S2-LP Receiving Packets in Error

RLind.3
Associate III

Hi there,

I am using an S2-LP transceiver on a custom board. I have it transmitting and receiving packets correctly using a basic format packet. However, if I leave the transceiver in RX mode, the 'RX buffer almost full' interrupt fires intermittently even when I haven't sent it a packet. When I read the RX FIFO, the data is meaningless. How do I stop the transceiver from receiving these 'packets'? I used the S2-LP DK GUI to set most of my registers, and my preamble and sync word values appear to be set correctly. I have also enabled the SQI filter and set the threshold to 0 - a perfect sync word match is required. Due to this, I am not sure how an erroneous packet could be received?

Thanks,

Rebecca
