esp-wifi
A WiFi, BLE and ESP-NOW driver for Espressif microcontrollers.
Note that this crate currently requires you to enable the unstable feature on esp-hal.
Current support
If a cell contains an em dash (—) this means that the particular feature is not present for a chip. A check mark (✓) means that some driver implementation exists. A Tilde (˜) means it is implemented but buggy. An empty cell means that the feature is present in the chip but not implemented yet.
