Hi.

I am using  android phone & Psoc 4 Ble Pinoeer kit 

In cysmart tm  mobile app ,It is discovering Ble device

But when I clicked on it to connect it is showing NO service found.(service discovery status failed with error code :129)

Even in the Cysmart 1.2 windows pc app

It is connecting with BLE device , and discovering all the attributes

But when I try to read or write attributes it is showing, Read characteristic value timed out.

Please help me to find out the problem.

Hello Deepa,

Please change the UUID values of services and characteristics in the profile tab of Bluetooth component. Because automatically generated UUID values cannot be accessed by some Android versions.

We have to call the events continuously by using CyBle_ProcessEvents() function.

Thanks,

PSYU.
