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?
