[ERROR] after switch On

I have hardware connections by design guide, but my WizFi210 returning [ERROR] allways after switch power on or after AT+XRESET command. Otherwise, it appears that operates normally. Does anyone know what could be?

Hello daveport

There is no problem.

After power on, WizFi210 would try to connect to a specific AP. That is the default setting.

In short, WizFi210 boots within 100ms and tries to connect to a specific AP for 3~5 seconds. If that is failed, Wizfi210 returns an “[ERROR]” string.

If you issue command, you can remove the .
