Hello, I have 3 RX stations. I just recovered the one that was at my brother for some changes of the box.
The RX, despite the flash of the latest firmware has retained its old IP address: 192.168.10.10 while it should connect in 192.168.1.x here.
I do not have wifi with this address range at home, or my neighbors.

The identifiers are the good ones because I use the same software on another test RX in my home  and which is correctly connected.
The points remain red, so it is not connected.

Code:

ESP8266 FW Version: AT+GMR

AT version:0.60.0.0(Jan 29 2016 15:10:17)
SDK version:1.5.2(7eee54f4)

OK
Mode station OK
Join AP success
IP: 192.168.10.10
Multiple mux OK
Start tcp server at port 80 OK
STATUS:2
Set tcp server timout 30 seconds
ESP8622 init end

an idea? is it possible to assign a fixed IP in the app?
RX board is V1.3.
thanks.

You have something bad ... Maybe your DHCP server? If RX joined to your AP successly, your DHCP server
should allocate any IP address from its range, but RX has still its old IP address ... You could restart: 1) RX unit,
2) DHCP server, 3) WiFi AP unit ... If this does not help, you have to look into the DHCP server log on what's going on.
Good luck.
(And I recommend, like Werk_AG, to assign a fixed IP address in your DHCP server corresponding to the MAC address of the RX unit.)
