Hi guys, could I ask you a question? I hope you can help me...

Can you tell me why there is no "sensorTag" written under "hostBLE4"? in this way I can not detect the data...
Thanks in advance.

Do you have any SensorTag nearby to do BLE advertising?

I have the Sensortag connected via xds110 to the com8

You need to have another CC2650STK running BLE SensorTag example to do BLE advertising so BLE device monitor connecting to current CC2650STK running host_test can scan and connect to it.

Hi guys, could you tell me how to detect the actual data from the sensortag through the Btool app?
I'm following the guide (btool_user_guide TI), in the section "Reading a Characteristic Value by UUID" but I can not understand which values insert in the "characteristic UUID" in the "characteristic read" section in "read / write" ... for example to detect the data of the magnetometer I know that UUID number it's AA81, but why do you give me an error? how should I put it in the Characteristic UUID?

Thanks for answering, but then to detect data on the PC from a single sensorTag (as I do on android) what should I do?

Giuseppe, I merged your threads since they are on the same topic.

I suppose you should have another BLE peripheral device doing advertising otherwise you cannot scan anything.

Hi guys, I bought another sensorTag and I was able to detect the data via the application BLE device monitor but with BTool I still have problems,
I am following the guide mentioned above, I would like to record the data by reading a Characteristic Value by UUID, in particular if I wanted to
detect the data of the magnetometer I know that uuid numer is AA81 but when I insert it I am mistaken, how should I insert it?
The data I find already entered is 00:2A

Try to refer to processors.wiki.ti.com/.../CC2650_SensorTag_User's_Guide

Hi YiKai, I am following the guide processors.wiki.ti.com/.../CC2650_SensorTag_User's_Guide but i can not understand how to trasform a UUID of type AA01 in the configuration of the type --:--.

Is there any pdf that explains this topic?

I tried to read the guide but my problem is in the section "Reading a Characteristic Value by UUID".
I have done all the steps but in the status I have always been "ATTR_NOT_FOUND". I know that (note that the LSB is entered first, and the MSB is entered last) in the “Characteristic UUID) but for example to detect the data of the IR Temperature Sensor , I know that the uuid is AA01 so I insert in the window "Characteristic UUID" 01:AA and give me the error ... what am I doing wrong?

Hi Giuseppe,

Did you see the documentation for GATT_ReadUsingCharUUID() and attReadByTypeReq_t in the BLE Software Developer's Guide? (link: )

bStatus_t GATT_ReadUsingCharUUID ( uint16 connHandle, attReadByTypeReq_t *pReq, uint8
taskId )

Used to read a characteristic value from a server when the client only knows the
characteristic UUID and does not know the handle of the characteristic. The ATT
Read By Type Request is used to perform the sub-procedure. The Attribute Type
is set to the known characteristic UUID and the Starting Handle and Ending
Handle parameters shall be set to the range over which this read is to be
performed. This is typically the handle range for the service in which the
characteristic belongs.

Can you double check that the starting handle and ending handle parameters are set correctly?
