Questions about how the RAK2270 works

Hello, I would like to ask for confirmation about the default behavior of the RAK2270 when used in its original condition, without any firmware modification.

  1. When I purchase a RAK2270 and power it on for the first time, will it automatically join the LoRaWAN network that I have already configured?
  2. For example, if my RAK2270 is operating normally, but then the battery runs out, and I later insert a new battery, will it automatically rejoin the same LoRaWAN server/network that it had previously joined and sent uplink data to, so that the operation can continue normally?

The condition is that the RAK2270 is purchased from your store and used as-is, without any firmware modification.
I just want to buy the RAK2270 so I can insert batteries to run it, and when the batteries run out and I replace them with new ones, it will continue to work.

Thank you.
