I followed https://hacks.mozilla.org/2017/02/headless-raspberry-pi-configuration-over-bluetooth/
I see nothing on the bluetooth devices in my cellphone or computer. Here's the output of my raspberry pi:
pi@raspberrypi:~ $ sudo service bluetooth status
● bluetooth.service - Bluetooth service
Loaded: loaded (/lib/systemd/system/bluetooth.service; enabled; vendor preset: enabled)

I also tried running rfcomm on the terminal but it returns immediately.
I also tried:
pi@raspberrypi:~ $ /usr/bin/rfcomm watch hci0 1 getty rfcomm0 115200 vt100 -a pi
Waiting for connection on channel 1
but I still see nothing on the bluetooth devices. I waited 10 minutes and nothing appears.
UPDATE:
I found a video which tells me to add a -C in front of the bluetooth service and also do this:
sudo bluetoothctl
power on
pairable on
discoverable on
agent on
default-agent trust
Now I can connect to the raspberry pi but it stays connected for 1 second and then disconnects
UPDATE:
I tried pairing from my PC to the raspberry, and then from the raspberyr to PC. Both ways it pairs, then the two paires devices disconnect. It only connect for 2 seconds.
