Use Bluetooth in Linux

Today we will introduce how to use Bluetooth through commands in Linux:

Because my laptop does not have bluetooth, I bought a Bluetooth adapter for the USB interface. Run the following command to open it to our Bluetooth device (line 2 ):

Lsusb

RunHciconfigYou can see:

We can see that our Bluetooth device is hci0

RunHcitool DevWe can see the hardware address of our Bluetooth device.

RunHcitoo -- HelpYou can view more commands

Then we activate it:

Sudo hciconfig hci0 up

Note that Bluetooth must be enabled before activation.Otherwise, the following error occurs:

Then we started scanning:

Hcitool Scan

As you can see, I found my mobile phone's bluetooth ~~

Then we will start the connection. The main command used in the connection phase is RFCOMM:

RunRFCOMM -- HelpYou can view usage

First, bind the target bluetooth device:

Sudo RFCOMM bind/dev/rfcomm0 E0: A6: 70: 8c: A3: 02

Note: The above address is the hardware address of the target bluetooth device.

Then we connect it:

Sudo cat>/dev/rfcomm0

This is the target Bluetooth host. In the dialog box that appears, enter the PIN code. Enter either of them. Then, a dialog box is displayed on the host,As long as the input is consistent with the previous one, it can pass verification.. Then we found that my cell phone had displayed a matched tag.

After pairing, We need to delete the binding (otherwise, the device will be prompted to be busy next time). The command is as follows:

Sudo RFCOMM release/dev/rfcomm0

Now we are about to start Bluetooth transmission:

This part is still being studied... Next time add
