Hi,

[quote user="TML_YT"]

After I posted my post, I found out that there had been similar content in the past. I found out that it is not possible to start the ESB with PPI alone.
I am very disappointed because PPI is a powerful feature.

You are right. PPI is very powerful, but unfortunately ESB requires the CPU to handle the protocol, as most of the features are implemented in software.

Always happy to help out. I hope you have a wonderful day!

Kind regards,

Håkon

Reply, thank you.

I will try triggering RF transactions by certain event interrupts as you suggested.

Thank you very much.

Hi,

ESB is a protocol that sets up several states, cpu wise, and thus it is not setup to start the radio solely based on PPI.

If you look into the function itself, you can see that it sets up the radio, buffers, and many other features/requirements towards the RF protocol.

I would recommend that you enable a interrupt on the event you want to trigger a RF transaction on.

Kind regards,

Håkon
