Enumeration Type Documentation

enum radio_state_t

Current state of the radio.

Note
This radio driver is very minimal in that it does not follow a state machine. It is up to the MAC layer to ensure that the different radio operations are called in the righr order. The radio keeps a state for debugging purposes only.
Enumerator
RADIOSTATE_STOPPED 

Completely stopped.

RADIOSTATE_RFOFF 

Listening for commands, but RF chain is off.

RADIOSTATE_SETTING_FREQUENCY 

Configuring the frequency.

RADIOSTATE_FREQUENCY_SET 

Done configuring the frequency.

RADIOSTATE_LOADING_PACKET 

Loading packet into the radio's TX buffer.

RADIOSTATE_PACKET_LOADED 

Packet is fully loaded in the radio's TX buffer.

RADIOSTATE_ENABLING_TX 

The RF TX chaing is being enabled (includes locking the PLL).

RADIOSTATE_TX_ENABLED 

Radio ready to transmit.

RADIOSTATE_TRANSMITTING 

Busy transmitting bytes.

RADIOSTATE_ENABLING_RX 

The RF RX chain is being enabled (includes locking the PLL).

RADIOSTATE_LISTENING 

RF chain is on, listening, but no packet received yet.

RADIOSTATE_RECEIVING 

Busy receiving bytes.

RADIOSTATE_TXRX_DONE 

Frame has been sent/received completely.

RADIOSTATE_TURNING_OFF 

Turning the RF chain off.
