Dear experts,

I understand that CC2541 is now obsolete and there are new chipsets like CC2650. But, I will not be able to buy the new kits because of un-availability of budget. I possess the CC2541DK-Sensor Rev 1.4.1. Can you please send me the link for the android application for monitoring different sensors (Gyroscope, humidity, temperetaure, accelerometer etc)? I can only find for CC2640. Please help.

Thanks & regards
Sandeep Suresh.

    Hello Sandeep,

    Just to clarify, the CC2541 and CC2540 wireless MCUs are not obsolete and still active in the TI catalog. The CC2541 SensorTag IoT kit is no longer available as this has been replaced by the CC2650STK.

    Did you try using the SensorTag android app with your CC2541 SensorTag?

    Best wishes

    Hello JXS,

    Thanks for the quick response. I have 2 CC2541-SensorTag units and tested as follows:-

    1. First CC2541-Sensor Tag:- Installed BLE-CC254x-1.4.2.2.exe and the software projects etc. Installed IAR Embedded workbench version v9.1.3. Opened the SensorTag project from C:\Texas Instruments\BLE-CC254x-1.4.2.2\Projects\ble\SensorTag\CC2541DB in IAR and completely rebuild the project. Downloaded SensorTag.exe from the path: C:\Texas Instruments\BLE-CC254x-1.4.2.2\Projects\ble\SensorTag\CC2541DB\CC2541DK-Sensor\Exe using CC Debugger into CC2541-SensorTag unit.

    2. Second CC2541-Sensor Tag. As-Is without changing any software.

    Installed the Android app on my Samsung tablet from: play.google.com/.../details

    Now in both the above sensorTags, after opening the app, I pressed the side button on the sensor-tags. Both of them gets discovered with their respective MAC addresses. But, I cannot proceed further as nothing happens. I could not connect to either of the sensortags or cannot open the monitoring page to look at the sensor values. Please help further.

    Regards
    Sandeep.

    Try to use play.google.com/.../details on your Android system to test with your CC2541 SensorTag again.

    Hello,
    Already posted the results with the Android App in the link above. Again I tried to connect with CC2541...but same results (as posted earlier)without any success. Also from the link, it is evident that CC2541 is not supported in this app; extract below:-

    The following development kits are currently supported:
    CC2560 LaunchPad - www.ti.com/launchxl-cc2650
    CC2650 SensorTag - www.ti.com/sensortag
    CC3200 SensorTag - www.ti.com/sensortag
    CC2650 Remote Control - www.ti.com/rc

    Regards

    For your reference, I just download CC2541DK_BIM_SensorTagOadImgA.hex in \BLE-CC254x-1.4.2.2\Accessories\HexFiles\ to my CC2541 SensorTag and test with my Lenovo TAB S8-50LC tablet. Everything works fine.

    YK Chen, Thanks for your response. Can you help me with the following inputs:-
    1. Which is the workspace that is used to build this project? Is it C:\Texas Instruments\BLE-CC254x-1.4.2.2\Projects\ble\SensorTag\CC2541DB ?? Otherwise pl let me know.
    2. Using IAR Workbench 9.10.3. After opening the project file, I tried with CC2541DK-Sensor, CC2541DK-SensorOAD-ImgA as well as -ImgB. But have the issues. Is there any specific configuration changes that needs to be done?
    3. Please let me know the Android version on the Lenova TAB? Do you see any minimum version requirement for the sensorTag to get connected?
    Regards
    Sandeep

    1&2. It should be built by CC2541DK-Sensor project in C:\Texas Instruments\BLE-CC254x-1.4.2.2\Projects\ble\SensorTag\CC2541DB and I build the example by myself to test without problem.
    3. The Android version is 5.0.1 on my Lenovo TAB.
