Response to AT commands

[tonegas]

Hi all,

I'm starting to use WROOM-02. I wish to communicate with this module with AT commands. The module answears OK with certains commands, but if I want to set/get the state, for example, of GPIO I read ERROR. where may be my errors?

Thanks

Do you mean that you cannot read GPIO? Maybe you should have a try with the latest AT firmware. Mine works fine.
