nRF5340 Radio Tx power

[mingjkl]

I want to increase the transmit power of nRF5340 to 3dBm, I have added the following code to achieve this function, may I do this correctly.

void radio_power_enhance(void)
{
	NRF_VREQCTRL->VREGRADIO.VREQH = 1;
	while(!NRF_VREQCTRL->VREGRADIO.VREQHREADY);
	printk("VREQHREADY!\r\n");
	printk("VREQH %d, ready %d",NRF_VREQCTRL->VREGRADIO.VREQH, NRF_VREQCTRL->VREGRADIO.VREQHREADY);
}

Hi,

 

Yes, your routine will request the VREQH, to allow each radio TX mode to be offset with 3 dB (ie. setting NRF_RADIO->TXPOWER=0dBm becomes +3dBm output).

 

Kind regards,

Håkon

What header files do I have to include to use these commands ?
