Abstract

The USB-OTG allows USB device to device communications without the use of a PC. The session request protocol (SRP) is used to establish this logical connection, and the implementation of SRP may impose some software real time requirements that may be difficult to achieve in some systems. This paper describes an implementation that avoids this problem.
