void otPlatRadioEnableSrcMatch |
( |
otInstance * |
aInstance, |
|
|
bool |
aEnable |
|
) |
| |
Enable/Disable source address match feature.
The source address match feature controls how the radio layer decides the "frame pending" bit for acks sent in response to data request commands from children.
If disabled, the radio layer must set the "frame pending" on all acks to data request commands.
If enabled, the radio layer uses the source address match table to determine whether to set or clear the "frame
pending" bit in an ack to a data request command.
The source address match table provides the list of children for which there is a pending frame. Either a short address or an extended/long address can be added to the source address match table.
- Parameters
-
[in] | aInstance | The OpenThread instance structure. |
[in] | aEnable | Enable/disable source address match feature. |

- Parameters
-
[in] | aInstance | The OpenThread instance structure. |
[in] | aScanChannel | The channel to perform the energy scan on. |
[in] | aScanDuration | The duration, in milliseconds, for the channel to be scanned. |
- Return values
-
OT_ERROR_NONE | Successfully started scanning the channel. |
OT_ERROR_NOT_IMPLEMENTED | The radio doesn't support energy scanning. |
void otPlatRadioEnergyScanDone |
( |
otInstance * |
aInstance, |
|
|
int8_t |
aEnergyScanMaxRssi |
|
) |
| |
The radio driver calls this method to notify OpenThread that the energy scan is complete.
This function is used when radio provides OT_RADIO_CAPS_ENERGY_SCAN capability.
- Parameters
-
[in] | aInstance | The OpenThread instance structure. |
[in] | aEnergyScanMaxRssi | The maximum RSSI encountered on the scanned channel. |
The radio driver calls this method to notify OpenThread to process transmit security for the frame, this happens when the frame includes Header IE(s) that were updated before transmission.
This function is used when feature OPENTHREAD_CONFIG_HEADER_IE_SUPPORT
is enabled.
- Note
- This function can be called from interrupt context and it would only read/write data passed in via
aFrame
, but would not read/write any state within OpenThread.
- Parameters
-
[in] | aInstance | The OpenThread instance structure. |
[in] | aFrame | The radio frame which needs to process transmit security. |
int8_t otPlatRadioGetRssi |
( |
otInstance * |
aInstance | ) |
|
Get the most recent RSSI measurement.
- Parameters
-
[in] | aInstance | The OpenThread instance structure. |
- Returns
- The RSSI in dBm when it is valid. 127 when RSSI is invalid.
Get current state of the radio.
This function is not required by OpenThread. It may be used for debugging and/or application-specific purposes.
- Note
- This function may be not implemented. It does not affect OpenThread.
- Parameters
-
[in] | aInstance | The OpenThread instance structure. |
- Returns
- Current state of the radio.
Get the radio transmit frame buffer.
OpenThread forms the IEEE 802.15.4 frame in this buffer then calls otPlatRadioTransmit()
to request transmission.
- Parameters

[in] | aInstance | The OpenThread instance structure. |
- Returns
- A pointer to the transmit frame buffer.
bool otPlatRadioIsEnabled |
( |
otInstance * |

- Returns
- TRUE if the radio is enabled, FALSE otherwise.
Transition the radio from Sleep to Receive (turn on the radio).
- Parameters
-
[in] | aInstance | The OpenThread instance structure. |
[in] | aChannel | The channel to use for receiving. |
- Return values
-
OT_ERROR_NONE | Successfully transitioned to Receive. |
OT_ERROR_INVALID_STATE | The radio was disabled or transmitting. |
The radio driver calls this method to notify OpenThread of a received frame.
- Parameters
-
[in] | aInstance | The OpenThread instance structure. |
[in] | aFrame | A pointer to the received frame or NULL if the receive operation failed. |
[in] | aError | OT_ERROR_NONE when successfully received a frame, OT_ERROR_ABORT when reception was aborted and a frame was not received, OT_ERROR_NO_BUFS when a frame could not be received due to lack of rx buffer space. |
Transition the radio from Receive to Sleep (turn off the radio).
- Parameters
-
[in] | aInstance | The OpenThread instance structure. |
- Return values
-
OT_ERROR_NONE | Successfully transitioned to Sleep. |
OT_ERROR_BUSY | The radio was transmitting. |
OT_ERROR_INVALID_STATE | The radio was disabled. |
Begin the transmit sequence on the radio.
The caller must form the IEEE 802.15.4 frame in the buffer provided by otPlatRadioGetTransmitBuffer()
before requesting transmission. The channel and transmit power are also included in the otRadioFrame structure.
The transmit sequence consists of:
- Transitioning the radio to Transmit from Receive.
- Transmits the psdu on the given channel and at the given transmit power.
- Parameters
-
[in] | aInstance | The OpenThread instance structure. |
[in] | aFrame | A pointer to the frame to be transmitted. |
- Return values
-
OT_ERROR_NONE | Successfully transitioned to Transmit. |
OT_ERROR_INVALID_STATE | The radio was not in the Receive state. |
The radio driver calls this function to notify OpenThread that the transmit operation has completed, providing both the transmitted frame and, if applicable, the received ack frame.
- Parameters
-
[in] | aInstance | The OpenThread instance structure. |
[in] | aFrame | A pointer to the frame that was transmitted. |
[in] | aAckFrame | A pointer to the ACK frame, NULL if no ACK was received. |
[in] | aError | OT_ERROR_NONE when the frame was transmitted, OT_ERROR_NO_ACK when the frame was transmitted but no ACK was received, OT_ERROR_CHANNEL_ACCESS_FAILURE tx could not take place due to activity on the channel, OT_ERROR_ABORT when transmission was aborted for other reasons. |
The radio driver calls this method to notify OpenThread that the transmission has started.
- Note
- This function should be called by the same thread that executes all of the other OpenThread code. It should not be called by ISR or any other task.
- Parameters
-
[in] | aInstance | A pointer to the OpenThread instance structure. |
[in] | aFrame | A pointer to the frame that is being transmitted. |
