About Gautham

Hello Gautham The problem could be in your  broker setup. I have tested with "test.mosquitto.org" broker. I am able to send data over mqtt successfully. Please find the code below which I have used for testing,   package main; import platforms.xdk110; setup ppWlan : WLAN{ authentication=Personal(psk = "xxx" ); ssid = "xxx"; } setup ppMqtt : MQTT{ transport = ppWlan; url = "mqtt://test.mosquitto.org:1883"; clientId = "ppMQTT"; var publishMsg = topic("hello/world"); } every 100 milliseconds{ print("Publish sensor data\n"); ppMqtt.publishMsg.write("sensor data"); }     Able to connect to Mqtt broker successfully. Please find the test results below,   INFO | Connection to port 'COM12' established INFO | XDK DEVICE 1: [INFO, C:/Users/mvs5cob/XDK-Workspace/EclipseMitaApplication/src-gen/base/ConnectivityWLANPpWlan.c:98] init WlanNetworkConnect succeeded INFO | XDK DEVICE 1: [INFO, C:/Users/mvs5cob/XDK-Workspace/EclipseMitaApplication/src-gen/base/ConnectivityWLANPpWlan.c:113] setting DHCP succeeded INFO | XDK DEVICE 1: [INFO, C:/Users/mvs5cob/XDK-Workspace/EclipseMitaApplication/src-gen/base/ConnectivityWLANPpWlan.c:121] Connecting to personal network: honor 7C INFO | XDK DEVICE 1: [INFO, C:/Users/mvs5cob/XDK-Workspace/EclipseMitaApplication/src-gen/base/ConnectivityWLANPpWlan.c:155] Connected to WLAN.

Hello Gautham There is no template application in XDK Workbench to make the XDK device act as a BLE  scanner. ... View more

Hello Gautham In the screenshot which you provided shows that BLE Event Callback happened. Device was connected and then Device was disconnected. 1. Did you connect and disconnect XDK using BLE scanner mobile application? 2. What was the device name listed during BLE Scan or Advertisement in BLE scanner mobile application ? Is it listed as "BCDS_Virtual_Sensor" ? 3. What android version are you using ? ... View more

Hi Gautham, in BLE based RTLS, beacons only advertize (they pack relevant information like unique IDs into the advertizing packet). No connection (at GAP layer) is established and no true bidirectional communication is established. Anchors can scan for beacons and collect the advertizing information together with some metadata like received signal strength indication (RSSI).  Thus an achor gets information about beacons in its proximity and an indication about how close they are to it. With several anchors distributed in a room you can get some information where your beacon is located. Summarized: Beacon (XDKs) should advertize an ID and anchor (XDK) will scan and collect the IDs together with the RSSI information. Regards, Francisco Llobet      ... View more
