Data corruption in app side

[Thomasthomas]

Hi all, 

In my project am sending ecg values over ble to android app. During first connection, the values are received and seems to be no problem, but when i disconnect and connect again i got corrupted values in the app. In order to get the correct values, i need to close the app and start again. How to solve this issue?

the problem exist only if i disconnect from the app and then connect again, but if the app is closed fully and then connected, then again the ecg value is correct. is it a problem with app or device (uart service) during disconnection??

Please check the code of your app. Also verify if the data via BLE is correct or not, either by using a sniffer trace or using NRF Connect app on the phone to test.
