  Age Control Protocol (ACP) and its enhanced version, ACP+, are recently
proposed transport layer protocols to control Age of Information of data flows.
This study presents an experimental evaluation of ACP and ACP+ on the ESP32
microcontroller, a currently popular IoT device. We identify several issues
related to the implementation of these protocols on this platform and in
general on short-haul, low-delay connections. We propose solutions to overcome
these issues in the form of simple modifications to ACP+, and compare the
performance of the resulting modified ACP+ with that of the original protocols
on a small-delay local wireless IoT connection.
