We had a bug especially in the reception path. Our recv window opening delays were being calculated on the premise that the radio has to capture 5 preamble symbols out of 8 transmitted by the base station. However, in PHY layer while setting radio rc settings, we were setting preamble length to be 8. Preamble length register needs to be configured differently for Uplink and Downlink. For uplink, we wish to transmit 8 preamble symbols whereas in the reception path we need to receive 5 preamble symbols at least out of 8. Alongwith that the maximum range of timing error may vary from platform to platform as it is based upon the crystal in the chip. We have now made these parameters configurable and have loaded them with the most optimal defaults. |
