Set +3dbm power on nrf5340

[mapg]

Hello,

We want to set Tx power of +3dbm i followed the procedure as mentioned in following ticket:

 nRF5340 Radio Tx power 

I set the high voltage in network core main as following:

	nrf_vreqctrl_radio_high_voltage_set(NRF_VREQCTRL, true);
	while(!nrf_vreqctrl_radio_high_voltage_check(NRF_VREQCTRL));
	if (nrf_vreqctrl_radio_high_voltage_check(NRF_VREQCTRL)) {
		LOG_DBG("VREQH configuration success");
	} else {
		LOG_DBG("VREQH configuration failed");
	}

we set value 3 using 

bt_hci_cmd_send_sync(BT_HCI_OP_VS_WRITE_TX_POWER_LEVEL,

buf, &rsp);

While testing with analyzer we get +1.8dbm value.

Can you help us how we can get exact +3dbm?

Regards

Hello mapg,

May I ask two questions please:

- What kind of setup you used to measure the TX Power?

- What board did you use analyze?

Best regards,
