Verhalten bei der WiFi-Verbindung

Nach dem Wechsel von einer AVM FRITZ!Box 7320 auf eine AVM FRITZ!Box 7520 als DSL-Modem und WiFi Access Point konnte ich ein paar Verhaltensänderungen bei der Verbindungsaufname des FiPy zum WiFi Access Point feststellen.

Im Gegensatz dazu, dass vorher bei jedem Neustart die IP-Adresse wechselte, bleibt sie nun stabil. Möglicherweise ist also der DHCP-Server auf der Box irgendwie besser geworden.
Bisher dauerte die Verbindungsaufname ca. fünf Sekunden, nun klappt es oft schon nach drei Sekunden.
Allerdings klappt die Verbindung zum AP deterministisch nur jedes zweite Mal, also in der Hälfte aller Fälle nicht. Im Anhang kann man die Verläufe im Erfolgsfall und im Fehlerfall nachlesen.

Du schreibst weiter unten, dass Dein (neues) WLAN ohnehin jeden zweiten Verbindungsversuch zum Scheitern verurteilt. Wie unterscheidet sich der Umgang mit dem Fehler “unable to connect” dort wie hier?

Andreas · August 15, 2019, 12:49pm

Scheinbar, leider, ja.

Da wir noch keinen Hintergrund-Dienst zur Überwachung der Verbindung im WiFi-Manager haben, habe ich versucht, die Dinge erst einmal pragmatisch zu verbessern. Ein paar neue commits ^[1] tragen dazu bei, dass a) der Datenlogger an den genannten Stellen nun nicht mehr unmotiviert abstürzt und b) dass zwei Verbindungsversuche unternommen werden weil ja immer einer von beiden deterministisch fehlschlägt.

Die nächsten Ausbaustufen ^[2] kommen dann hoffentlich bald in einer späteren Iteration.

Pragmatischer Service-Thread zur Verbindungsüberwachung oder ggf. ein Ruf zu ensure_connection() kurz vor dem Telemetrie-Akt. Generell wollen wir die bereits separat getrennten Domänen (Sensor vs. Telemetrie) gerne auch beizeiten parallelisieren, um Effizienzgewinne zu erzielen. Momentan wird noch so ziemlich alles sequentiell abgearbeitet. ↩︎

Beobachtungen

In der Praxis sieht das dann so aus wie unten im Log bei Connect to WiFi twice zu sehen. Erst einmal schlägt die Verbindung fehl aber nachdem noch einmal nachgehakt wurde, klappt es erfolgreich. Alles andere als optimal, ist halt aber scheinbar so.

Weitere Nachforschungen

Für die Ursachenforschung könnte man noch ein paarmal den Mond umkreisen. Vermutlich ist es so, dass der halbgare Zustand durch den WiFi-Scan gerettet wird, der zwangsläufig beim zweiten Versuch folgt ^[1].

Einschätzung des Problems

Alles kein Drama. Dass die Verbindung mal nicht klappt, passierte innerhalb der letzten Testreihe nur zwei Mal innerhalb von 18 Stunden Laufzeit im Produktionsmodus (mit Deep Sleep, mit Watchdog, ohne LED-Heartbeat; dafür aber mit Logging und am Strom ohne Batterie) und wird ja nun durch den kleinen Workaround kompensiert.

root@kotori-one:~# cat /home/pi/sermon-workbench-fipy.log | grep Exception

WiFiException: WiFi STA: Unable to connect to "GartenNetzwerk"
WiFiException: WiFi STA: Unable to connect to "GartenNetzwerk"

P.S.: Wenn man das Log genau anschaut, entdeckt man so eine Versionsnummer:

Das kommt aus den ersten Versuchen zu Module freezing for Pycom MicroPython - #5 by Andreas.

