Dialog Smartbond Bluetooth Low Energy – Software // Dialog “Smartbond”系列低功耗蓝牙—软件

Hi Dialog,

我们在做一款监护手环类的产品,需要14580做蓝牙主端,同时控制GSM通信模块的电源
软件上我们设置了app_default_sleep_mode = ARCH_EXT_SLEEP_ON,有时需要拉高 GSM的电源控制IO 并保持,但是测试发现IO口的电平在进入低功耗之后变低电平了
于是我在periph_init函数里面添加了恢复IO状态的代码,但是仍旧有10微秒的IO下降沿,这样我的受控的GSM系统会短暂断电导致异常
想请问下有没有什么办法能在低功耗状态下保持住IO的状态?
还是我这种场景就不能使用sleep模式了?

谢谢
Best Wishes
Walt
