Is the IEEE 802.15.4 stack oficially docummented?

[gruvineo]

I found an open source HAL for the IEEE802.15.4 stack in Rust: https://github.com/esp-rs/esp-ieee802154 but I cannot find detailed information about this stack in the datasheet. For example, I cannot find for which thing is each register. Is it available publicly? How were they able to write this stack?

Hello @gruvineo,

The register-level information for the IEEE 802.15.4 stack, similar to Wi-Fi/BLE, is proprietary and is not disclosed publicly.
