I am currently constructing a Voltage Protective Relay design on my PSoC 4 BLE 4200 device. The issue is that I am having difficulty to create a custom Bluetooth profile. The thing I am trying to do now is implement Bluetooth controlled threshold voltage range for my design; more specifically, i am trying to use the CySmart for IOS devices, to adjust some variables' value inside my program. So i am wondering that is this approachable? if so, could you please provide me some related examples?
