How to check presence of Beacon ?

Hi,
it was my fault, if you can read that is sometimes a benefit

In REPEAT-Mode the script writes the RSSI into the user-variable if the tag is present,
in SWITCH-Mode the script writes HOME into the user-variable if the tag is present.

Only for the protocol.

I have the following problem.

The script(s) worked fine on my previous hardware Raspberry Pi 3B.
Now I switched to a Raspberry Pi 3B+ on Berryboot Linux domoticzslave 4.14.83v7-aufs #1 SMP Wed Nov 28 22:52:43 CET 2018 armv7l GNU/Linux

The only way I can have the test_beacon.py have normal output is to open a second putty window and issue an sudo bluetoothctl
with the commands "power on' and 'scan on'
After the 'scan on' the output on the first window is normal, but as soon as I stop the bluetoothctl by 'quit' the output on the first window stops.

Anyone any ideas???

Did you get your setup to work eventually? And could you share your setup perhaps?
I have everything configured like the wiki manual says but the tags I use are only registered by the script when they're in discovery mode. As soon as they go into normal mode the script doesn't see them anymore.
My Pi3B has been configured according to basic needs so no altered bluetooth settings whatsoever.

Nothing. You have 2 Bluetooth-controllers, one onboard and one USB. The script takes the one on HCI0, the onboard one.
The output says it detects the 2 tags you defined in the script just fine. If you have set everything correctly in Domoticz you should see the status of the two tags being updated.

Also, what kind of tags do you use? Mine won't stay on so I'm looking for tags that work with the script.

Thanks for the quick response. Already found more errors. Corrected on HCI 1. There is already a result

It doesn't The script continuously scans for the tag and updates Domoticz accordingly. You get this output because you run the script manually. If you end the script, nothing gets scanned. You can configure the script to be ran as a service so it runs all the time, in the background. You won't see anything on your screen. Check out the logging section of the script to reconfigure it so it only writes warnings/errors to the logfile. If you write debug logging to your logfile grows significantly.

Can you let me know what kind of bluetooth tags you use? I'm dealing with my own problems getting this to work.

I understand all this, if I constantly scan it, will it not download RP3B ???

Variables are already changing, the script is working. There is a concern if he will score RP3b if he constantly scans

Do you mean if the Raspberry will overheat, or overload? No, the script is not powerful enough to do that.

Hey. This is all a translation. I mean, if BLE scanning is going to happen all the time, Can a large processor loop be? I'm working on RP Domoticz

Привет. Это все перевод. Если постоянно будет происходить сканирование BLE, как будет загружаться процессор?

on Pi3b+ give Nodered a chance:

Tnx. for the flow.
Unfortunately it still does not work. There is something wrong with my Bluetooth device on the RPi 3B+ or with libs.
The Answer I get is:

Code: Select all

"Unable to start BLE scan. Adapter state: unknown"

A few post above I explaned what happens on my RPi, but I cannot figure out how to solve it.
And sometimes I get the answer:

Code: Select all

"Unable to start BLE scan. Adapter state: unauthorized"
