Hi Thomas, Diego, I agree that LQI should be there as well. I update here the list with Thomas suggestions. For each known neighbor: -ID -AVG RSSI in a running window -Latest RSSI -AVG LQI in a running window -Latest LQI -Num TX packets (option in case there is communication with that neighbor) -Num ACK packets (option in case there is communication with that neighbor) -Num RX packets (option in case there is communication with that neighbor) -Last ASN when it heart about that neighbor Other fields -Num links in the Schedule to that neighbor -For each link PDR -For each Queue: - Avg Queue length in a running window - Max Queue length in a running window (peak) - Current Queue length (?) -Time source parent -ID -Avg clock drift (correction done) in a running window -Latest clock correction -Parent changes (counter of how many times I changed my time source parent) -Option Flag (weather there are optional TLV fields) +(TLV objects)* Hope this makes sense. cheers!
