Detailed Description

This module includes the platform abstraction for a radio frame.

Typedef Documentation

otRadioCaps

typedef uint8_t otRadioCaps

This type represents radio capabilities.

The value is a bit-field indicating the capabilities supported by the radio. See OT_RADIO_CAPS_* definitions.

otRadioCoexMetrics

The following are valid radio state transitions:

(Radio ON) +----——+ Enable() +-——+ Receive() +---——+ Transmit() +----——+ | |-----——>| |-----——>| |--------——>| | | Disabled | | Sleep | | Receive | | Transmit | | |<-----——| |<-----——| |<--------——| | +----——+ Disable() +-——+ Sleep() +---——+ Receive() +----——+ (Radio OFF) or signal TransmitDone

During the IEEE 802.15.4 data request command the transition Sleep->Receive->Transmit can be shortened to direct transition from Sleep to Transmit if the platform supports the OT_RADIO_CAPS_SLEEP_TO_TX capability. This structure represents radio coexistence metrics.

otRadioState

This structure represents the state of a radio.

Initially, a radio is in the Disabled state.
