User Manual

Copy the following code to your code.py file on your microcontroller:

Connect to the serial monitor to see the output. It should look something like the following:

Make sure you see the same output! If you don't, check your wiring. Once you've succeeded, continue onto the next

page!

from digitalio import DigitalInOut

from adafruit_esp32spi import adafruit_esp32spi

esp32_cs = DigitalInOut(board.D10)

esp32_ready = DigitalInOut(board.D9)

esp32_reset = DigitalInOut(board.D7)

spi = busio.SPI(board.SCK, board.MOSI, board.MISO)

esp = adafruit_esp32spi.ESP_SPIcontrol(spi, esp32_cs, esp32_ready, esp32_reset)

if esp.status == adafruit_esp32spi.WL_IDLE_STATUS:

print("ESP32 found and in idle mode")

print("Firmware vers.", esp.firmware_version)

print("MAC addr:", [hex(i) for i in esp.MAC_address])

for ap in esp.scan_networks():

print("\t%s\t\tRSSI: %d" % (str(ap['ssid'], 'utf-8'), ap['rssi']))

print("Done!")

If you can read the Firmware and MAC address but fails on scanning SSIDs, check your power supply, you

may be running out of juice to the ESP32 and it's resetting
