Port 51042 should be open to incoming connections, over TCP (open it to all applications).

Did that, but still no connection to the server.
As I said, it worked once, but after powering off the ESP it did not connect again.
Is a sequence in actions to be followed?
Besides the firewall settings, what shall be done first: Resetting the ESP, starting the B4J App, and anything more?
The B4J server shows up in the Wlan as "TestAp". I don't see where this is defined in the B4J IDE.

Please test it with the code I posted in the first post: https://www.b4x.com/android/forum/threads/b4r-v1-20-beta-support-for-esp8266-boards.68213/

It doesn't matter which one you run first.

Also no success with Erel's code.
Which IP address do I have to use in the B4R code:
Private serverIp() As Byte = Array As Byte(192, 168, 0, 6)

The server is the device running the B4J application.
If f.e. the B4J application running local on a PC, get its IP address (via f.e. ipconfig) and set the ip address in the B4R Code accordingly.

rwblinn: Thank you. It works now. Not having known that caused all Sunday's work....

But there must be some other trick to get them connected. Having changed settings more or less randomly (forgot what it was) I had them connected once without having entered -for sure- the PC's IP-address obtained from IPconfig.
Concerning the LED, is D4=GPIO2? (Using ESP8266-01)
