A tl;dr test code.py (assuming ESP32 is behaving): import board
import time
from digitalio import DigitalInOut
from adafruit_esp32spi import adafruit_esp32spi
from secrets import secrets
spi = board.SPI()
try: # PyPortal, etc.
esp32_cs = DigitalInOut(board.ESP_CS)
esp32_ready = DigitalInOut(board.ESP_BUSY)
esp32_reset = DigitalInOut(board.ESP_RESET)
except AttributeError: # Airlift FeatherWing & Bitsy Add-On compatible
esp32_cs = DigitalInOut(board.D13)
esp32_ready = DigitalInOut(board.D11)
esp32_reset = DigitalInOut(board.D12)
esp = adafruit_esp32spi.ESP_SPIcontrol(spi, esp32_cs, esp32_ready, esp32_reset)
print('Connect... BSSID RSSI SSID')
esp.connect_AP(secrets['ssid'], secrets['password'])
# NEW: bssid
print('{5:02X}:{4:02X}:{3:02X}:{2:02X}:{1:02X}:{0:02X}'.format(*esp.bssid), end='')
print(' {: 4d} {:s}'.format(esp.rssi, str(esp.ssid, 'utf-8')), end='')
print(' ping=%dms (LAN)' % esp.ping(esp.network_data['gateway']))
print()
while True:
print('Scanning... BSSID Ch RSSI SSID')
for ap in esp.scan_networks():
# NEW: bssid, channel
print('{5:02X}:{4:02X}:{3:02X}:{2:02X}:{1:02X}:{0:02X}'.format(*ap['bssid']), end='')
print(' {: 3d} {: 4d} {:s}'.format(ap['channel'], ap['rssi'], str(ap['ssid'], 'utf-8')))
print()
time.sleep(10)A more robust code.py is here. Actual output data matches data from macos |

@anecdata This are very useful methods - thanks for exposing it within ESP32SPI. I successfully tested against your provided example code and verified against I also tested against ESP32SPI simpletest since it runs a wifi scan to ensure it still works as-expected: |

Changes to esp32spi.py to address #74
I'd appreciate @adafruit/circuitpythonlibrarians (don't seem to be able to tag the team) code review (and test). There were good examples in the code to work from, but first time interpreting C types into CP.
Tested on a variety of combinations of M4 and ESP32 hardware. I'll post a test code.py and sample output in the comments.
P.S. BSSID, like MAC, comes in with the first octet in the 6th byte. Depending on the resolution of #66 a helper function could be added or it could be left to examples to illustrate this.
