6.0. Commands
6.1. SPH_to_RDR_Reset
This reset command will not send any message to ACR31. Instead, the mobile device will generate
several pulses in the right channel of the audio jack that will trigger the ACR31 to perform a hardware
reset. This is the only way to resume the normal operation of ACR31 after it has entered the sleep
mode.
No response will be generated for this command.
