Maximum scanning rate of RDR depends on the LoRaWAN datarate and the NFC payload lengths.


When the buffer contains more than one scan record, the device will pack as many scan records into the LoRaWAN™ payload as possible. 

The firmware takes care to not exceed the max LoRaWAN™ payload length allowed in the current situation.