… nachdem die auth-mode Informationen gelöscht wurden, die sich zwischenzeitlich im NVRAM gemerkt wurden, damit man im Normalfall keinen Scan benötigt, um das WiFi anzufahren. ↩︎

Andreas · August 15, 2019, 8:59pm

… ist natürlich viel zu unpräzise. Das Schlafintervall lag hier bei 60 Sekunden, zusammen mit den 30 Sekunden Laufzeit ergeben sich über die 18 Stunden Laufzeit also ungefähr 720 Zyklen, von denen wiederum zwei fehlschlugen.

wtf · August 17, 2019, 11:04am

Wie kommt das Terkin denn auf die AP-MAC-Adresse? Ist das ne Info, die nach nem Befehl “verbinde Dich mit $ESSID und $Passwort” generiert wird, oder ist diese “MAC-Adresse” (BSSID präzise zu sein) irgendwie hard-coded und damit Bestandteil des “verbinde Dich”-Befehls?

Also zunächst: Stimmt die denn überhaupt? Ich kann mir schwerlichst vorstellen, dass sowohl die MAC-Adresse des FiPy-Interfaces als auch die Deines WLAN-APs (mutmaßlich AVM Fritzbox) beide vom Vendor Expressif Inc. stammen und direkt nacheinander vergeben wurde (increase of one between ap_mac and sta_mac).

Andreas · August 17, 2019, 2:16pm

Hey,

danke fürs Lesen der Log-Meldungen ^[1].

Alles ist ganz einfach: Beide dort angegebenen MAC-Adressen sind im FiPy einprogrammiert. Die eine ist die designierte MAC-Adresse, die für die WiFi-Netzwerkkarte im STA-Modus benutzt wird (als WiFi-Client), die andere ist die, die im AP-Modus benutzt wird (als WiFi-AP).

Seit einiger Zeit schalten wir pauschal in der Terkin-Firmware beide Modi an, das kann sich zukünftig bestimmt noch einmal ändern, wenn wir den AP-Mode nur unter bestimmten Umständen (auf Zuruf per Knopfdruck oder Steuerbefehl) aktivieren.

Die MAC-Adresse des STA-Interfaces korreliert 1:1 mit der Geräte-ID.

Device id    807d3ac342bc

In der Tat wird für die Vergabe der MAC-Adresse des AP-Interfaces einfach eins auf die MAC-Adresse des STA-Interfaces draufaddiert, ja.

Hilft das weiter, um an dieser Stelle mehr Licht ins Dunkle zu bringen?

You know who you are. ↩︎

Per Parallelize networking subsystem · hiveeyes/terkin-datalogger@22ed127 · GitHub konnten wir die Infrastruktur nun endlich auch in diesem Bereich verbessern.

clemens · August 19, 2019, 8:54am

Magst du mal erklären, was da nun parallel läuft, wir brauchen ja zuerst die Sensordaten um sie dann erst zu schicken. Was bringt das ca. in Sekunden für die runtime?

Andreas · August 19, 2019, 5:01pm

Auf die Gesamtlaufzeit wirkt sich das kaum aus. “Einmal hochfahren und messen” dauert derzeit immer noch um die 30 Sekunden lang.

Wichtig ist an dieser Stelle weiterhin die Stabilität bzw. Robustheit: Mit nun im Hintergrund dauerhaft wirksamen Servicing des WiFi-Moduls ist die Appliance gegenüber Verbindungsstörungen bei der Konnektivität zum Access Point nun auch im Live Mode resilienter.

