在 NodeMCU ESP8266 中使用 MicroPython 的 RSSI 值

Question

如何使用MicroPython获取连接到我的NodeMCU设备WiFi的WLAN设备的RSSI值？实际上，我尝试了以下代码，但出现错误：

>>> sta_if.ifconfig()         
('192.168.1.103', '255.255.255.0', '192.168.1.1', '192.168.1.1')

>>> sta_if.rssi()        
Traceback (most recent call last):        
  File "<stdin>", line 1, in <module>        
AttributeError: 'WLAN' object has no attribute 'rssi'

不知道如何获取网络的RSSI值

Answer 1

来自WLAN class documentation：

wlan.scan()

Scan for the available wireless networks.

Scanning is only possible on STA interface. Returns list of tuples with the information about WiFi access points:

(ssid, bssid, channel, RSSI, authmode, hidden)
