Can you please check with different mobiles. Can you please share your project?
Thanks for replying.
Earlier it was not working on any device with the module. Then I changed the project, that is created new project with the same code.
It worked like other two modules. It is discoverable.
But there are some issues (irrespective of the module)
1) Sometimes the device gets disconnected (more so on specific devices, even though the android version of the device is same).
2) On some devices the services are not discoverable (although the ble module is visible)
