I am just looking for a way to read the additional data appended in the ACK by the listening TCP endpoint.
For context, in our project, our server (the listening TCP endpoint) sends a custom string (e.g., "complete") as sort of an acknowledgement to the connecting TCP endpoint (in our case, a full-thread device) to inform it that all the TCP packets have been received. Currently, when I send a message to the server (e.g., tcp send hello), what is displayed on the cli of the full-thread device is this:
> tcp send hello
> TCP: Reached end of stream
The custom string "complete" is missing.
