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

I believe you are refering to Fig 4.3 of your attachment. The IFS should be perceived as the minimum amount of processing time before the sending of the next frame, on the same channel index.
