[RFC BlueZ 34/35] tools/mgmt-tester: Interleaved stop discovery (BR/EDR dev. found)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This test will check the stop interleaved discovery during inquiry. For
this, it verifies the following:
- LE Set Scan Enable HCI command is received,
- Device found event (with BR/EDR device) is received,
- Inquiry cancel is received, and
- Stop discovery is succeed.
