Python plugin: Bluetooth Beacon Presence Detection

[EddyG]

I tried TCP/IP, but the same problem exists with the 127.0.0.1 address.

[lamouette]

works like a charm, many thanks !

Hi,

For some reason I can't get auto starting to work after a reboot of my pi (with stretch lite).

After a manual start it works flawless.

I hope that someone can help me further with this.

Kind regards, Rob

ble_scanner.sh added as service?
If yes, try to update locally this line in ble_scanner.py to 10+ attempts.
https://github.com/mrin/domoticz-bt-pre ... er.py#L177
By default ~ 25sec (5 attempts * 5sec sleep) for check hci is RUNNING.

@mrinner

I increased the setting to 25 but that doesn't help. I just followed the steps as described. I didn't add any lines to a script. Do I need to?

Thanks for your help!

Can you see which status when service not started:
sudo service ble_scanner status

Also then try to run "hciconfig" without "sudo" and check string "RUNNING" in output.

Hi,

This is the output with "sudo service ble_scanner status":

In the domoticz log I see a lot of lines with:
Calling message handler 'onHeartbeat'.

But the switches are staying off.

Does this info tell you something?

Regards, Rob

[mrinner]

In logs I see several attempts to startup and seems like hci0 was not ready.

In the domoticz log I see a lot of lines with:
Calling message handler 'onHeartbeat'.

in Debug plugin mode this is ok. Plugin checks timeout expiration on each heartbeat.

I will add debug logging in file as option for ble_scanner, maybe on this week.

[mrinner]

@schulpr

Logging in file added. Just git pull updates and uncomment lines in ble_scanner.sh

[schulpr]

@ mrinner,

My knowledge is between noob and hard learning beginner. Can you please help me a bit further? Were do I add this command? In the folder were the plugin is it doesn't work.

Thanks for your help!

Rob

[mrinner]

Go to the plugin folder "bt-presence", then "git pull"
Then "nano ble_scanner.sh" and uncomment lines + check path to log file:

Code: Select all

DAEMON_ARGS="$DAEMON_ARGS --log /home/pi/domoticz/plugins/bt-presence/ble_scanner.log"
DAEMON_ARGS="$DAEMON_ARGS --loglevel debug"

Hi again,

That was easy . I got an error in the update process because it refused to override my config file. I decided to delete the current version and start all over again. Something strange happened, it worked!

So I tried another reboot and it didn't worked anymore. In the log everything seems fine, the process is running correct.

What it doesn't do is switch the switch that is created. I renamed it but that should be the problem I think? This is the content of the log file:

I doesn't grow any further than this.

This is the log when I start the process in terminal:

This turns my switch on and doesn't stop.

I hope this helps to find a solution.

Thanks once more!

Have you try to use a synology as a "scanner" ?

Thanks for this plug in, will try it on serval device (rooted android tv box)

[mrinner]

@schulpr

You can rename created devices as you want, plugin does not relying on name.
First log was immediately after the reboot and log did not grow anymore and "sudo service ble_scanner status" is "active (running)"?
Check what you not run 2 services on the one machine, or some other process maybe use BT.. Discovering can be stopped when hci going down, or bt connecting to some device by other process...

[EddyG]

At the battery check one of my Nut3 came back with only 2 chars.
I had to add/change:

Code: Select all

        bin_value = gatt_output[gatt_output.find("value:") + 6:]
        if len(bin_value) == 2:
             bin_value = bin_value + "00"
        bin_value = bin_value.decode("hex")

[chrispazz]

Which is the correct configuration for having correct battery charge reporting with a NUT2?

Thanks

[chrispazz]

With latest domoticz beta BLE device are no more updating from BLE Scanner....

[chrispazz]

I am the only using this plugin with latest beta?

[mrinner]

@chrispazz

I'm on 3.8805 - my setup works perfect.
Many people have problems with the python plugin system on latest beta...

[chrispazz]

@mrinner

thank you for answering me

I am on 3.8850 and plugin is running ok looking at logs.
It only seems not to update the devices....
