DW3000 CCA Broadcast

Hello.
I’m using a DW3000 right now.
I’m sending Blink msg to Broadcast, and I’m sending it to CCA.
However, if you send it like this, there is a problem of receiving only one specific receiver.
It worked well when it was sent to IMMEDIATE rather than CCA.
What is the problem?

It sounds like CCA might be detecting the channel as busy, which could be blocking your message. You could try lowering the CCA threshold so the device is less strict about when it can transmit.

If IMMEDIATE works fine, it might just be that CCA is too sensitive in your setup. Give it a shot and see if that helps!

Thank you for your answer.
When we tested broadcasting from the DW3000 example code tx_with_cca, we confirmed that all receivers receive it. However, when CCA is sent from the code implemented in interrupt, receiver 1 receives it, but the rest receives it very occasionally. I can’t figure out what caused it.

I solved it. It became a problem that I set the dual buffer mode automatically.
