I could not change the device's SF (for example to SF12 = DR0) by sending a link ADR request. I can see that the device even responds this MAC command with its next uplink message and confirms the datarate with Status = 6 (that means power ack and datarate ack). However the initial datarate from OTAA join is still used.
