I have some questions that I cannot understand.
First, is the device address automatically generated when the node joins, even though the same node is used? That is, when I reset my unique lora node, the lora node’s devaddr is different with the last time?
Second, when I try to use my lora node to transmit data to chirpstack, I see on chirpstack that the speed of receiving node data packets is very slow, however, on the gateway side, the speed of receiving data from other lora nodes is very fast.I only received data from my node in about three minutes. Why about it ? I am a beginner, thank you so much!
