Unable to locate CC2540_ble_single_chip_peri.lib about biscuit HOT 1 OPEN

I believe all of TI's pre-compiled BLE lib files are in C:\Texas Instruments\BLE-CC254x-1.4.0\Projects\ble\Libraries\Common\bin. Your version of the TI stack may be different than what I'm running (1.4.0) so they may be slightly renamed, but you can usually tell by looking at the filenames.

The download link you pointed to is a copy of the example BLE sample projects that you can download from TI's site if you go look up the CC2540/CC2541 SoCs. You will also need an 8051 compiler to run any of those project(s). RedBear recommends IAR Embedded Workbench (and you can use their 30 day unlimited 'code' size trial to compile all of the projects) otherwise you'll be shelling out $3k+ for a license.
