Hello everyone, i am doing an indoor position device, which explains the code below. But i am facing a problem and that is, when i set bool remote = false ( meaning i'm using a local device ), everything works out perfectly. But when i set bool remote = true ( meaning i'm using a remote device ), im facing problems adding my anchor address to the device list of the remote tag. ( if i'm not wrong thats the problem that is occurring to me right now). If anyone spots any error in my coding please reply to this post and let me know 
Thank you very much for your help Much appreciated
