AT+WOPEN=3 throws error

As per API description, AT+WOPEN=3 should clear user area of flash. But I am seeing error on this AT command. Any suggestions?

you only can clear area of flash, only if the application is stopped.

stop your application first with at+wopen=0, then erase it with at+wopen=3

Thanks a lot… very logical… missed it.
Wil try that and update…


did U try it ?

success or not ?

I will do it in the evening…
I dont have access to HW right now…
