CC2650STK: Software which connect and read data from sensorTag

Part Number: CC2650STK
Other Parts Discussed in Thread: CC2650,

Hello!

I'm new to CC2650 STK and have been tring to develop an app using data from this sensor.

So at current i only have the sensor tag, and i managed to connect it to my laptop via bluetooth. However i cannot detect the device using the BLE device manager. Ive searched a bit and i wonder if a LaunchPad was required to connect the sensorTag to PC and read data from it ? Is there any other software on windows which can read the data from the sensorTag via Bluetooth with no other hardware required?

Thanks in advance

    Hi Yuetao,

    I would use the TI Sensortag app on the apple or google app stores to connect as the getting started guide recommends.

    Hi Nate,

    yeah, the app itself can read data fine, but the push to cloud function on Android apps seems does not work for me. Anyways i was tring to read and process the data from my laptop for app development, so just getting the data on mobile app was not really what i intend to do right now. Unless i could push all the data i received to cloud and read them using laptop.

    I had tried IBM Waston IoT Quick Start, IBM Waston IoT Platform and Azure. None of them worked out for me, As for the Dweet.io, i found it quite confusing so havn't really figure that out.

    Thanks

    Hi Yuetao,

    Can you please clarify what you're trying to do and what the problem you're facing is? 

    From my understanding it sounds like you're trying to connect your laptop with the CC2650STK. This should definitely be possible, but you may not have the software needed on your laptop to process the data from the CC2650STK. You'll likely need to dig into the codebase for the CC2650STK to understand what data is being sent over so your computer can process it accordingly.

    The code flashed to the CC2650STK is meant to function as a demo for what you can do with the device, not necessarily as a starting point for application development. For this, I would recommend flashing the simple_peripheral project to the device and adding functionality from there. This will ensure that you can control what's being sent from the CC2650STK to the computer.

    You can also use BTool connected to a launchpad flashed with the host_test program to monitor the BLE traffic in place of your laptop (as the central device in the connection) for development. This is a tool we recommend often to see the BLE traffic that gets passed between central and peripheral.

    Best,

    Nate

    Hi Nate,

    Thanks again for your detailed reply and sorry for any confuse my word might had caused.

    My current state is just like what you said, i have no idea about how to use the BLE SDK and the CCS ide to get the data from sensortag, i am new to these software, can you please provide any suggestions about how to get started ? Also i found some resources about Simplelink academy, will that be helpful for app development ?

    By the way, i noticed that after i connected the sensortag to my laptop, the connection status will stay at "connected" only for a few seconds then it will turn into "paired" intead of stay connected, then if i wish to connect to sensortag again, I'll have to delete the device and select "add new bluetooth device" to set up a new connection. May i ask that is this normal ?

    Best regards,

    Yuetao
