Es gibt einen neuen Pi Zero W! Es wurde auch Zeit, dass sie das endlich machen, denn ein günstiges, wenig strom verbrauchendes Pi für alle Projekte, die ein volles Linux benötigen, ist sehr nützlich. Nur leider war der kleine Pi mit seinem einen alten Kern schon ziemlich müde. Das fixt das neue Zero 2 W, indem es sozusagen ein pi3 im kleinen Formfaktor ist.  Hardware : BCM2835 Revision : 902120 Serial : 00000000decafbad Model : Raspberry Pi Zero 2 Rev 1.0 Leider kommt es wie das alte Zero W nur mit 512 MB RAM, aber das kann man dank den vier schönen ARMv7-Kernen immerhin etwas durch den Einsatz von mit z-ram kompensieren. Und das ist auch das erste, was ich mit dem kleinen Pi mache. Das Script von hier https://github.com/novaspirit/rpi_zram ist da zeitsparend nützlich. Das Ergebnis ist schneller Swap, ohne SD-Karten zu killen pi@zero2w:~ $ cat /proc/swaps Filename Type Size Used Priority /dev/zram0 partition 438248 0 5 /dev/zram1 partition 438248 0 5 /dev/zram2 partition 438248 0 5 /dev/zram3 partition 438248 0 5 Apropos zeitsparend, das raspberry pi OS image von der offiziellen Website ist von Mai, da muss man schon einige Zeit auf die apt upgrade Aktion warten. Die könnten mal wieder ein neues Image releasen...  Mit dem neue Pi und seiner Leistung bin ich sehr zufrieden, nur verlor er gelegentlich die WLAN-Verbindung, obwohl er nicht mal einen Meter vom Accesspoint weg liegt. Im Eventlog stehen dann viele Fehler zum broadcom wlan Treiber, dass der reconnect fehlschlägt. > Nov 7 06:59:39 zero2w kernel: [128286.642653] ieee80211 phy0: brcmf_run_escan: error (-110) Nov 7 06:59:39 zero2w kernel: [128286.642676] ieee80211 phy0: brcmf_cfg80211_scan: scan error (-110) Nov 7 06:59:39 zero2w kernel: [128286.643556] ieee80211 phy0: brcmf_cfg80211_escan_handler: scan not ready, bsscfgidx=0 Nov 7 06:59:39 zero2w kernel: [128286.643572] ieee80211 phy0: brcmf_fweh_event_worker: event handler failed (69) Das kenne ich leider schon von den alten Zeroes. Aber auch hier gibt es eine Abhilfe von c't: die [bluetooth shell](https://www.heise.de/ratgeber/Bluetooth-Shell-fuer-Raspberry-Pi-und-Raspi-Zero-W-4265284.html). Damit kann man via Bluetooth rfcomm ein mgetty erreichen, wenn die WLAN-Connectivity wegbricht. ``` wget "ftp://ftp.heise.de/pub/ct/listings/1901-186.tgz" tar xvfz 1901-186.tgz apt install mgetty dpkg -i btlogind*.deb ``` Da heise das als Notfall-Lösung per Steckbrücke geplant hat, ich die BT Konsole aber immer aktiv haben möchte, stelle ich das um: ``` systemctl disable btlogin systemctl stop btlogin systemctl enable btconsole systemctl start btconsole ``` Als letztes möchte ich noch rausfinden, ob der schöne Adapter von [zerostem.io](https://www.reichelt.de/de/de/raspberry-pi-zero-adapter-von-kontakt-auf-usb-rpiz-usb-adapter-p291515.html) noch funktioniert, mit dem man das zero zum USB-Stick Computer umbauen kann. Bis zum nächsten freenerding...

Pi3 mit 2W... Ich liebe IT. :-) Danke für die Information, das ist dann auch der Einstieg für mich nach all den Jahren Theorie und Ausloten, wohin ich eigentlich will.

pi 2W ist auch besser als 2G oder 3G oder sonstwas G+ wie hier in Söders Bavaria
