[Tinyos-help] am_group_t tinyos2.x

[Luca Briggi]

Hi everybody, on lesson3 of the tutorial and on tep111 (message_t) and
tep116 (Packet Protocols) there is no mention of the use made by
active message sending and receiving interface of the node group
identifier. On AMpacket interface comments is written that tipically
nodes only receive packets whose AM group field matches their own. Is
that done by default? How can i set the node group at installation
time?

Thanks,
Luca
