today I had the chance to play around with my ESP8266. I've wired it up with my Raspberry Pi and got it responding first at 9600 baud. Then I used the command AT+CIOBAUD=115200 to switch to a higher speed. I've restarted minicom with the adjusted parameter and all was fine. Then I've tried the next step: AT+CIOBAUD=230400. But since then I can't communicate to the ESP8266. I still see him in the WiFi, can send a ping, but I can't get anything in minicom.
I've switched also to a Windows PC and a USB to RS232 adapter. There I've wired up everything and used teraterm to connect. The only thing what happens when I power up the ESP8266 and then type something in teraterm is that the blue led on the ESP8266 lights up.
Hope someone could help. Is there a possibility for a factory reset?
Best regards
