Jetson TX2 Bluetooth device management

I bought the Jetson tx2 just because it has the bluethoot in the hardware …
and CUDA c … I want technical assistance on how to manage it from cuda c …
I want it from you … I do not want and time to devote to the Linux world …
is a month that I have it … and yet I have not done anything …
I just hope it has not become obsolete …
I hope for your help … I am an elderly person …

Hi umbertobqv7e, which kind of Bluetooth device are you trying to connect to your Jetson TX2? Jetson’s Bluetooth adapter supports Linux-standard BlueZ stack in Ubuntu. Although you can use libbluetooth to interface from C, it is easier and more typically done from the GUI or command line.
Try running these from terminal to verify that your Jetson’s Bluetooth adapter is functioning:

$ sudo apt-get install libbluetooth-dev
$ sudo rfkill unblock bluetooth
$ hcitool dev
# bluetooth adapter info should now be printed out

For more commands to configure Bluetooth device connections, man hcitool.

hi dusty_nv,thank you for your reply…my device is HUAWEY P10 lite…
I gave your commands to the terminal and the output is this:
Devices:
hci0 00:04:4B:8D:18:4B
it’s correct?

Yes, this is expected. Here’s further info on pairing with Bluetooth devices through the Ubuntu UI:

This is a smartphone, it is unclear how two host adapters would connect. Typically a host adapter like on the Jetson or smartphone would connect to a device like a wireless keyboard, controller, speaker, microphone, ect.

@dusty_nv - I was able to get a smartphone (Oneplus 5) to communicate over bluetooth with the TX2.

@umbertobqv7e have you ensured that the Jetson TX2 bluetooth is discoverable?

I needed to do the following to see the device from my phone:

nvidia@jetson-1:~$ bluetoothctl 
discoverable on

I left the jetson tx2 … she died …
I do not want to deal with NVIDIA anymore …
I lost 700 euros … but I do not care …
NVIDIA lost more … me …
I was having fun with CUDA …
