pi@raspberrypi:~/bt-mqtt-gateway $ sudo systemctl status bt-mqtt-gateway error about bt-mqtt-gateway HOT 17 CLOSED

There is some error with bluetooth adapter. From that logs and info, maybe you try to run 2 instances of the gateway ? One manually with ./gateway.py -d and second one via system service ?

from bt-mqtt-gateway.

Dear Zewelor,
Thank you very much your fast answer.
You are right, I run 2 instances.
How Can I test system service?
Becuse I do not see bt-mqtt-gateway data my nodred

from bt-mqtt-gateway.

I test only ./gateway -d , and if it works I just start system service. It should work then. You can check logs via: journalctl -xef -u bt-mqtt-gateway . And be sure to run only system service then. Maybe there will be something in he logs. Also I would suggest to use mosquitto_sub to monitor all of the mqtt messages, if anything is being sent.

from bt-mqtt-gateway.

Dear zewelor,
I stopped system service and I use onlly ./gateway -d

It woked in morning, but a bit later error message occured

Dear zewelor,
bt-mqtt gateway sometimes wokrs, sometimes do not work. (pi zero w)
I switched to miflora-mqtt daemon isntead. (https://github.com/ThomDietrich/miflora-mqtt-daemon)
miflora-mqtt works well everytime. But I have 3 Xiaomi Mijia LCD sensors also, that I sould prefer your bt-mqtt-gateway.....

from bt-mqtt-gateway.

Hi

For rpi zero w, be sure to use latest bluez ( https://blog.bluetooth.com/bluez-on-raspberry-pi-update ). From what I can see. miflora-mqtt-daemon uses the same miflora lib, but with different bluetooth backend ( https://github.com/ThomDietrich/miflora-mqtt-daemon/blob/master/miflora-mqtt-daemon.py#L220 ), which according to https://github.com/ChristianKuehnel/btlewrap#bluezgatttool-wrapper is less stable, but maybe in older version it works more stable ? I think best way would be to update bluez and try with it. If not I could make git branch with different btlewrap backend to test.

from bt-mqtt-gateway.

Dear zwelor,
I updated my pi zero w to bluez 5.50

I tested bt-mqtt-gateway with
sudo ./gateway.py -d

I tray to subscribe message with mosquitto_sub an other teminal:

(for exapmle: topic mithermometer/corridor/temperature)

But did not receive any mesage .......
Is it correct ?
mosquitto_sub -h 192.168.1.123 -d -t mithermometer/corridor/temperature

from bt-mqtt-gateway.

Try to set client_id in config.yaml . I think that helps sometimes. From that log everything looks fine.

from bt-mqtt-gateway.

Dear zewelor,
how can I set client_id?

This is my configuration.yaml

mqtt:
host: 192.168.1.123
port: 1883
username:
password:
topic_prefix: hostname
client_id: bt-mqtt-gateway
availability_topic: lwt_topic

manager:
topic_subscription:
update_all:
topic: homeassistant/status
payload: online
workers:
mithermometer:
args:
devices:
living_room: 4C:65:A8:D8:AD:A1
#corridor: 4C:65:A8:DC:53:82
topic_prefix: mithermometer
update_interval: 120

It's seems to me
sudo ./gateway.py -d

put data only the terminal, but I can not receive data from MQTT

from bt-mqtt-gateway.

Delete username and password from config. Also for mosquitto_sub try topic -t \# ( listen to all topic ). As you've left topic_prefix, the actual topic is hostname/mithermometer/corridor/temperature , thats why when you filter to only mithermometer/corridor/temperature you don't see anything. Delete topic_prefix also, from the config.

This should print all messages.
mosquitto_sub -h 192.168.1.123 -d -t \#

from bt-mqtt-gateway.

Dear zeweleor,

Thank you very much your patience, and your help.
It works for me at now.

from bt-mqtt-gateway.

Great to hear that. Maybe you can propose some README improvements, to make it easier to setup ?

from bt-mqtt-gateway.

Dear zewelor,

Many user use this topic for to compile Bluez
https://www.domoticz.com/wiki/Mi_Flora_Bluetooth_LE
This use Bluez 5.44 only
Link newest bluez description:
https://www.bluetooth.com/~/media/files/developer/t1804_how%20to%20set%20up%20bluez_lfc_final.ashx?la=en

And suggestion to delete topic_prefix in config.yaml also helped for me
and
mosquitto_sub -h localhost -d -t # command also help for me to test MQTT messages

After such error, you dont need to restart gateway. All errors should be catched, and on another interval time, gateway will make another read. I got usually few per day ( i got 7 devices ). You can just ignore it. Yesterday I've made small update and added "-q" option to skip printing that errors, you can add it in the sevice file to keep logs less verbose.

Thank you

from bt-mqtt-gateway.

Thank you.
I will increase update_interval.
