    Inter Frame Space (TIFS)

    AnBa_330971

      BLE standard specifies the Inter Frame Space (T_IFS) to be 150 usec.

      In a scanning situation, the standard contains a diagram where SCAN_REQ -> T_IFS -> SCAN_RSP (attached is a diagram from the standard).

      Does this mean the responding device will send out the SCAN_RSP exactly 150 usec after it receives SCAN_REQ?

      150 usec seems like a very short time for message processing.  Or is it a minimum value so it could still take as long as msec?

      Thanks,

      Andrew
