Hello Robert,
For your specifications of sampling at 10 usec, I would have to say that BLE on a CC254x device would not meet your requirements. The CC2541 operating in proprietary mode could work for you. You would then have to send the data at a time interval that would fit within the 5-6KBps throughput rate of the BLE mode. A regular timer would have to be used instead of the OSAL timer.
With such a high sampling rate for you sensor, you would not be using the CC254x for its low energy option. I will make a guess that you want to interface with an iOS, Android device. If that is the case, you should look at doing it using the CC3000 SimpleLink WiFi module and a faster MCU. This would allow you to sample at a higher rate and communicate with an iOS or Android device.
Take a look at the following for details on the CC3000:
