Einrichtung des Stellar APs

Die hier gezeigten Befehle sind nur in einem internen Entwicklungsbuild verfügbar.

IoT Server Konfiguration auf dem Stellar AP

support@AP-1E:60:/$ cat /tmp/iot-server.conf 
{
	"GenericIoTServer": {
		"ServiceSwitch": "enable",
		"RadioMode": "ble",
		"Host": "192.168.2.134",
		"Port": 1883,
		"Topic": "stellar",
		"ReportingInterval": 5
	}
}

support@AP-1E:60:/$ cat /tmp/ble-config.conf 
{
    "GenericBLE":{
        "ServiceSwitch":"enable"
    }
}

IoT Server starten

(Dies speichert auch die Konfiguration bootfest.)

support@AP-1E:60:/$ ssudo iot-cfg iot-server -f /tmp/iot-server.conf
support@AP-1E:60:/$ /usr/bin/iot-server start ..

support@AP-1E:60:/$ ssudo iot-cfg iot-server show
{
	"GenericIoTServer": {
		"ServiceSwitch": "enable",
		"RadioMode": "",
		"Host": "192.168.2.134",
		"Port": 1883,
		"Topic": "stellar",
		"ReportingInterval": 5
	}
}

support@AP-1E:60:/$ ssudo iot-cfg ble-manage -f /tmp/ble-config.conf 
support@AP-1E:60:/$ {
	"success": true,
	"error": {
		"errorCode": 0,
		"errorMessage": ""
	}
}
/usr/bin/btd start ..
/usr/bin/bt-manager start ..

support@AP-1E:60:/$ ssudo iot-cfg ble-manage show
{
	"GenericBLE": {
		"ServiceSwitch": "enable",
		"ConnectDevList": [
			
		]
	}
}
