CAMEYAMASAN version 1

CAMEYAMASAN(version 1) is Time-lapse camera using M5Stack Timer Camera X and Raspberry Pi.

Set Timer Camera X and Raspberry Pi on the same Wi-Fi network, start a web server on Timer Camera X, and then use HTTP requests from Raspberry Pi to get camera images.

A. How to use Raspberry Pi as a Wi-Fi access point (Case of RTL8188EUS USB dongle)

1. Start Raspberry Pi and Login by SSH

2. Install RTL8188EUS dongle driver

   • http://downloads.fars-robotics.net/wifi-drivers/8188eu-drivers/
   • Example of raspberry pi zero w http://downloads.fars-robotics.net/wifi-drivers/8188eu-drivers/8188eu-5.4.83-1379.tar.gz

   $ cd /home/pi
   $ wget http://downloads.fars-robotics.net/wifi-drivers/8188eu-drivers/8188eu-5.4.83-1379.tar.gz
   $ tar -xvzf 8188eu-5.4.83-1379.tar.gz
   $ chmod +x ./install.sh
   $ ./install.sh

3. $ iwconfig to see if wlan1 exists

4. Install

$ sudo apt update
$ sudo apt upgrade -y
$ sudo apt install hostapd dnsmasq

5. Edit /etc/dhcpcd.conf

$ sudo vim /etc/dhcpcd.conf

add below

interface wlan1
 static ip_address=192.168.2.1/24
 static routers=192.168.2.1
 static domain_name_servers=192.168.2.1
 static broadcast 192.168.2.255

6. Edit ./py/variables.py

$ vim ./py/variables.py.

Write ssid and wpa_passphrase(ps) in py/variables.py.

7. Edit /etc/hostapd/hostapd.conf

$ sudo vim /etc/hostapd/hostapd.conf

Write ssid and wpa_passphrase(ps) from py/variables.py.

interface=<wlan1>
driver=nl80211
ssid=MY-RP-SERVER
hw_mode=g
#channel=11
channel=3
wmm_enabled=0
macaddr_acl=0
auth_algs=1
ieee80211n=1
wpa=2
wpa_key_mgmt=WPA-PSK
wpa_pairwise=CCMP
wpa_passphrase=Password

8. Edit dnsmsq

$ sudo vim /etc/dnsmasq.conf

interface=wlan1
dhcp-range=192.168.2.2,192.168.2.100,255.255.255.0,24h

9. Edit syctl.conf

$ sudo vim /etc/sysctl.conf

Uncomment the next line to enable packet forwarding for IPv4.

net.ipv4.ip_forward=1

$ sudo iptables -t nat -A POSTROUTING -o wlan0 -j MASQUERADE $ sudo sh -c "echo 1 > /proc/sys/net/ipv4/ip_forward"

10. unmask settings

$ sudo systemctl stop hostapd
$ sudo systemctl unmask hostapd
($ sudo hostapd /etc/hostapd/hostapd.conf)
$ sudo systemctl enable hostapd
$ sudo systemctl start hostapd
$ sudo systemctl start dnsmasq

11. Check Wi-Fi Access Point

# Start server for confirmation
$ python3 -m http.server 3000

Connect MY-RP-SERVER from PC or Smartphone. Open 192.168.2.1:3000 in Browser.

12. Add below to /etc/rc.local at before exit 0 $ sudo vim /etc/rc.local

iptables -t nat -A POSTROUTING -o wlan0 -j MASQUERADE
sh -c "iptables-save > /etc/iptables.ipv4.nat"

service dnsmasq stop
sleep 8
service dnsmasq start
iptables-restore < /etc/iptables.ipv4.nat
sleep 3
service hostapd restart

13. check connecting internet
