1. App dosent communicate well during locked mode..
2. If esp comes/goes out of range then app shoud play a notification sound.
3. Some time esp and app are connected but..esp behaves like it is freezed or not communicating with app..until i reset the power of esp
my app is working good ...i use a data rx/tx between app and connected esp module so that esp can make a pin high when client(mobile) is connected ..but when mobile is in locked/sleep mode .. problem begins..and as i unlock the mobile again it works fine..
