Autohotspot function

[Groovylein]

Like in #956 requested, I created a new function in the install script to install a service that checks if a Hotspot is required.

The service checks every 5 minutes if a Hotspot is required. If required it opens up a Hotspot with following credentials:
SSID: phoniebox
Password: PlayItLoud

If connected to the Hotspot you can access the webpage via IP:
10.0.0.5

Now I need testers :)
I was only able to test it on my test environment on a RPi 4

ToDos:

• Merge with buster script
• Create a Wiki Page

Thanks for implementing this. I think many users have been waiting for that feature.

I would suggest to include that as an selectable option in the buster-install-default.sh script.
I would like to avoid two install scripts, which have to be maintained. The install script already causes enough issues ;-)

There is one issue, I am not sure if this script covers it: in the Web UI you can add more than one WiFi network. And the Phoniebox will connect to the available one based on a rank order or importance. Here is a screenshot of that page and some info:
https://github.com/MiczFlor/RPi-Jukebox-RFID/wiki/MANUAL#wifi-settings

In the Hotspot script, the SSID and password are taken from the wpa configuration. In my understanding it is possible that there are more than one ssid / passwd combinations in that file.

1. would that confuse the hotspot script?
2. implementing in the standard install script: if the hotspot conflicts with the WebUI functionality, it should be kept as a separate script?

@Groovylein
thanks for the contribution! I will try it later today.
Because you are also checking if wifi is up or not, possibly you could add your check with ip_address to the script, solving this reported bug: #919

The enable / disable of wifi is here:

RPi-Jukebox-RFID/scripts/playout_controls.sh

Line 547 in e0a0d66

enablewifi)

:) :) :)

Found an issue while running the crontab as root. Fixed it now.

@s-martin you are right. I only created a separate script to test. I will merge it but I think this feature can be installed always. So no option needed.
What do you think @MiczFlor ?

[Groovylein]

1. would that confuse the hotspot script?

Multiple SSIDs and Passwords would not affect the hotspot script as long as they are defined within /etc/wpa_supplicant/wpa_supplicant.conf. A list is created in this case.

2. implementing in the standard install script: if the hotspot conflicts with the WebUI functionality,

It should be kept as a separate script?
I need to check how the WebUI functionality is basically working. In my opinion, I would go with @s-martin and merge it into one script

I only copied the script from the source given in line 1041 😬

I can try adapt this and solve the bug

[Groovylein]

@MiczFlor I've tried the WebUI and the script is working as expected since the WebUI is also using a wpa_supplicant build-in functionality named priority.
The only concern I have is power management which causes some troubles in my setup.
I would merge the scripts together if we decide on installing it as an option or not.

Hi @Groovylein @s-martin
I will merge this for now and do some testing. We should merge this into one install script. I will do that later. Need to keep in mind:

• adding this to the -a option: non-interactive install!!!

[MiczFlor]

@Groovylein
looks like there is a file missing in your pull request:

sudo cp "${sample_configs_dir}"/dhcpcd.conf.buster-default-noHotspot.sample "${dhcpcd_conf}"

[Groovylein]

@MiczFlor what do you mean by "missing"?
I did not delete any files from the sample config folder

[MiczFlor]

You are right. I was wrong. I thought this was part of the new hotspot setup...

[Dodo121188]

I can't see any wifi network of phoniebox in my smartphone , if my phoniebox isn't Connected to home-wlan. Do i have to install this Feature separately?

Thx

[s-martin]

Yes, it's a separate installer script.

https://github.com/MiczFlor/RPi-Jukebox-RFID/blob/develop/scripts/installscripts/buster-install-default-with-autohotspot.sh

[Dodo121188]

Can i install it per one line installer? Do i have to install it from naked Buster Image or can i install it over an existing phoniebox?

Sorry for this beginner questions :)

[Dodo121188]

Sorry i get it, i need help.

I put the Code into a new PhonieboxInstall.conf on home/pi, then make chmod - x, but now i can't start the installer. Can somebody pls help?

[s-martin]

What commands did you execute and what results or error messages did you get?

[Groovylein]

@Dodo121188
What do you mean by "I can't start the installer"? What is the output?
Do you maybe have a screenshot?

Hi @Dodo121188,
the config file is not meant to be called. We need this for the installation script.
You can keep the config file if you modified it.
Please follow the steps:

• install last develop-branch with autohotspot with oneliner
  cd; rm buster-install-*; wget https://raw.githubusercontent.com/MiczFlor/RPi-Jukebox-RFID/develop/scripts/installscripts/buster-install-default-with-autohotspot.sh; chmod +x buster-install-default-with-autohotspot.sh; GIT_BRANCH=develop bash ./buster-install-default-with-autohotspot.sh
  (oneliner)
• reboot

If you experience more problem, please use #956 since this merge is closed
