Hello, I am a Physical Therapist and I have a patient that often forgets his walker when he get up to walk causing him to fall. Is it possible to make a bluetooth device that he can wear on his wrist and attach another to his walker and when he gets 1 meter from his walker an alarm would go off. Thanks very much.
I am not sure if that short of a distance can be discerned. Hopefully someone with more experience will comment.
