Hi all,

I'm developing a bundle which wants to integrate with a TI SensorTag via BLE, but I am having the following problem:

the log file:

In log file after executing "connect" command it also executing "exit" command. I don't know why it is executing "exit".

When I am trying from the termnal it is connecting without anyerror

Hi,

the example described in the documentation, indeed, creates a connection to the SensorTag, reads the sensor values and closes it.
Take a look on the updated example here [1]. In this case, the bundle keeps the connection open.

Best,
Pier

Hi Pier,
After connecting it is not showing any readings(like temperature, humidity etc.). In the github link it is not entering the if-loop at line no:434
At line 420==>m_connected = myTiSensorTag.connect(); It is returning false.
In TiSensorTag.java https://github.com/eclipse/kura/blob/develop/kura/examples/org.eclipse.kura.example.ble.tisensortag/src/main/java/org/eclipse/kura/example/ble/tisensortag/TiSensorTag.java file, in connect() function, at line 67==>connected = m_bluetoothGatt.connect(); it is trying to connect but it is also returning false.After that at line 78 it disconnecting with executing "exit" command.
I don't know why it's not connecting. With terminal it is connecting and I can read temperature values also.
Please help me.
Regards
Tejram.

Hi,

on which device are you running the example?
You could set the log level to debug on the org.eclipse.kura.linux.bluetooth package and see on kura.log the gatttool output.

Hi Tejram,

May you show us your BluetoothLe.java file?

Hey all,
same problem here.
I used the BLE Java File from:

Is the name of the SensorTag important? I changed it days ago with the iOS App into "CC2650"

Hi,

the name of the SensorTag is used only to select which type of device the bundle is trying to connect to. This is due to the fact that the old SensorTag has different sensors and register respect to the new one (CC2650).

Which SensorTag are you using? The new (CC2650) or the old one (CC2541)?

My suggestion is to set the log level to debug and take a look on kura.log.
To do this, edit the /opt/eclipse/kura/kura/log4j.properties file and add the following files:
log4j.logger.org.eclipse.kura.example.ble.tisensortag=DEBUG
log4j.logger.org.eclipse.kura.linux.bluetooth=DEBUG

Thanks for your reply. I logged also the debug, see below.

"Reads data from all the sensors onboard and writes the values in the log file" from https://eclipse.github.io/kura/doc/bluetooth-le-example.html#bundle_sensortag_1

But it doenst log Smile

then it starts over and over again...

my settings on the Kura BLE Package: see png attached
I dont want to publish the data to a cloud right now, thats what I filled that "needed" part with anything...


Thanks!

Hi,

what device and what version of Bluez are you using?
Did you try via command line?

Raspberry Pi Model B+, Bluez Version 5.23
Via cmd line and the Gatt table from the TI Website I can read out the single date from the sensor...
I dunno why it doenst work properly...

In my opinion the made sample by eclipse is probably a bit messy. But the single code lines like enable temp. sensor etc should be right... i checked some of them-

Does anybody got the system work? Raspi + SensorTag !? Would be nice to hear that i am not the only 1 with those problems Razz

Hi,
I tested the bundle with a RPi2, Bluez 5.23 and both SensorTags.
The bundle worked with my configuration, but I'll take a look on it trying to reproduce your situation.
