I have a ESP-WROOM-02 connected to an ATmega1280.
I have level conversion in place.
I have managed to get the boot response from the module.
Other than by scope, I don't an have a simple method to
monitor the input and output. So I cannot (at this point) let
you know what the boot info includes.
When I send a command string to the module, it does not
The string being sent is "AT+CWMODE=3", followed by '\x0D', '\x0A'.
The module is clocked at 26Mhz and I have measured the TX and RX
baud rate at 76.8k.
I have confirmed that the RX data does arrive at the RX pin on the module.
A couple of questions:
Does anyone know whether or not parity is being used?
Does this module (ESP-WROOM-02) come with preloaded with firmware?
Newbie with this part so any suggestions would be helpful.
