018.01), since the version you are using is
almost a year old.
Cheers,
Martine

Hi Tiago,
can you tell us on which git revision you are on? There used to be a bug in
xbee, pretty much as you described, but that should be fixed as of the latest
release (and in current master).
Cheers,
Martine

Hey guys,
I’m trying to send a UDP packet but the xbee module is not invoked.
I’m using a mbed lpc1768 board with a Xbee radio and the ‘ps’ output is the
following:
> ps
pid | name | state Q | pri | stack ( used) | base
| current
- | isr_stack | - - | - | 512 ( 336) |
0x100000c8 | 0x10000290
1 | idle | pending Q | 15 | 256 ( 128) |
0x1000050c | 0x1000058c
2 | main | running Q | 7 | 1536 ( 732) |
0x1000060c | 0x10000a7c
3 | pktdump | bl rx _ | 6 | 1536 ( 236) |
0x10001d58 | 0x1000226c
4 | 6lo | bl rx _ | 3 | 1024 ( 268) |
0x10002358 | 0x1000264c
5 | ipv6 | bl rx _ | 4 | 1024 ( 292) |
0x100015f0 | 0x100018cc
6 | udp | bl rx _ | 5 | 1024 ( 484) |
0x100028e4 | 0x10002bdc
7 | coap | bl mbox _ | 6 | 1024 ( 584) |
0x100011ec | 0x100013a4
8 | xbee | bl rx _ | 2 | 1024 ( 540) |
0x10000c6c | 0x10000f74
| SUM | | | 8960 ( 3600)
When I try to send a UDP packet using
‘gnrc_netapi_dispatch_send(GNRC_NETTYPE_UDP, GNRC_NETREG_DEMUX_CTX_ALL, ip)’
the invoked pids are, by this order, 6 (udp) and 5 (ipv6). After this, the
packet is not transmitted.
Note: Xbee module is working (it transmits information if called directly by
UART).
Thanks in advance,
Tiago Carvalho
