I try some cheap SD card on ESP8266 (Micropython) appear error below when via spi = SPI(1, sck = Pin(14), mosi = Pin(13), miso = Pin(12)) sd = sdcard.SDCard(spi, Pin(15)) uos.mount(sd, '/sd') Traceback (most recent call last): File "<stdin>", line 1, in <module> File "sdcard.py", line 234, in readbl...

How to list the SSID hidden APs ?

Thanks.
