nRF52 missing address events

I am using the nRF52 in 2Mbps proprietary mode. I am running my own custom stack to maximize data throughput. There are no re-transmissions in my design. I have a loop of code that transmits a few packets in a row followed by an acknowledge received packet. I have noticed that address events are being missed randomly even though both the PTX and PRX are setup properly and all timing meets specification.

Is anyone else experiencing this?

See below.

Yellow trace is PTX transmitting. Blue trace is PRX receiving. Wider pulse is START task. Narrow pulse is ADDRESS event.

Both radios were in their corresponding TX/RX idle state prior to sending the START task. Also the PTX and PRX were connected with a SMA cable.

  • I don't have an exact percentage but as frequent as 10ms and sometimes up to several seconds. I have not tried the lower bit rates because my project requires 2Mbps. I do have a support case with the factory and hope to get some answers soon but I thought that I would also reach out to the Nordic community to see if anyone else has experienced this.
