About WIFI¶
You need set WIFI Tx Power to 8.5dBm to use WIFI.
Arduino¶
Use WiFi.setTxPower(WIFI_POWER_8_5dBm) after WiFi.begin() or WiFi.softAP()
WiFi.begin(ssid, password);
WiFi.setTxPower(WIFI_POWER_8_5dBm);
WiFi.softAP(ssid, password);
WiFi.setTxPower(WIFI_POWER_8_5dBm);
simple test:
#include <WiFi.h>
const char* ssid = "yourssid";
const char* password = "yourpasswd";
void setup() {
Serial.begin(115200);
delay(1000);
Serial.println("Connecting...");
WiFi.mode(WIFI_STA);
WiFi.disconnect();
WiFi.begin(ssid, password);
WiFi.setTxPower(WIFI_POWER_8_5dBm);
while (WiFi.status() != WL_CONNECTED){
Serial.print(".");
delay(500);
}
Serial.println("Connected");
Serial.print("IP address: ");
Serial.println(WiFi.localIP());
}
void loop() {
}
MicroPython¶
Use sta_if.config(txpower=8.5) after sta_if.active(True)
def do_connect():
import network
sta_if = network.WLAN(network.STA_IF)
if not sta_if.isconnected():
print('connecting to network...')
sta_if.active(True)
sta_if.config(txpower=8.5)
sta_if.connect('ssid', 'passwd')
while not sta_if.isconnected():
pass
print('network config:', sta_if.ifconfig())
