MP Test Note

• If you want to continue the MP test, don’t do this command “mp_stop”, it means you want to finish MP test and switch to Normal mode (Scan and Connect AP).
• Change the config parameter (Rate, Channel, Power index, Bandwidth) or to continue the other MP test, please must first to stop Tx, command “rtwpriv wlan0 mp_ctx stop”.
• We must make sure that the instructions have been completed and command in order.

Your MP Test Programs should wait for a return string after executing the command.

Example:

rtwpriv wlan0 mp_start The return-string is: “wlan0 mp_start:mp_start ok”

Please check return-string to confirm the command is set completely.
