ABP is only there to be compatible with the lora-alliance certification, we want devices that are certified and can be used on all networks. I understand those addresses are for experimental uses, which no networks is obligated to handle. But I don’t see how we can support ABP and get our products certified without locking them to a specific network. We got to have some kind of pre-configured DevAddr for that to work. The best for us is if we could skip ABP and still get them certified, but I don’t see how that could ever work.
