How to add custom content in the ASK package sent by ESB's RX to TX

[mingjkl]

I hope to add custom data to the ASK package returned to TX in the ESB application. How can I add it in the input? How should the tx side read the custom data.

Hi Jianming, 

Could you give more information about the chip you use and the SDK you use ? 

If you are using NCS , you can have a look at the esb_write_payload() function. 

"When the module is in PRX mode, the payload is queued for when a packet is received that requires an acknowledgement with payload."

So what you need to do is to call esb_write_payload() function with the payload you want to include in the ACK package before you receive the incoming package. 

You can have a look at the documentation here:

I read the manual carefully again and operated it again, I already know how to use it, thank you.
