This page contains instructions on how to use CLI / SSH command '''UBUS''' for scanning and pairing new Bluetooth devices on RUTX.
==Introduction==
This page contains instructions on how to use '''ubus''' commands in [[CLI]] / SSH to scan and pair '''Bluetooth''' devices on '''RUTX10/11'''.
----

The '''ubus''' command line tool allows to interact with the '''ubusd''' server (with all currently registered services). It's useful for investigating/debugging registered namespaces as well as writing shell scripts. For calling procedures with parameters and returning responses it uses the user-friendly JSON format. Below is an '''Help output''' of this command:

Before you start using ubus commands to control Bluetooth, make sure to enable it first. You can do that in '''Network → Bluetooth → General''' settings. Click '''Enable Bluetooth''' and press '''Save & Apply'''.

*Now login to [[CLI]] or SSH and initialize blesemd, run '''blesemd -D''' command:
...
...
root@Teltonika-RUTX11:~# ubus
root@Teltonika-RUTX11:~# blesemd -D

* Enable Bluetooth in Web UI menu '''Network -> Bluetooth -> General'''. Click ''"Save&Apply"''.
*Run '''scan.start''' command to start Bluetooth scan:
...
...
...
...
* To see scan results, use command '''scan.result''':
*To see scan results, use command '''scan.result''':
...
...
...
...
The scan takes about 30 seconds. The '''"scanning": 1''' output shows us that scan still in progress. You can use '''scan.result''' until '''"scanning": 1'''. You should see similar output:
The scan process takes about 30 seconds. If you can see '''"scanning": 1''' in the output, it means, that scanning is still in progress. After it finishes you should see a similar output:
...
...
"name": "RT_T",
"name": "RT_T",
"rssi": -72,
"rssi": -72,
"address": "FF:CB:FA:6A:23:CB"
"address": "FF:CB:FF:6F:23:FB"
}
}
]
]
...
...
The list of devices always contains '''"rssi"''' and '''"address"''', but '''"name"''' output might be missing:
The list of devices always contains '''"rssi"''' and '''"address"''', but '''"name"''' output might be missing if the device is not supported:
...
...
{
{
"rssi": -42,
"rssi": -42,
"address": "28:21:06:02:72:AD"
"address": "2F:2A:0A:0A:7A:AA"
},
},
{
{
"name": "RT_T",
"name": "RT_T",
"rssi": -77,
"rssi": -77,
"address": "C6:0D:52:5E:35:D7"
"address": "CF:0A:52:5E:35:D7"
}
}
]
]

...
* Device pairing command:
*In order to pair devices use this command:
...
...
ubus call blesem pair '{"address":"FF:CB:FA:6A:23:CB"}'
ubus call blesem pair '{"address":"FF:CC:FF:6A:23:CB"}'
...
...
If the pairing process was successful you should see this output:
...
...
...
...
*To get the statistics from paired devices, use '''stat''' command:
...
...
{
ubus call blesem stat '{"address":"FF:CB:FA:6A:23:CB"}'
...
...
You should see similar output:
...
...
{
{
"success": "successfully requested status",
"success": "successfully requested status",
"model": "3901",
"model": "3901",
"humidity": 20,
"humidity": 20,
"firmware": "23",
"firmware": "23",
.
}
}
