I am using AT commands. Did anyone else experienced problem with AT+PING command? It seems to be not working, I always get timeout error:
AT+PING="192.168.1.13"
+PING:TIMEOUT
ERROR
When I try to connect to the same IP everything it's working fine:
AT+CIPSTART="TCP","192.168.1.13",5020
CONNECT
OK
Clearly there has to be some problem with PING command.
