Enumeration Type Documentation

nRF905_nextmode_t

enum nRF905_nextmode_t

Available modes after transmission complete.

Enumerator
NRF905_NEXTMODE_STANDBY	Standby mode.
NRF905_NEXTMODE_RX	Receive mode.

nRF905_mode_t

enum nRF905_mode_t

Current radio mode.

Enumerator
NRF905_MODE_POWERDOWN	Power-down mode.
NRF905_MODE_STANDBY	Standby mode.
NRF905_MODE_RX	Receive mode.
NRF905_MODE_TX	Transmit mode.
NRF905_MODE_ACTIVE	Receive or transmit mode (when unable to tell due to the tx pin being unused, hardwired to VCC (TX) or GND (RX))
