As LinkAdrReq commands also control the nbTrans (number of retransmissions) and this field is an integral component to how the network manages (in conjunction with data-rate and transmit-power) the effective performance of the end-device, the field must also be controlled during ADR back-off. This change will require the end-device to reset nbTrans to its default value of one during the last step of ADR back-off. This point of control was chosen as nbTrans typically improves performance (unlike typical data-rate and transmit-power controls) and the last step of the ADR back-off algorithm is to revert all ADR controlled variables to defaults.
