==ubus commands==
This section contains instructions on how to use <b>ubus commands</b> in order scan and pair with Bluetooth devices.
The <i>ubus</i> [[Command Line Interfaces|command line]] tool provides the possibility to interact with the <i>ubusd</i> server (with all currently registered services). It uses the JSON format for calling procedures with parameters and returning responses.
Before you start using ubus commands to control Bluetooth, make sure that Bluetooth is turned on in the [[#General_Settings|General Settings]] section.
----
You must first initialize <i>blesemd</i>. You can do that by executing <b><i>blesemd -D</i></b> command. The output should look similar to this:
...
root@Teltonika-{{{name}}}:~# <b>blesemd -D</b>

----
Run <b><i>scan.start</b></i> to start Bluetooth scan:
...
ubus call blesem <b>scan.start</b>
...
To see scan results, use command <b><i>scan.result</b></i>:
...
ubus call blesem <b>scan.result</b>
...
----
The scan process takes about 30 seconds. If you see <b><i>"scanning": 1</b></i> in the output it means that scanning is still in progress. Once the scanning has finished, the <i>scan.result</i> output should look similar to this:
...
{
<b>"scanning": 0,</b>
"devices": [
{
"name": "RT_T",
"rssi": -72,
"address": "FF:CB:FF:6F:23:FB"
}
]
}
...
The list of device parameters will always contain"rssi" and "address", while the existence of "name" will depend on whether the paired Bluetooth supports it or not.
...
{
"scanning": 0,
"devices": [
{
"rssi": -42,
"address": "2F:2A:0A:0A:7A:AA"
},
{
"name": "RT_T",
"rssi": -77,
"address": "CF:0A:52:5E:35:D7"
}
]
}
...
----
In order to pair devices use the <b><i>pair</b></i> command and specify the device's MAC address:
...
ubus call blesem <b>pair</b> '{<b>"address":"FF:CC:FF:6A:23:CB"</b>}'
...
If the pairing process was successful you should see an output similar to this:
...
{
"success": "device successfully paired"
}
...
---
To get the statistics from paired devices, use the <b><i>stat</b></i> command and specify the device's MAC address:
...
ubus call blesem <b>stat</b> '{<b>"address":"FF:CB:FA:6A:23:CB"</b>}'
...
The output should look similar to this:
...
{
"success": "successfully requested status",
"model": "3901",
"battery": 98,
"temperature": "20.34",
"humidity": 20,
"firmware": "23",
.
}
