I need to specify a subnet mask and a gateway to my ESP01. The command below seems to be executed without error, but i cannot ping the device after.
AT+CIPSTA="192.168.1.152","255.255.255.0","192.168.1.254"
only this works (I can ping the device and access other PCs locally)
AT+CIPSTA="192.168.1.152"
however it is not able to communicate with the outside because it is connected to a VLAN.
