Do I have to ReJoin after being out of range

End Devices (Nodes)

Hello All,

I am developing an GPS based data tracker with a WioE5 module to sent battery voltages, temperatures etc. to a NodeRed dashboard.

My question, do I have to rejoin the TTN network after being out of range or after repowering.
BTW I used Activation by personalization (ABP)

Thanks in advance,
Michel (from Belgium)

You can’t.

Because you don’t join when using ABP.

But if you did join because you used OTAA, no, as long as the device hasn’t had the power cycled on it so it still has the join session you are fine.

Information on the differences can be found https://www.thethingsnetwork.org/docs/lorawan/end-device-activation/
