ESP32-C3 wifi network error

I have 10 QT PY ESP32-C3 boards and I have tried both Micropython and Arduino builds on them.
These boards seem unable to relibly connect or stay connected to Wifi:

Code: Select all

while True:
    try:
        np[0] = (128, 0, 0, 0)
        np.write()
        net.connect(ssid, password)
    except OSError as e:
        np[0] = (128, 0, 0, 0)
        np.write()
        print(e)
    sleep(1)
    if net.isconnected():
        print('Connected')
        np[0] = (0,128, 0, 0)
        np.write()
        break
and what I see is most times is:

Code: Select all

MPY: soft reboot

Sometimes, however (2 boards out of 10 as I type this) I see the board never connect until I re-upload the python file, and that *sometimes* fixes it.

This is a huge problem for me right now as I play whack-a-mole witht hese things falling off the network.

That's really not expected from adafruit boards. Hope they will test the QT PY ESP32-C3 boards and solve this problem.

Code: Select all

try:

except:
    import socket

from time import sleep

esp.osdebug(None)

gc.collect()



print(', '.join(os.uname()))

np = neopixel.NeoPixel(machine.Pin(2), 1)

np[0] = (128, 128, 0, 0)
np.write()
time.sleep(3)
np[0] = (128, 0, 0, 0)
np.write()



ssid = 'LAURENSON'

net = network.WLAN(network.STA_IF)
net.active(False)
sleep(5)
net.active(True)

    net.disconnect()


while True:

        np.write()
        netstat=net.status()
        if netstat==1000:

        np[0] = (0,128, 0, 0)
        np.write()
        break

print(net.ifconfig())


And the output:

For Wifi connections, the question isn't "will the connection drop?" but "when will the connection drop?"

If you need long-term connections, you need to add tests to your code that check the network status and reconnects if necessary before doing anything that will hang or fail without a working network connection.

Understood - I have a watchdog that resets the board if I dont get network traffic for 10 minutes... but let me be clear as to my issue:

I have several (10) Adafruit QT Py ESP32-C3 WiFi Dev Boards and when they don't connect, they don't connect with gusto - in fact the one I have on my bench now NEVER connects. When they disconnect there seems to be a 30% chance that they'll need to be monkeyed with (re-flash, re-upload- disconnect power and futs in general till it comes back). Theyre horrifically unreliable connecting, and the one I have here is 8 feet from an AP.

Code: Select all

import network
import utime
import machine

sta_if = network.WLAN(network.STA_IF)

def connect():
    count = 0

    sta_if.active(True)

    utime.sleep(0.1) #  this could be important, recent posting by robert-hh

 #  seems more reliable to start with a fresh connect()
    if sta_if.isconnected():
        sta_if.disconnect()
        print (f'started in the connected state, but now disconnected')
    else:
        print (f'started in the disconnected state')

    utime.sleep(0.1) #  this could be important

    if not sta_if.isconnected():
        print (f'connecting to hotspot...')
        utime.sleep(0.1)

        try:
#            sta_if.ifconfig((config.WiFi_device, '255.255.255.0', config.gateway, '8.8.8.8'))
#  another recent posting suggest that this should go after the call to sta_if.connect()
            sta_if.connect("LAURENSON", "sekret is here")
        except OSError as error:
            try:
                with open('errors.txt', 'a') as outfile:
                    outfile.write(str(error) + '\n')
            except OSError:
                pass

        while (count < 10):
            count += 1

            if (sta_if.isconnected()):
                count = 0

                print (f'network config: {sta_if.ifconfig()}')

                break

            print (f'. ')
            utime.sleep(1)


    if (count == 10):
        try:
            with open('errors.txt', 'a') as outfile:
                outfile.write('failed to connect after 10 tries' + '\n')
        except Exception as e:
            pass

        disconnect() # or you could get errors
        print (f'machine reset')
        utime.sleep(0.1)

        machine.reset() #  start from scratch


    rssi = sta_if.status('rssi')
    print (f'RSSI =  {rssi} dBm')
    utime.sleep(0.1)

    if ((rssi < -95) or (rssi == 0)):
        print (f'signal level is below -95dBm')
        utime.sleep(0.1)

        disconnect() # or you could get errors
        print (f'machine reset')
        utime.sleep(0.1)

        machine.reset() #  start from scratch


def disconnect():

    sta_if.disconnect()
    sta_if.active(False)
    

connect()
and the result (with known good code, running [for the moment] on 8 other devices) is that this device never connects.

FWIW, some feedback I got:

On my ESP32 _WROOM dev boards I always do two mods:

a 10uF electro across the EN button, which is not relevant to this issue and
a 1000uF LowESR electro on the 3V3 supply, after the regulator.

current pulses during WiFi init can drop the 3V3 enough to cause issues. I noticed several comments about the regulator chips, ie different parts.

C8 22uF won't do much for current peaks.

None of those measures have any obvious connection to the chip's ability to make a Wifi connection. The radios are managed by firmware vwritten in ROM and running in parallel with your code by the built-in operating system.

I don't dispute your experience, but there's no obvious reason why re-uploading working code would change the way the radios work. And since re-uploading doesn't seem to work deterministically, there's a strong chance the actual problem is something else.

It's more likely there's some radio interference at the location where you're working. Try moving the boards to other locations and see if they behave differently there.

I bought 5 more of these, and am seeing the same thing:

I am seeing a lot of malformed packets sent by the ESP32:

There is some sort of bug in the stack, and I need to figure out who/how to fix.... OR the antenna on these units is designed badly...

Attached is a pcap (I am using a test network so passwords in this stuff dont matter):

PCAP: https://github.com/micropython/micropyt ... e.pcap.zip

The ESP and the access point are about 7 feet apart.

By contrast here is the output from a Raspbery Pi Pico running through a connect/disconnect test cycle:

The RasPi has a higher power radio than the ESP32, which would be consistent with a noise/interference issue.

Try repeating the tests at different distances to the WAP, and see if that has any effect on the ESP32's ability to connect.

So, I decided to try rule out the access points/Meraki/Cisco network and set up an old HooToo TripMate Titan router to as to get around any issues with Access Point software, roaming or chipsets. OpenWRT gives us visibility to the details of the connection, as you can see:

Same result.

Hey folks

I have decided to just switch to the Raspberry Pi Pico. I am popping a neopixel on top of the shielding and wiring it in to get the equivalent at a lower cost, but bigger form factor and 100% reliability.

I had to make my own watchdog loop to get better coverage, bu I can be confident in reliability from Raspberry Pi.

Ordered 10 of 'em and will start switching out QT PY ESP32S3s as they do their thing and drop off the network.
