مشکل با سریال hc05

[farhadi7031]

سلام دوستان
من یه پروژه کنترل چند رله با استفاده از ماژول بلوتوث hc05 و میکرو دارم میسازم
وقتی که برنامه به قسمتی میرسه که میکرو برای بلوتوث دستورات کامند رو ارسال میکنه در همون قسمت میمونه و جلوتر نمیره تا اینکه سیم اتصال سریال میکرو رو قطع کنم تا برنامه ادامه پیدا کنه
لطفا راهنمایی کنید خیلی واجبه
این برنامه:
