I hadn't n been able to find if there is a way to join the two together? I need to use the WiFi as a really long cable.

please draw/explain your configuration, thanks

darkstar2002 commented 5 years ago

device a -> serial to esp -> wifi ->esp - > device b

uzi18 commented 5 years ago

id device a or b is Arduino with ELClient library, it is possible :)

darkstar2002 commented 5 years ago

lets say device a is a computer and device b is a nextion screen

uzi18 commented 5 years ago

if so, esp-link need some improvement here ;)

why not like this:

map tcp connection to virtual com port on PC with one of https://superuser.com/questions/54723/any-free-application-to-redirect-serial-communication-to-tcp-ip
pc -> virtual serial -> esp-link -> device_b

darkstar2002 commented 5 years ago

not an option its a closed system. Thats why i would like to just link the 2 esp together and send the serial between them.

+1 Same thing here .... i would like to link a nextion display to a battery management system .... both are 50 m apart. Both locations have wifi available. The BMS and the Nextion provide normal serial ports.

Doesn't the stock AT firmware do that? Esplink on one(dial in) side, AT firmware on the other side (dial out)
