I have an ESP8266 connected to an ARDUINO DUE. The problem is, that when I try to connect to my access point via the example program "MultiSerialMega" uploaded to the DUE and with the following command send via the serial monitor
AT+CWJAP="Was ist gruen u. stinkt n. Fisch","1111111111111111"
I get an "error" as reply. When I shorten the access point's SSID to "Was ist gruen" then the ESP8266 connects. So seems to be a problem with the length (it is more than 64 bytes) of the string. I came to the conclusion that the buffer size of the serial buffer of 64 bytes could be the prolem, so I changed
#define SERIAL_BUFFER_SIZE 64
#define SERIAL_BUFFER_SIZE 256
in "RingBuffer.h", restarted the IDE and uploaded "MultiSerialMega" again, but I still get an error when using "AT+CWJAP="Was ist gruen u. stinkt n. Fisch","1111111111111111"".
As I have connected several devices to my access point, it would be nice if I would not have to change the SSID of it! Thanks for the answers in advance!
