nordic,nrf-radio¶
Vendor: Nordic Semiconductor
Description¶
Nordic nRF family RADIO
dfegpio[n]-gpios properties provide GPIO pins to the radio peripheral. These
GPIO pins are used to drive antennas switching by Radio Direction Finding
Extension. E.g. to use 12 antennas 4 GPIO pins must be provided;
4 GPIO pins support switching up to 16 antennas.
The dfegpio[n] properties are used to initialize the PSEL.DFEGPIO[n]
registers. None of the dfegpio[n]-gpios properties are marked required,
since which Radio PSEL.DFEGPIO[n] registers will be used to drive antenna
switches depends on the use case.
Nevertheless, at least two antennas must be available. That means at
least one dfegpio[n]-gpios property must be provided, to give the radio
the possibility to switch between two antennas.
Properties¶
Properties not inherited from the base binding file.

|
Number of available antennas.
Value zero means no antenna available. If provided value different than
zero, it must be greater or equal to two.
This property is required. |
|
|
Antenna switch pattern to be used for transmission of PDU before start
of transmission of Constant Tone Extension.
This pattern is stored in SWITCHPATTERN[0] before store actual antenna
switching patterns. This pattern will be also used to drive GPIOs
when Radio releases control of GPIOs used to switch antenna.
This property is required. |

Deprecated properties not inherited from the base binding file.
(None)
Properties inherited from the base binding file, which defines common properties that may be set on many nodes. Not all of these may apply to the “nordic,nrf-radio” compatible.
