Hey,

i've recived my two ESP8266-01 Modules.
I cann connect via Serial, List APs and all,
but when i try to connect to an AP, i get an immediate error.

Firmware:
Code: Select allAT+GMR

AT version:0.21.0.0
SDK version:0.9.5

Code: Select allAT+CWMODE=?

+CWMODE:(1-3)

OK


Code: Select allAT+CWLAP

+CWLAP:(3,"FRITZ!Box 7362 SL",-94,"08:96:d7:db:4e:15",1)
+CWLAP:(4,"FRITZ!WLAN Repeater N/G",-68,"06:24:fe:1a:ed:7b",1)
+CWLAP:(4,"BurY-Home",-79,"c0:25:06:65:f8:49",2)
+CWLAP:(4,"FRITZ!Box Fon WLAN 7240",-86,"c0:25:06:b4:96:7f",2)
+CWLAP:(4,"burrry",-31,"30:b5:c2:6e:97:97",3)
+CWLAP:(4,"GiniFritzbox",-95,"34:31:c4:35:39:a4",1)
+CWLAP:(3,"WLAN-11F231",-91,"88:03:55:11:f2:59",11)

OK


When i try to connect to one of the APs, i get instantly an error and some cryptic chars:
Code: Select all<\0><\0>P????*<20>U<18><18>??????b<2><18><18>??z?J??<17>?!I??U?<\r><\r><\n>
<\r><\n>
ERROR<\r><\n>


I've tested with ESPlorer and Serialport-Terminal, connecting with:
Code: Select allAT+CWJAP="burrry", "password"
AT+CWJAP="burrry","password"
AT+CWJAP=burrry, password


But nothing works. Any Idea?

It doesn't ring any bells to me. It might be possible to get some additional diagnostics by connecting a USB->UART to UART1. I believe that writes some additional diagnostics. Do you have a second ESP8266 to test against? Maybe describe the nature of the access point to which you are connecting? Are you able to test against a different access point?
