SPWF01SC UART not responding

[VShri.1]

We have used Wifi Module “SPWF01SC�? in one of our projects. Now recently we are getting more issue in wifi module.

Most of the modules are not responding to AT commands. Can you please suggest possible troubleshoot steps to resolve this issue.

​Hello,

If no message are printed at boot, I kindly suggest to verify the UART parameters (speed and flow control). If the problem is still there please share the command log that leaded to unresponsiveness.
