I am fairly new to this technology. I have some confusions
- Under OTAA, how does the end device select the channel on which it can send data?
- The LoRaWAN specifications say that the join_accept message can contain an optional CF list which contains the available channels. Is there a criterion by which the end device selects the channel from the list or does it selects randomly?
- What does channel hopping mean? Does the end device reconfigure the uplink channel after a specific interval or does the channel stays the same for the entire operation of the end device?
I couldn’t find answers to these. Any kind of help will be appreciated. Thanks
