[Raspberry Pi Zero 2 W] I finally bought one and I'm going to try to make it into an access point.

I finally bought it [Raspberry Pi Zero 2 W]

I finally got my hands on a Raspberry Pi Zero 2 W.
I knew it was in short supply, but I didn't think the timing would be so wrong.

Raspberry Pi Zero 2 W

512 MBのRAMと、1 GHz駆動の64 bit Arm Cortex-A53 クアッドコア BCM2710A1ダイを中心としたRaspberry Pi RP3A0 SiPを搭載した、Raspberry Pi Zeroファミリーの最新製品です。

I had been receiving email notifications each time they came in, but I didn't notice or was at work, so I passed them by.
In the meantime, Raspberry Pi5 has been announced.

This one is not yet technically qualified, so we will consider it when the sales timing is determined.

I want to convert my Raspberry Pi Zero 2 W into an access point while still being able to use Wifi in its normal state.

For the time being, we would like to migrate the simple time-lapse camera built on the old ZERO to the ZERO2.

It simply takes a picture every 20 seconds or so with CRON.
All you have to do is turn it on and leave it alone, and you can easily take interesting time-lapse shots.

I have been using wlan0 to connect to ZERO to check the preview or images, but it was inconvenient to re-configure the settings to connect to my home Wifi.

The current configuration of the home Wifi connection will be left as it is, and a virtual Wifi will be set up to be used as an access point.
This way, you can see the preview image when you are out of the house, and when you come back home, you will be connected to the Wifi, making it easy to work with.

We used this site as a reference.

Raspberry Pi WiFiアクセスポイント+クライアント同時使用 - みかんのゆるふわ技術ブログ

前回の記事で、Raspberry PiをWiFiアクセスポイント化してスタンドアロン運用ができるようにしました。 www.mikan-tech.net 実はRaspberry PiはWiFiネットワークに接続しながら自分自身がWiFiアクセスポイントになることができます。 外付けUSB-WiFiなどを用意せず、Raspberry Piの機能だけでできるので便利です😆 この方法で設定してWiFiクライアント機能を使わずスタンドアロン運用もできます。 前回の記事よりわずかに手間が増えますが大差ないので、両対応できるこの記事の方法でセットアップするのも良いでしょう。 今回はWiFiアクセスポイントと…

By the way, since the OS used is Bullseye, the camera is controlled by the libcameta-still command.
I'm still not sure about this area, and I can't use RPi-Cam-Web-Interface yet... I wonder if I'm right...

If you have a legacy camera, using this app is the easiest and best way to use it.

RPi-Cam-Web-Interface - eLinux.org

Set up as soon as possible

If you follow the page you refer to, the work will be completed without any particular problem.
But well, as a note for myself, I will write down the brief flow of the process.

Check your MAC address.

First check your MAC address with the iw command.
If you already know it, this step is not necessary.

1iw dev

Configure Wifi interface to be created at startup

Create a rules file.

1sudo vi /etc/udev/rules.d/99-ap0.rules

Once created, fill in the following information.
Fill in the [MAC address] that you have just confirmed in the MAC address field.

1SUBSYSTEM=="ieee80211", ACTION=="add|change", ATTR{macaddress}=="[MAC address]", KERNEL=="phy0", \
2  RUN+="/sbin/iw phy phy0 interface add ap0 type __ap", \
3  RUN+="/bin/ip link set ap0 address [MAC address]"

Install hostapd and dnsmasq

1sudo apt install hostapd dnsmasq

dnsmasp configuration

Open the configuration file.

1sudo vi /etc/dnsmasq.conf

Add the following to the end of the file

1interface=ap0
2dhcp-range=192.168.249.50,192.168.249.150,255.255.255.0,12h

dhcdcd settings

Open the configuration file.

1sudo vi /etc/dhcpcd.conf

Add the following to the end of the file.

1interface ap0
2static ip_address=192.168.249.1/24
3nohook wpa_supplicant

Oh, and if you want to change your IP, please change it accordingly.
I'm doing it as it is (as long as I can connect).

hostapd configuration

Create a configuration file.

1sudo vi /etc/hostapd/hostapd.conf

The contents of the file should be as follows.

 1ctrl_interface=/var/run/hostapd
 2ctrl_interface_group=0
 3interface=ap0
 4driver=nl80211
 5ssid=Enter SSID of your choice
 6hw_mode=g
 7country_code=JP
 8channel=11
 9ieee80211d=1
10wmm_enabled=0
11macaddr_acl=0
12auth_algs=1
13wpa=2
14wpa_passphrase=Password used for connection
15wpa_key_mgmt=WPA-PSK
16rsn_pairwise=CCMP

Finally, set up the automatic startup.

1sudo systemctl unmask hostapd.service
2sudo systemctl enable hostapd.service

Done.

Wifi Enable

We did not do this process because we had already set up the system with Wifi enabled, but we will enable it if necessary.

Open the configuration file.

1sudo vi /etc/wpa_supplicant/wpa_supplicant.conf

Add the following.

1country=JP

Finally, enable Wifi with the following command.

1sudo rfkill unblock wifi

If you use Rasberry Pi Imager, you can install OS with Wifi enabled, so it is easier.

From industries large and small, to the kitchen table tinkerer, to the classroom coder, we make computing accessible and affordable for everybody.

Once you have set up the last part, reboot and see if your smartphone's Wifi search shows the SSID you have set up.

This is a simple but effective way to set up an access point with your existing Wifi connection.

Pi Zero Case by swintera

Raspberry Pi Zero Case Updated 18/04/2022 - New face (by request). The new face will give you access to the GPIO header. Screwless, snap fit case for Raspberry Pi Zero - tested on the Pi Zero W and Pi Zero WH. Case is modular and comes with an optional spacer shim to allow you to cram more into the case! You need a base, board shim and face to make a complete case. There is access to both USB's and HDMI port as well as SD card slot and CSI camera connector. Currently there are FIVE faces available: Plain Pi Zero Camera TFT (Adafruit Mini PiTFT - 135x240 Color TFT) GPIO Header

This is a case for the Raspberry Pi ZERO. There are no screw holes, and it does not snap into place, so I use this tape to surround the case.

Mini Tripods by walter

Small printable tripod, the folding legs are designed to print in one piece without supports. This is a challenging print and may be difficult with some printers. There are several mounting options, a standard 1/4-20 tripod mount, a hotshoe mount, and a phone mount (the phone mount works best with phones that have a centered audio jack since there's nothing that prevents it from rotating). The ball part of the ballhead is threaded, so try to get the threads aligned before screwing it on to avoid stripping the threads. Warning: Using the audio jack as a tripod mount may damage your phone. Parts List: 1/4-20 x 3/8 Hex Bolt [ebay]* - for attaching the ball head to the tripod legs and for the 1/4-20 mount (for attaching the ballhead, longer bolts can work). M4 x 50mm Hex Bolt [ebay]* - for the ballhead clamp M4 Nut [trimcraftaviationrc] - for the knob audio plug [ebay]* - phone mount only The link to the bolt are for quantities of 100/50 (which is what I ordered), If you only need a few, Bolt Depot may be a good option.

Data for a tripod.
This tripod is quite easy to use, although it requires a 1/4" screw in addition to the one I have output.

I have output the data for ABS, but it can also be used with SLR cameras.
However, there is a weight problem, so this is only if the tripod is light.
