CC2640R2F: 使用CCS导入一个BLE5-stack例程simple_central,调用GapScan_enable(0, DEFAULT_SCAN_DURATION, 0)后程序死掉

2023-03-03 分类：蓝牙Bluetooth 技术 阅读(193)

Part Number:CC2640R2F

如题，SDK版本是SimpleLink CC2640R2 SDK – 4.30.00.08.

我在程序中添加了看门狗，发现调用GapScan_enable后过一段时间程序就复位了。

可以确定硬件是没有问题的，我有一个老的工程SDK版本是simplelink_cc2640r2_sdk_1_40_00_45工作正常。

我初始化了串口，通过串口接收一个指令后调用SimpleCentral_doDiscoverDevices开始扫描，程序执行到GapScan_enable就死了

我已经附上了代码。simple_central.csimple_central.h

Katherine Wang：

已为您联系TI工程师，稍后给您回复

要解决此问题，我建议您过滤掉广告结果、缩短扫描时间等。
