OpenBeken - Setting Up Static IP for BK7231 IoT Devices with Poor Signal Strength

How can I set a static IP for devices that do not have a good signal?

Thanks.

Hello @jbrande ,
to set the static IP in OpenBeken, first click Config:

Then go to Configure IP:

In Configure IP, enter your desired static IP, your mask, DNS and gateway:


If you are not sure about the Mask, IP, etc, settings, you can check them on your router or on your PC machine (ipconfig command). Futhermore, please make sure that you are setting IP address that is not already reserved, otherwise you'd get an IP conflict.

Alternatively, you can stick to DHCP setting on OpenBeken and just configure a MAC-based address reservation on your DHCP settings of your router.

Let me know if you have any further questions or if something is not clear.[/b]

Wow sorry that i missed that

Hi,
I may have used it wrongly. I did set an IP address 21.21.21.21 and let the rest default.
Now the device is no longer connecting to the network. I think my router would not allow something different from 192.168.0.X
So, I have tried to create the same network (hotspot) from a Linux trying to reach the device and go to the previous setting, but no luck in doing that.
I don't think the device did successfully join the hotspot.

I have tried as well powering down 5 times quickly hoping the OpenBk hotspot shows up again, but no new network showed up.

Do you have any idea on how I could restore the device?

Thank you very much for any help.

The safe mode should just work. I'd say it always worked for me, so far.

Just keep in mind that devices may have large capacitors, so when you do power off, wait maybe even 5 seconds or so.
So, do that 5 times:
- power off
- wait 5+seconds
- power on
- wait 2 or so seconds
Do it 5 or maybe 6 times, and you should get OBK safe mode access point

>>20662501 Tried multiple times in different browsers and it always reverts back to original set DHCP IP. When I access the configure screen I always get this hu.hu.hu.hu on every line.



Any idea on how to fix this issue on a LN882H.

Thank you

It seems that obkStaticIP_t is not currently used (implemented) for LN882H:
https://github.com/openshwprojects/OpenBK7231T_App/blob/main/src/hal/ln882h/hal_wifi_ln882h.c
So it's a pending feature.

>>21212848 Thank you for highlighting this to me. I'll wait for the implementation.

A first approach to implement this is in PR#1342.

I first had to deal with the unknown "%hhu" in printf (generating the IPs like hu.hu.hu.hu) and ssccanf.
Then setting an IP just didn't seem to work, and this turned out to be an implementation of the netif that will always use DHCP.

So as a first try I simply made an extension to the call setting the IP, so afterwards we know IP was statically set and netif handling shall not use DHCP then. Seems simple and straightforward, but maybe there should be a more direct way to disable DHCP on an interface?

So to test it, at the moment you can't simply take the artifacts from the PR but compile it on your own with the patch of SDK file.

@p.kaczmarek2 can I do a PR for the SDK and then make this PR for the APP also including this other PR (to the SDK)?
(I hope you get my question).

Thank you! Please open PR in SDK and I will first apply SDK PR, and then you can try to update submodules on main module PR and we will see if it works.

No problem.
Made PR #17 for OpenLN882H for this.
I introduced a global bool variable for this (g_STA_static_IP) which is set during STA setup (see latest commit on PR #1342)

BTW: your update on pwm_toggler is failing on BL602 (doesn't know "fabs()" - maybe include math.h or use a replacement?)
A very simple idea would be to compare the squares, which will be always positive - but to be honest, I don't know the actual range of the floats, so this might not work if you loose precision needed.

Thanks for including the SDK PR.
I did a new checkout of my (OpenBK7231T_App-)PR and the change in SDK was present.
Compiled a LN882H version and it works like expected

Thank you, merged. I didn't check it myself but I hope you've done it well. @divadiow may check later if he finds time.

Btw, I see we have ESP support PR, would you be able to give it a go?

hmm. it'll give 4 ping responses from the static-set IP (192.168.1.223) but then it switches back to DHCP (192.168.1.163 in my case)



responses here after each reboot

Which version did you try? Maybe it's still built with the old SDK? This would in fact "overwrite" the static settings ...
How does the config page look? Does it show correct IPs or still "hu.hu.hu.hu"?

I just cloned the git and built a new version. and its working for me. Just to be sure, could you try this version?

no hu.hu.hu.hu


flashing posted bin now

happy now on that


I did OTA for both

I see. Looking at the logs, the OpenLN882H SDK is different:

From git run:


From my build:

I did, but sadly don't have some C devices to test - and it fails for ESP32 for me. Maybe the author gives a hint how to fix it (my device indeed have 4MB, which is needed, but only 2MB is configured) or he also adds S2/S3, than I can happily test with them

Ok , thanks, fixed:
https://github.com/openshwprojects/OpenBK7231...mmit/8e5d2e16527e0a2ddb697766d3ec1f92c2d76c04

all good with 1.17.682. After OTA it brought itself up on the preconfigured static IP and is staying there

Good to hear, thanks!

great work!

Well I guess that we now await @kodacy 's feedback. I will ping him to make sure he got notification @kodacy
