Can you explain the timestamps at the sniffer, are these calculated on sniffer or has anything to do with coordinator or endpoint?
The timestamp is the number of milliseconds from the previous message.
The first message will always be 0, the second message will have the
time from the first message, the third message shows the time from the
second message, and so on.
The manual mentions that in sniffer mode, the device ID is reported “of the associated endpoint” (18.104.22.168). Does that mean it cannot sniff message from other coordinators?
Yes, it will sniff out any packets whether it comes from a coordinator or endpoint. The sniffer is a special diagnostic mode and thus is not operating as either a coordinator or endpoint itself.
What is the difference between a coordinator and an endpoint?
The SubGig standard defines a very simple star topology where one coordinator device speaks to multiple endpoints. The coordinator is generally controlled by a host processor, typically on a gateway connected to the cloud. A device acting as a ...
Can the coordinator queue one message for each endpoint, or does it only queue one message in total?
There is a single slot in the queue for each registered endpoint. Thus, multiple endpoints may have queued messages simultaneously, but only one message can be queued for each endpoint at any given time.
In order to save power, can the coordinator send a PL command over the air to each endpoint?
No this is not a way to remotely change the power level. Also, we do not allow coordinators to dynamically change the listen window for endpoints. The reason for this is that a sleepy endpoint is typically battery powered and dynamically extending ...
Does the coordinator need to have its sleep mode enabled to send queued packets to sleepy endpoints?
No and you typically don’t want to put the coordinator into sleep mode. When the queue packet command is used the coordinator will check to see if the endpoint is sleepy, and if it is not then it will send the message immediately. In other words, the ...
