    Hi,

    Yes I know we developed the app, but the Bluetooth chipset in the phone varies over models and some doesn't expose full functionality to the app. Have you tried multiple vendors?

    But the problem is its working with few smart-phone(like nokia , LG ) and not at all working with other smart-phone (like lenovo and moto).

    Could you let me know the condition for not working with other smart phones . Is it something with BLE version ?

    Hi,

    The various BT chipset in phones supports different amount packets per connection events for example, furthermore it's often a combo-chip and has to share resources with WiFi. There is nothing we can do than complying to the spec in order to ensure interoperability, but sometimes that is not enough and applications is in need of tuning to support all use cases..

    Many Bluetooth low energy products state what phones and OS versions they are compatible with. This does not have anything to do with our SDK or the HW, it has to do with the use case and expected behaviour.
