 "title": "WiFi association beats ESP-NOW only past a few hundred kilobytes per session, and the break-even moves by sixty times depending on whether you pin the channel",
 "symptom": "The throughput numbers make the choice look obvious. An associated link moves 5.8 to 14 Mbps against ESP-NOW's 0.686 Mbps, which is eight to eighteen times faster, so association looks like the clear winner. Applied to small sporadic messages it is dramatically the wrong choice, and the reason never appears in a throughput benchmark.",
