Description

WiFi.setTxPower() always return +19.5dBm in AP or STA mode

I think there is a typo in the setTxPower() and getTxPower().

Sketch

//in setTxPower() and getTxPower() instead of &&

if (!WiFi.STA.started() && !WiFi.AP.started()) {  //&& is wrong
    log_w("Neither AP or STA has been started");

//should be ||
if (!WiFi.STA.started() || !WiFi.AP.started()) { //|| is correct
    log_w("Neither AP or STA has been started");

Debug Message

return +19.5dBm

"Neither AP or STA has been started" is !(WiFi.STA.started() || WiFi.AP.started())
which in boolean algebra is same as!WiFi.STA.started() && !WiFi.AP.started()

The following code resulted in TX Power: 11.0dBm:

  WiFi.STA.begin();
  if(!WiFi.STA.waitStatusBits(ESP_NETIF_STARTED_BIT, 10000)){
    Serial.println("Failed to start WiFi!");
  }
  WiFi.setTxPower(WIFI_POWER_11dBm);
  int pwr = WiFi.getTxPower();
  Serial.printf("TX Power: %.1fdBm\n", pwr * 0.25);
  WiFi.STA.connect(SSID, PASSWORD);

Thank you me-no-dev. My bad. It looks like there is already the pull request for this issue. I close mine.
