Beware that you should not hardcode SF11 or SF12 into a node:

> As an aside: network providers (such as TTN) are required to actively block devices that always send on SF11 or SF12, to keep their LoRa Alliance NetID: _Devices with fixed hardcoded data rates of SF12 or SF11 must not be allowed to join the network._

Yes: [How often should a node do an OTAA Join, and is OTAA better than ABP?](https://www.thethingsnetwork.org/forum/t/how-often-should-a-node-do-an-otaa-join-and-is-otaa-better-than-abp/11192)
