Hello!

Im trying to connect a ESP88266 module to my arduino. Therefore I'm using this scheme:

1161×942 88.6 KB

I'm not sure if I should connect the CH_PD pin or not. In other examples they don't connect it.

For testing I use the following code:

#include <SoftwareSerial.h>

SoftwareSerial wifi(2,3); // RX, TX

void setup()
{
Serial.begin(9600); // FTDI
wifi.begin(9600); // GPS; 9600 first time, 38400 second time
}

void loop()
{
if (Serial.available())
wifi.write(Serial.read());
if (wifi.available())
Serial.write(wifi.read());


}

I tried several AT commands, but I get no response at all. Tried different setting for baudrate as well. No results.

Any ideas on what I can try?

Im now able to get something out of it. But it doesn't make any sense.

It are strange values

Any thoughts?

Do you use CR+LF in your Serial Monitor or "....\r\n" in C?
Have you tried 115200 baud?
