Hello,
I purchased Pan1721 (TI cc2541 chip) Evaluation kit. I downloaded TI Quick start guide & demonstration files from Panasonic website. I installed BLE-Stack (for CC2541) software from TExas instrument website. When i connect Pan1721 Evaluation kit, i am getting a message USB device not recognized. I tried to update the driver software manually (in device manager) by giving the path of the driver software which came with TI Quick start guide & demonstration files. Then i am getting a message "The best driver software for your device is already installed" and unknown USB device. Will someone please help me in installing the right driver software. Thanks.
