nRF52840: coexistance with other radios at 2.4GHz in a given product

raemond

Is there native support for hardware coex lines? If we have a WiFi chip that produces a TX Active signal, can we hold transmit from the nRF52840 till that transmit is finished?

    Hi Raemond,

    Right now, we don't have a co-ex interface support with current softdevice. It's in the plan and will come at some point next year.

    For now what you can do to reduce collision is to that active signal to hold the application from sending data. And if you use it with slave latency, the softdevice most of the time will remain quiet if there isn't any data to send. The draw back is the delay in BLE communication due to slave latency.
