Dear @yithwe,

May I know upon mDNS started, are you able to obtain the network port broadcast from Ameba board?

Hi dakamaster
yes, I found the new network ip port from Tool–>port–>Ameba_10AC20at 192.168.6.106 as below.
but when I select this port, appear
“No monitor available for the port protocol network.Could not connect to XXX network port.”

Since you are currently opening your Serial Monitor, there might be a conflict if you want to display your data from the network port to your serial monitor. Thus, could you please close the serial monitor tab and try to select your network port again.

Thanks

Hi dakamaster
Is this OTA flow must need to use Arduino IDE to download? may I use web site or cloud?
