Can sequential messages be received in < 1ms?

2.3.1.142 on a C7

@bobbyD @gopher.ny

I'm troubleshooting an issue with a custom Zigbee device. It should be sending 6 bytes every 5 minutes. The data is a measurement so it is likely a number of messages will be identical.
periodically the hub reports split messages often within a ms or less.

Can you tell from the below log data if the issue is likely from the source or from the decoding by the Hub? I suspect it is from the source but any supporting (or not) opinion would be helpful.

Thanks
John

below is same data as screenshot. Might be more readable.

i only see one read attribute set that's a few ms after another one and the second of them appears to contain invalid data.
It's not likely this is being generated by the hub, but the only way to find out for sure is by sniffing the traffic for this device.
