    TinyB example partially works for Java 8 on Edison, need help!




      I have a project that needs to connect to an array of Bluetooth LE sensors. I wrote the sensors myself and they are compliant with the Environmental Sensing and Battery Service profiles. I can use my Android BLE apps to connect to the sensors and utilize them just great. In fact they work better than expected. Now I'm trying to get my app to run on the Edison with all the latest software update/upgraded with opkg.


      I am trying to run a modified version of the HelloTinyB example. When I run it I get the following output;


      Listening for transport dt_socket at address: 8005

      The discovery started: true

      Address = E2:E4:BD:03:41:03 Name = DSLT-TMP Connected = false

      Address = F0:79:59:2B:93:40 Name = Snarf Connected = false

      Error: GDBus.Error:org.bluez.Error.InProgress: Operation already in progress

      Found device: Address = E2:E4:BD:03:41:03 Name = DSLT-TMP Connected = false

      Sensor with the provided address connected

      Services exposed by device:

      Device Addr: E2:E4:BD:03:41:03

      Device: DSLT-TMP -> 00001530-1212-efde-1523-785feabcd123

      Device: DSLT-TMP -> 00001800-0000-1000-8000-00805f9b34fb

      Device: DSLT-TMP -> 00001801-0000-1000-8000-00805f9b34fb

      Device: DSLT-TMP -> 0000180a-0000-1000-8000-00805f9b34fb

      Device: DSLT-TMP -> 0000180f-0000-1000-8000-00805f9b34fb

      Device: DSLT-TMP -> 0000181a-0000-1000-8000-00805f9b34fb

      Device: DSLT-TMP -> 6e400001-b5a3-f393-e0a9-e50e24dcca9e

      Device: DSLT-TMP -> ee0c2080-8786-40ba-ab96-99b91ac981d8

      Services > ? 0


      So the Device: DSTL-TMP show the UUIDs the devices is advertising BUT when the "bluetoothServices = device.getServices();" is executed it brings back a zero length list forever. Its in a loop with a 4 second sleep.


      When you print the UUIDs you can clear see the UUIDs for the two services I want to connect to;


      UUID: Battery Service (0000180f-0000-1000-8000-00805f9b34fb)

      UUID: Environmental Sensing  (0000181a-0000-1000-8000-00805f9b34fb)


      In fact, the above UUIDs I got from the bluetoothctl tool so I'm at a loss now. If anyone could help it would be great. Thanks!
