Mobile BLe V 4.2 does not connect with Nordic chip(N51822)

[Arun]

I am working on BLE Applications, I have tested with different devices like Nexus, Moto, Samsung, LG(ble V 4.0). I am getting the GATT Error 133 in Samsung Devices alone(Samsung A5 2016 & BLE version 4.2).

Error 133 is a known issue with Android device. Please search "Android error 133". We don't know a clean fix for that yet. Turn on and off Bluetooth sometimes helps.
