Please read this message from Hylke regarding the subject. Specifically
When creating new ABP devices on V3, you can request a DevAddr from the Network Server, and Packet Broker routing (at least of uplinks) will work fine.
As indicated above, I did, and my device address is 0x260CAD99, which per the other article you cite above clearly indicates is a v3 device in North America. Which makes sense since I set it up on the NAM1 v3 cluster.
I guess under what circumstances will following the instructions for setting up an ABP device on v3 not actually work? Is there some other bit of information that is needed here?
And to be clear, when I reprogram the device back to it’s original v2 device address and keys, it works fine. My v2 gateway is clearly working fine as it forwards the packets when the device is v2, and it receives the radio signals but can’t find any brokers when the device is V3. One thing I will note is that everyone who claims it is working for them seem to be on the Europe server (v3). Is that an important details here? Is the NAM1 server, or the ttn-router-us-west router my v2 gateway connects to, ready to go for this?
Why I haven’t migrated the gateway to v3 is because all the instructions say to do that last and migrate your devices first. I’m just following instructions here.
