esp-radio
A WiFi, BLE and ESP-NOW driver for Espressif microcontrollers.
This package also includes low-level IEEE 802.15.4 driver for the ESP32-C6 and ESP32-H2
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.
