Convert from dBm scale to RSSI.
The RSSI calculation is based on the IEEE 802.15.4 2020 specification and it's represented as one octet of integer.
RSSI equal to zero maps to -174 dBm and has the same scale as dBm (1 RSSI step == 1 dBm). Therefore an RSSI value of 254 maps to +80 dBm.

Check whether a frame pass the IEEE 802.15.4 frame filter.
A frame passes the frame filter only if:
[in] | mhr | MAC header (PSDU) |
[in] | pan | PAN ID of the frame filter. |
[in] | short_addr | Short Address of the frame filter. |
[in] | ext_addr | Extended Address of the frame filter. |

Convert from RSSI scale to dBm.
The RSSI calculation is based on the IEEE 802.15.4 2020 specification and it's represented as one octet of integer.
RSSI equal to zero maps to -174 dBm and has the same scale as dBm (1 RSSI step == 1 dBm). Therefore an RSSI value of 254 maps to +80 dBm.

buf
.If dst
is NULL the IEEE802154_FCF_ACK_REQ will be unset to prevent flooding the network.
[out] | buf | Target memory for frame header. |
[in] | src | Source address for frame in network byteorder. May be NULL if IEEE802154_FCF_SRC_ADDR_VOID is set in flags . |
[in] | src_len | Length of src . Legal values are:
|
[in] | dst | Destination address for frame in network byteorder. May be NULL if IEEE802154_FCF_SRC_ADDR_VOID is set in flags . |
[in] | dst_len | Length of dst . Legal values are:
|
[in] | src_pan | Source PAN ID in little-endian. May be 0 if IEEE802154_FCF_PAN_COMP is set in flags . Otherwise, it will be ignored, when IEEE802154_FCF_PAN_COMP is set. |
[in] | dst_pan | Destination PAN ID in little-endian. |
[in] | flags | Flags for the frame. These are interchangeable with the first byte of the IEEE 802.15.4 FCF. This means that it encompasses the type values, IEEE802154_FCF_SECURITY_EN, IEEE802154_FCF_FRAME_PEND, and IEEE802154_FCF_ACK_REQ. |
[in] | seq | Sequence number for frame. |
The version field in the FCF will be set implicitly to version 1.