WiFi connectivity woes

Wir konnten bei einigen Beobachtungen feststellen, dass folgende WiFi-Metriken rausgegeben werden, wenn die Verbindung nicht klappt.

system.wifi.bandwidth                            2
system.wifi.channel                              6

system.wifi.max_tx_power                        78

Wenn die Verbindung klappt, wurden folgende Metriken herausgegeben.

system.wifi.bandwidth                            2
system.wifi.channel                              1

system.wifi.max_tx_power                        78
system.wifi.rssi                               -52

clemens · August 29, 2019, 7:01am

Das Auffälligste ist, dass system.wifi.country sich ändert, ich habe allerdings auch CN bei erfolgreichen Übertragungen (in Deutschland ;-) stehen, s. https://swarm.hiveeyes.org/api/hiveeyes/statista/hds/hive-1/data.txt?from=now-30m&include=system.wifi.bandwidth,system.wifi.channel,system.wifi.country,system.wifi.max_tx_power,system.wifi.rssi

clemens · August 29, 2019, 8:03am

Weil ich gerade in meinen Daten gesehen haben, dass system.wifi.rssi nicht immer übertagen wurde, ein kleiner Zwischenstand von einem System, das ich Anfang der Woche installiert habe:

In den letzten 2 Tagen wurden ca. 1700 Datensätze übertragen, das sind alle 1:40 ein Datensatz. Mit einem konfigurierten measurement interval von 60 Sekunden ergibt sich mit aktiviertem deep sleep eine runtime von 40 Sekunden je cycle.

Bei den DS18B20 gab es zwischen 7 und 9% missings, s.o., bei den system.wifi.rssi gab es 3 % nicht übertragene Werte im Datensatz, was mir bisher noch nicht aufgefallen ist.

Alle anderen Sensoren, sowohl die System-internen als auch Waage und BME hatten keinerlei Ausfälle!

Ergebnisse

Die Datenlogger-Firmware hat mittlerweile eine annehmbare Stabilität und Meßqualität erreicht. Herzlichen Dank an alle, die dabei mitgeholfen haben!

Beobachtungen

Während der Laufzeit traten sporadische Fehler auf, die das Gerät jedoch niemals zum Totalabsturz / Freeze brachten. Zum Beispiel handelte es sich um Dinge wie

Konnektivität fehlt komplett

Falls die Netzwerk-Konnektivität nicht rechtzeitig hergestellt werden konnte, bevor die MCU wieder schlafengelegt wird, schlägt die Telemetrie fehl. Dieser Zustand trat während der gesamten Laufzeit 11 mal ein:

$ cat 2019-09-06_sermon-workbench-fipy.log | grep ERROR | grep EAI_FAIL | wc -l
11

Beispiel

Insgesamt gab es hier 219 mal Probleme.

Status quo

System

Das Gerät “Hiveeyes bEgg mit Bee Observer FiPy Solar” läuft nun seit ca. drei Wochen am Stück unter Labor-/Werkstattbedingungen – hier also noch nicht im Freien.

Meßdaten

Die Meßdaten dazu können bei https://swarm.hiveeyes.org/grafana/d/0CJxruMZz/amo-fipy-workbench?from=20190827T000000&to=20190921T230000 eingesehen werden.

Zwischenfazit

Die Datenlogger-Software scheint nun ausgereift genug zu sein, dass damit nun möglicherweise anständig gearbeitet werden kann.

Mittlerweile sind es knapp anderthalb Monate und alles sieht weiterhin recht gut aus.

Im Zeitraum zwischen dem 2019-09-06 und dem 2019-10-18 musste der Watchdog 22 Mal bemüht werden à la

$ cat 2019-10-18_sermon-workbench-fipy.log | grep 'Reset cause' | grep -v 'DEEPSLEEP'

   12.9637 [terkin.device            ] INFO   : Reset cause and wakeup reason: {'reset_cause': {'code': 2, 'message': 'WDT'}, 'wakeup_reason': {'code': 0, 'message': 'PWRON'}}

Er ist also für einen reibungslosen stabilen Betrieb wie erwartet absolut essentiell.

Immer mal wieder was Neues in dieser Richtung, wenn man mehrere Dinge gleichzeitig tun will und dabei irgendetwas nicht passt oder ordentlich gelöst ist – nur zur Info…

Wohl ein spezieller Fall in dem der zweite I2C-Kanal verwendet wird, der auch die pins verwendet, über die der LoPy mit dem expansion board kommuniziert.
