The ESP-NOW frame length
Curiously, https://github.com/espressif/esp-now/blob/master/src/espnow/src/espnow.c#L493 enforces a check that size <= 230 (declared here). Perhaps raise an issue in the repository?

The $8 Linux Computer
In addition to ESP-Mesh protocol as mentioned in the sibling's comment, alternatively ESP-Now protocol also enabled lightweight support for direct networking without AP:

What does inter-core communication look like?
I'm browsing through the documentation of bl808 SoC and I've got some questions, and I would be glad to have some answers as it is something new to me and I'm just trying to finally get my head around it. While answering, please bear in mind that if you don't know this SoC but have knowledge from other solutions I will be also supper happy, because I'm trying to grasp the general idea. This SoC is just an example.

The $8 Linux Computer
Stay tuned, according to the Bouffalo Lab BL808 SoC datasheet (page 90) series numbering system that the board is based on, they will probably have more RAM and ROM capacity in the later versions of the SoC:
