A system for implementing a relatively reliable wireless transmission protocol for a processor-based system includes generating commands associated with a predetermined number of command identifiers. Thus, no more than the predetermined number of commands may be issued until a responding device responds with a previously used command identifier. When a device responds that it has received a command with a given identifier, that identifier then becomes available for reuse. Thereafter, a new command may be issued by re-using that command identifier. In this way, the system may keep track of all the outstanding commands, ensuring that a lost command will be detected. By limiting the number of command identifiers, the requirements of the receiving and transmitting devices in terms of processing power and/or memory capacity may be effectively limited.
