    Hi, 

    Can't understand question clearly. 

    Do you mean , you updated image via OAD or via programmer?

    For OAD choose "CC2541DK-Sensor-OAD_ImgA"configurations while building the image and when you want to flash image using "Erase, program and verify" option choose "CC2541DK -Sensor" setting for building hex file.

    Hi,

    Which configurations have you chosen while building hex file. 

    On left top IAR embedded workbench, which workspace configurations have you chosen?

    Can you describe steps which you have done? It'll be more helpful to understand problem. 

    thank you.

    Hi


    Below are  the step i have followed .

    To read or write a hex file to the CC2540/41, select the “System-on-Chip” tab (default). The connected

    CC2540/41 should be detected and show up in the list of devices. Under “Flash image” select the desired

    hex file that you would like to write to the device. If you are reading from the CC2540/41, under “Flash

    image” enter the desired path and filename for the hex file. To write to the CC2540/41, under “Actions”

    select “Erase, program and verify”. To read from the CC2540/41, under “Actions” select “Read flash into

    hex-file”. To begin the read or write, click the button “Perform actions”.

     

     

    After this i can not  scan /detect the device  .

    IS there any way i can reset the BLE device?

    Thank You
