few days ago i post one request about ACK on Tmote Sky.
I tried to follow Joe's advice but now i have other problems...
-Boomerang and SPC in particular uses a software ACK (many thanks to Phil Levis for this..). Reading all SP directory i found that the CC2420 hardware ACK (using AUTOACK) is not used.
My application uses old Send interfaces, and so the wrapper adapts them to SPsend: i modify the SPsend.Send inserting always a RELIABLE flag, so in theory
every send call uses reliability?
- How can i recognize ACKs at upper layers? I need to tx alarms that must be ACKED (the idea is to dequeue them only when an ack is received).
- I use 2 kind of different messages: Alarms and Polling. Is possible to distinguish ACKs by AM type (like data msg)? For hardware ACK i don't think so... but with SPC?
- The last... Is possible to use old Genericomm or use hardware ACK using SPC...How?
Thank you very much
