[asma]

Hello,

In our project i am using nrf51822 with stack Softdevice S110 . We want to connect it with Samsung Gear S2.Is it possible with stack s110 or i have to use stack s130 , as Samsung gear S2 specification shows it support bluetooth v4.1.

Thanks & Regards Asma

If the gear 2 watch has an working API for BLE I don't see any reason why it shouldn't work. However I haven't seen much information of the ble capabilities of the gear 2...

i tried making connection of gear S2 with S110 stack v 7.1 . it showing some difficulties in connection as gear S2 is v4.1 compliant and S110 is not 4.1 compliant.

Whether a device is 4.0, 4.1 or 4.2 usually doesn't matter. Do you have a sniffer trace showing what is happening on air?
