It has been, for me, so frustrating to not have a spec sheet, I would suppose a "data sheet" might help.
As far as my connection problem I have connected 4 of the five ESP-201 modules I purchased.
The one I have not been able to connect, the one where the blue and the red led are on constantly is of course the
the one that I hard soldered on a perfboard. The others I made up a socket for so I am able to switch modules.
Well 4 out of 5 isn't to bad. Possible with my reflow gun I'll be able to remove the 201 module and start over.
Thanks again for the replies.
