Hi there !
i'm here for ask your help. I start control an ESP32 with AT command from serial port and but right now i'm in front of a wall. let me explain : what i wanna do is check all wifi connection around to me send this information on website make my choice send to the ESP32 and try to connect to the WIFI . I did this step;
- AT\r\n and i recive ok
- AT+CWMODE=3\r\n and i recive OK i configurate in AP an STA
-AT+CWLAP\r\n return all wifi around me
- AT+CIFSR\r\n and return my IP address 1920168.4.1
If i try to connect with external device like my cellphone i can see +STA_CONNECTED:"here i receive my mac address"<CR><LF>
-AT+CIPMUX=1\r\n and i reciìeive OK
-AT+CIPSERER=1,89\r\n and i recive ERROR
and i don't understand why o mabye i think is because right now i'n not connect with router is right ?
