Enthusiast Infinite-Zombie5875 has successfully enabled ESP-NOW communication on a 2009 Sony Walkman NW-X1060. The project allows the legacy device to communicate directly with ESP32 hardware without requiring a router.
A key feature of this modification is its non-invasive nature. The original Marvell wireless chip remains intact, as the developer reverse-engineered the wireless firmware's transmission and reception links to support the new protocol.
The creator implemented native C language application programming interfaces to handle ESP-NOW action frames. This setup enables the Walkman to sync data with other devices, such as the ESP-Mosaico, for shared tasks like rendering synchronized aquarium visuals.
The project is documented on GitHub, where the author provides instructions for those interested in replicating the modification on their own legacy NW-X1060 units.
