wizfi360 returns ERROR frequently

I am using wizfi360 module.
I am able to connect via default baud rate, however most commands I issue return ERROR.


If I repeat a few time, one attempt might succeed.

Please help.

problem solved.
I was using teraterm and keyboard input was flushed as i typed each key.
need to send full command at once.

Dear haricane00,

How about using the YAT to send AT Command? The YAT is free software, and it is possible to predefined commands. You can download it at this repository(Release/WizFi360-Open.yat at master · wizfi/Release · GitHub).

thank you Taylor, I will try it out
