Soft reboot crashes

[pmulvey]

This is my boot.py

# test
import os

from machine import UART
uart = UART(0, 115200)
os.dupterm(uart)
print("Serial started")

My main.py

import setup_wifi
print ("In main...011")

And finally setup_wifi.py:

import network
import time

# setup as a station
try:
    wlan = network.WLAN(mode=network.WLAN.STA)
    print("Mode set to STA")
    wlan.connect(ssid="SKYFABCD", auth=(network.WLAN.WPA2, "XXXXXXXX"))

    while not wlan.isconnected():

        time.sleep_ms(50)
    wlan.ifconfig(config=("192.168.0.29", "255.255.255.0", "192.168.0.1",  "192.168.0.1"))
    print ("Booted in STA mode")
except:
    print (str(e))

When I do a CTRL-D for soft reboot it seems to hang on the line:

    wlan = network.WLAN(mode=network.WLAN.STA)

The REPL looks like this (no >>> prompt) and ignores all keys:

>>>
PYB: soft reboot
Serial started

However pressing the reset switch it works fine.
Getting the environment set up with PyCom is a painful process for sure. No doubt the developers have something in the pipeline that takes newbies off the starting line in a more elegant way.

@pmulvey Which version of the firmware are you running. Please look at:

import os
os.uname()

@robert-hh

(sysname='SiPy', nodename='SiPy', release='1.0.0.b1', version='4fb4f54 on 2016-12-15', machine='SiPy with ESP32')

@pmulvey You better should update the firmware. There have been a lot of changes since then. Follow the update procedure https://docs.pycom.io/pycom_esp32/pycom_esp32/getstarted.html#firmware-upgrades

Looking good Robert, behaving OK now, will do more tests. Thank you for you time and advice. - Paul

Looking good Robert, behaving OK now, will do more tests. I must experiment with not connecting to the LAN if it is already connected as this takes a few seconds. Thank you for your time and advice.
