Detect RPi3B+

@mues-lee could you troubleshoot this problem for me?

My guess: This routine doesn't match the new Pi, hence that condition isn't true:

https://github.com/openhab/openhabian/blob/master/functions/helpers.sh#L55
https://github.com/openhab/openhabian/blob/master/functions/wifi.sh#L5

[haroldh]

I checked the helpers.sh part:

This is what my RBP3+ says in /proc/cpuinfo :
Hardware : BCM2835
Revision : a020d3
(my bad, originally I copied from the wrong screen)

As far as I can see, the WiFi part of the logic should include the country selection part.

[ThomDietrich]

Good point. It should and is already available to be copy&paste'ed here: https://github.com/openhab/openhabian/blob/master/build-rpi-raspbian/first-boot.sh#L48

[ThomDietrich]

Revision : a02082

Interestingly this is supposedly still a normal 3B:
https://www.raspberrypi.org/documentation/hardware/raspberrypi/revision-codes/README.md

[mues-lee]

my pi3+ reports the correct
Hardware : BCM2835
Revision : a020d3

we just need to adjust the regex a little bit or add a addional is_piethreeplus function.

I believe just to adjust the regex would be the better solution because otherwise we need to add is_pithreeplus to every place is_pithree is checked for in every file

the following regex should work for pi3b and pi3b+ grep -q "^Revision\s*:\s*[ 123][0-9a-fA-F][0-9a-fA-F][0-9a-fA-F](0d|08)[0-9a-fA-F]$" /proc/cpuinfo

@haroldh are you 100% sure you have a pi3b+?

[haroldh]

@mues-lee yes, I am 100% sure. But I made a mistake copying the revision info from the wrong terminal screen :( (I compared the pi3b and the pi3b+ before I created the information here)
I corrected the information in my original entry.

[mues-lee]

@haroldh ah i see, sorry wasn't meant to sound rude

also since is_pithree is only in three files, i changed my mind and will provide a PR for an extra is_pithreeplus function, just in case we will need the differentiation in future

[haroldh]

@mues-lee no worries, I should have used more emoticons to show that I was not offended :-)

By the way, is there a reason for not using is_pi3plus ? It makes reading a little easier perhaps.

[mues-lee]

the only reason for this is because there was already a is_pithree and didn't wanted to introduce a new naming scheme and yes i agree a is_pi3plus is much easier to read

[Wirsing84]

Awesome! When can one expect for these changes to make it into a new release? Or put otherwise: I have a freshly flashed sd-card I created today with 1.4.1 - but as it seems wifi won't work on my RPi3b+ if I use it. However I can't find the respective files (e.g., functions/helpers.sh), they seem to be compressed in the image. What do I do? Calling for help, I'm new :)

[ThomDietrich]

The addition here is actually unrelated to your issue (I'd bet). Most parts of the openHABian project are not directly included in the provided RPi image but rather part of the openHABian configuration tool, which is shipped with a self-update function. No new update is needed.

but as it seems wifi won't work on my RPi3b+ if I use it

Please open a new issue and describe what you mean with "won't work". Thanks ;)

[Wirsing84]

Oh, I see, then I probably misunderstood. I came here from https://community.openhab.org/t/raspberry-3-b-wifi-on-openhabian/43417/11

I didn't even try the setup process yet as I don't want to run into trouble early on. However I have this brand new RPi3b+ and am seeing these issues arise w/ others... I have a bad feeling about this

[Wirsing84]

Well actually... I have started up the RPi3b+ with 1.4.1 image and ssid and pw set in the config file almost one hour ago. Still no new device in the wifi router... seems like a fail to me?

Ho hum

[ThomDietrich]

Interesting. This routine worked with the RPi3. @mues-lee would you be able to troubleshoot?

@Wirsing84 please go with Ethernet for now. That's better anyhow. After the installation is complete you can still decide to configure and switch over to Wifi.

For all future discussion, please open a new issue! Thanks.
Good luck!

[Wirsing84]

Thank you @ThomDietrich, will do - and would have been next step

[jayloo]

Dear Thom, will you work on this problem soon or should I switch to a former firmware and just go with ethernet....?
