A link of the pinned post which you refer to?

Hi John, could you send me a link of the pinned post which you refer to?

The information he posted was incorrect for that product. But the throughput is a result of the overhead found in a ZigBee mesh network that is not being taken into account. At best, in a point to point connection, you may get 35kbps. If you do a broadcast packet it will be considerably less.
