I try to develop app using blutooth PMP example and successfully execute without error. Then I try to add ability to send/recv data using cperiodic with delay 1000 microsec. When I try it, the phone restart after connected and transfer data for a short period. I solve this with add the delay (i.e. 50000 microsec). This is a problem because I want to make an arcade game. Any solution? Do I have to use thread?
