Issue

When queuing a downlink, it has been observed that some sensors in the field need multiple tries to successfully hear one.

Potential Fixes

  1. Increasing RECEIVE_DELAY1 and RECEIVE_DELAY2. Refer to pg 27 on Regional Parameters 1.0.4 document.
  2. Try existing LoRaMac procedures that are implemented in the middleware - RXTimingSetupReq and RXTimingSetupAns
