Hi Arjan,
Coming back to the discussion about OTAA and ABP, I got working what I wanted working and made some choices. I referred to joining first using OTAA and then subsequent joins using ABP. My problem was that I switch off the radio (RN2483) so when I switch it on again I must do some kind of jion, otherwise it wont transmit. I found the article I was talking about once more:

Essentially, if you do a join OTAA, then transmit something, then do a ‘mac save’
you can remove power to the radio, reapply power, do a ‘mac join abp’ and the network
will not ‘know’ you removed the power - it will look like a continuation of the OTAA
session. When you remove power (as I do!) this seems to be the power-cheapest way to rejoin.
I think using this techniek I still keep the advantages of being able to join another network by
telling my node the new keys and instructing it to repeat the initial OTAA join.
Perhaps you could tell me what do you think of this techniek ? Am I missing anything ? - it
works on my prototype, have not got round to testing the ‘switch’ to a new network as yet.
regards,
Dave
