nrf_radio_txpower_t enumeration

[Hiihtaja]

Hello !

I have included to my net core radio driver header

#include <hal/nrf_radio.h>

and expect to use all positive and negative TX power enumerations from nrf_radio_txpower_t enumeration.

But looks like positive values are not defined anywhere

typedef enum

{

#if defined(RADIO_TXPOWER_TXPOWER_Pos8dBm) || defined(__NRFX_DOXYGEN__)

NRF_RADIO_TXPOWER_POS8DBM = RADIO_TXPOWER_TXPOWER_Pos8dBm, /**< 8 dBm. */

#endif

#if defined(RADIO_TXPOWER_TXPOWER_Pos7dBm) || defined(__NRFX_DOXYGEN__)

NRF_RADIO_TXPOWER_POS7DBM = RADIO_TXPOWER_TXPOWER_Pos7dBm, /**< 7 dBm. */

#endif

....

But I think for nRF5340 only 0dM to -40 dbm power is valid

and for have +3dBm I should request VREQCTRL high voltage and set POWER register to 0 dbm

I cook combined driver for nRF52840 and nRF5340 and try to take radio differences in account.

Regards,

Eugene

Is this so ?

Hi,

Yes, this is correct.

Here's a routine to enable this:  nRF5340 Radio Tx power 

 

Kind regards,

Hi !

And for disable; 

NRF_VREQCTRL->VREGRADIO.VREQH = 0;

Or some extra wait loop required ?

No wait loop is needed when disabling. You only need to wait when enabling:
