Yes of course

[eidyn]

If you take the sd card out of the pi and into a pc, then put a different wpa supplicant file on it, will vigibot read and update it successfully on the next boot? Or does this require reflashing the vigimage?

[Mike118]

Yes you can just put a différent wpa supplicant . You can also put multiple wifi config in the file if you wan to switch places frequently... I usually also set up the wifi config that I use when I share internet with my Phone.

[eidyn]

That's exactly what I'm trying to do but having some trouble. If the mobile hotspot (shared connection from phone) isn't available exactly when the pi boots, will it not try to scan and connect again without rebooting?

[Mike118]

If no known wifi are available the pi will try to scan again until it connect a wifi (without rebooting).

[eidyn]

Hmm that's good but doesn't seem to work for me. I will keep trying

[Mike118]

What is your problem ?

[eidyn]

I have 2 networks in wpa supplicant but it will only ever connect to one of them. It won't connect to my mobile hotspot, even when that's the only one available.

[Mike118]

Are you 100% sure that password is correct ? Or that the wpa supplicant file have been correctly written ? The file should be automatically removed from the sd card after the pi boot. Can you confirm that this is correctly happening ? Else it can means a typo in the file name... wpa_supplicant.conf . Do you display file extensions ?

[eidyn]

Yep it is correctly named and now disappeared from boot folder. I know it is read successfully by the pi because it uses it to connect to my home network. It must be something about my mobile network's parameters. I have set the hotspot to 2.4ghz only as I know the pi zero 2 W doesn't support 5ghz. Do you think it could be because there is a space or a special character in the ssid? It's Galaxy S23+ 3338
I'll post the wpa supplicant file when I get a chance

[Mike118]

I don't know why it is not working but if I were you I would rename my mobile hotspot with a simple name and put a simple password and retry...
@Eidyn

[eidyn]

I shall try that, unless you can see anything wrong here? (passwords and ssids redacted of course)
country=GB
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network={
scan_ssid=1
ssid="mobile_ssid"
psk="pass"
id_str="mobile"
priority=1
}

network={
scan_ssid=1
ssid="home_ssid"
psk="pass"
id_str="home"
priority=0
}
Will the priority values mean that it will try to connect to the mobile network first, or the home one?

[eidyn]

It works! Not sure what changed but it works now

How do I get the usb microphone to be recognised?

[eidyn]

I'm sure the exact same microphone worked when it was on my old robot on the default configuration. Could this be because I'm using Pi zero 2 W (usb mic connected through OTG adapter cable)?

[Mike118]

Normally nothing particular need to be done... it may be because of the otg adapter.

[eidyn]

awww ok

[eidyn]

Hmm tried a different adapter and still not working

how does vigibot SLAM work? how does the lidar connect? does it just auto drive around for it to be programmed and learn where walls are? if so, is it possible to get it to work with 2 stories in a house?

[Mike118]

How it works : it works by runnig thank to a great code we made and that you can check the code in the github.
How the lidar connect : serial connection.
Does it auto drive around : the slam include autopilot, but the robot will not drive around autonomously to discover the surronding. You manually drive him or ask him to go to an unknown spot and it will map the world arround him on his way.
2 stories : no unfortunately the current slam is not 3d and will not store 2 maps ... but you can erase the map each time you change... the map building process is fast... and I would bet that right now the robot is not able to climb stairs by itself...
