thank you for the reply, the problem was with the code on github which for no reason works with the sdk, better use the sample code supplied within the sdk.
a working code for ios can be found here: https://github.com/askari01/Lego
i have location enabled but still i am seeing the message Trying to find out where you are. if anyone can reply i would be very helpful.
