Both works in StationAP mode
The first module connects to a router
the second module connects to first modules softAP
the first modules softAP acts as a tcp server
the second modules connects to the first modules softAP as a tcp client
data transfer between both is working as well
now when i connect my laptop to the second modules softAP and start a tcp connection , everything works perfectly. The second module receives the data , but when i try to send the received data to the first modules tcp connection i get a -12(ESPCONN_ARG) error. Can any please help me with this problem?
Thanks in advance.
