Re: [Contiki-developers] sniffer using ATZB-24-A2 ?

[Dimitar P. <dp...@sw...>]

Hi David,

Thank you for the suggestions! I am going to check what will suit us best.

A quick note. Testing runicast example I have enabled debug at 
core/net/rime/unicast.c
and I am getting:

1.0: uc: recv_from_broadcast, receiver 1.0
1.0: unicast_send to 2.17
1.0: uc: recv_from_broadcast, receiver 2.17
 runicast message received from 2.17: MyString, seqno 0

The 3rd line doesn't looks logical to me and I saw in the code 
"recv_from_broadcast"
instead of "sent_by_broadcast" which is probably a typo in the svn trunk?

/*---------------------------------------------------------------------------*/
static void
sent_by_broadcast(struct broadcast_conn *broadcast, int status, int num_tx)
{
  struct unicast_conn *c = (struct unicast_conn *)broadcast;

  PRINTF("%d.%d: uc: recv_from_broadcast, receiver %d.%d\n",
  ...

BTW can you guys suggest good book explaining the radio protocol stuff 
around Contiki?

Best Regards
Dimitar Penev
