The first part prints at 74880 and 'ready' prints at 115200.
The problem is I can't get anything to respond after the ready prompt. Here's what I've done:
Verified rx and tx are at 3.3V.
Used putty to send AT<enter><ctrl-J>
Used esplorer to send AT (esplorer says it can't detect fw.)
Tried to program with esplorer, cannot sync.
Tried 2 of the modules, same thing.
I question if this devices has the AT firmware loaded. What does the ready prompt mean? What commands should it accept?
Any help is appreciated.
