No wifi connection v0.0.7+

[flippest]

Upgraded from v0.0.2 to v0.0.7 and wifi no longer connects. Tested several configurations of 2.4Ghz vs 5Ghz to no avail. Downgraded to v0.0.2 to confirm wifi hardware functionality and was able to connect. Flashing back to v0.0.7 as well as upgrading to v0.0.8 wifi connectivity issue persists

MPY: soft reboot

Yep, I'm also getting similar errors on v0.0.8.

Thanks both for raising this. I am not sure of the exact issue that would cause this yet, but I have been experiencing WiFi issues that were caused by the reading of the battery voltage, particularly when on USB power.

If you are still interested in diagnosing this, could you try commenting out these lines from enviro/__init__.py

old_state = Pin(WIFI_CS_PIN).value()
Pin(WIFI_CS_PIN, Pin.OUT, value=True)
sample_count = 10
battery_voltage = 0
for i in range(0, sample_count):
  battery_voltage += (ADC(29).read_u16() * 3.3 / 65535) * 3
battery_voltage /= sample_count
battery_voltage = round(battery_voltage, 3)
Pin(WIFI_CS_PIN).value(old_state)

Then add a line like battery_voltage = 0.0 so that later code still works

There is a new release that temporarily fixes this by disabling battery monitoring: https://github.com/pimoroni/enviro/releases/tag/v0.0.9 Please could you update and retest?
