Hey all,
I've a question that I'd like you to answer me. Let's start by a small
protocol/schema.
Ar ............. SB ............. Cr ..............Base
Given the situation, imagine that sensor SB wants to relay some information to
the Base, but this info should be sent just using Ar or Cr. I.e just those
sensors Ar and Cr can relay this info to the Base. The SB sensor uses the
command CC2420Packet.getLqi(*msg) to get some Link quality Indicator
measurements of messages from Ar and Cr (let's assume, a type of a special
beacon message). My question is: Does this command interface Gives the Link
Quality Indicator in terms of SNR? or some other parameter/measurement?
Let me assume another breaking parameter that, each control info from Cr and
Ar contains a value dtb (distance to the Base), in this case Cr is obviously
closer to the Base. The metric is that each hop it's equal to 1.
Ar(dtb) = 2; Cr(dtb) = 1;
typedef nx_struct{
nx_uint8_t dtb; //distance to the Base
nx_uint8_t type; //info message type
nx_uint16_t rid; //Router Id (Ar or Cr NodeID's)
}beacon_t;
Thanks in Advance.
-Antonio
