Hi all,
Wanna try to get this working and it's kind of OK with "mini NUT".
Service is started :
Code: Select all
[Unit]
Description=Beaconing Service
After=multi-user.target
[Service]
User=root
Type=idle
ExecStart=/home/pi/beaconservice.py
Restart=always
RestartSec=5
[Install]
WantedBy=multi-user.target
I changed the script a little bit to use Python 3 and I'm using DZ switch only and no DZ variable :

# Configure your Beacons in the TAG_DATA table with : [Name,MacAddress,Timeout,0,idx,mode]

# 0 : used by the script (will keep the time of the last broadcast)

Both TAGS were at home today...
Since i'm also using l2ping to ping the Bluetooth of my phone and i can't use l2ping to ping "mini NUT", is anyone knowing a bluetooth beacon which responds to l2ping command ?
Thank you
