Trying to loop back in to zoneminder but my mind got distracted by Bluetooth again.<\/p>\n\n\n\n
This time trying to get python to talk back and forth with my BLE device.<\/p>\n\n\n\n
Learned a lot today, biggest was that something is wrong when running it from CentOS, and things work right when running from a Raspberry Pi 0 W.<\/p>\n\n\n\n
So if you are following this, do it from a Pi.<\/p>\n\n\n\n
Run the following command from your pi<\/p>\n\n\n\n
gatttool -b ff:ff:c1:aa:bb:cc -I<\/p>\n\n\n\n
Replace the MAC with whatever your MAC is for your device.<\/p>\n\n\n\n
Bah, this is going to take too long here is the code.<\/p>\n\n\n\n
