From 9cb4f271127ea4ef428e873a7f76bc02919e3217 Mon Sep 17 00:00:00 2001 From: Harald Welte Date: Sat, 28 Apr 2018 21:38:58 +0200 Subject: LMSDevice: Call LMS_Init() before setting sample rate LMS_Init() will override basically all device settings with their default value, including the sample rate. We hence have to make sure to call it before any other API function that changes the device config such as sample rate, frequency, filter bandwidth, ...
