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.
Steps to use ubus for blesem service on RUTX:
- Enable Bluetooth in WebUI menu Network -> Bluetooth -> General. Click "Save&Apply".
- Login using CLI and run scan.start command to start Bluetooth scan:
... ubus call blesem scan.start ...
- To see scan results, use command scan.result:
... ubus call blesem scan.result ...
The scan takes about 30 seconds. The "scanning": 1 output shows us that scan still in progress. After it finishes you should see a similar output:
... { "scanning": 0, "devices": [ { "name": "RT_T", "rssi": -72, "address": "FF:CB:FA:6A:23:CB" } ] } ...
The list of devices always contains "rssi" and "address", but "name" output might be missing:
... { "scanning": 0, "devices": [ { "rssi": -42, "address": "28:21:06:02:72:AD" }, { "name": "RT_T", "rssi": -77, "address": "C6:0D:52:5E:35:D7" } ] } ...
- Device pairing command:
... ubus call blesem pair '{"address":"FF:CB:FA:6A:23:CB"}' ...
On success pairing you should see output:
... { "success": "device successfully paired" } ...
On success pairing new device info will be written in blesem service config:
... config device option address "FF:CB:FA:6A:23:CB" ...
- Device unpairing command:
... ubus call blesem unpair '{"address":"FF:CB:FA:6A:23:CB"}' ...
- To get statistic from paired devices, use stat command:
... ubus call blesem stat '{"address":"FF:CB:FA:6A:23:CB"}' ...
You should see output:
... { "success": "successfully requested status", "model": "3901", "battery": 98, "temperature": "20.34", "humidity": 20, "firmware": "23", . } ...
