RX parameters (re)configuration

ChirpStack supports the (re)configuration of the following RX parameters:

  • RX delay the delay between the end of TX and the first reception slot.
  • RX1 data-rate offset the offset used to calculate the RX1 data-rate, based on the uplink data-rate.
  • RX2 data-rate the data-rate used for the RX2 receive-window.
  • RX2 frequency the frequency used for the RX2 receive-window.

The first three parameters are sent to the device as part of the OTAA join-accept frame. The RX2 frequency parameter is pushed to the device using the RXParamSetupReq mac-command.

Note: on a ChirpStack configuration change, the new parameters will be pushed to the device using the RXParamSetupReq or RXTimingSetupReq mac-commands at the first opportunity.
