Subject: [BlueZ PATCH v5 2/3] core: Add param to disable interleave scan
Date: Tue, 29 Sep 2020 18:56:03 +0800	[thread overview]
Message-ID: <20200929185522.BlueZ.v5.2.Iac5207375d22fb7b96ae4ef73b49ae4ab457219c@changeid> (raw)
In-Reply-To: <20200929185522.BlueZ.v5.1.I1f083629d41c747a33a3937fbc199ea37dccde12@changeid>

This patch adds parameter to enable/disable the interleave scan feature.
---

Changes in v5:
- Fix compile warning

Changes in v4:
- Set type of EnableAdvMonInterleaveScan to u8
- Add support of different sizes of parameters

Changes in v3:
- Set EnableAdvMonInterleaveScan default to Disable
