ESP8266 as simple WiFi-Serial adapter

dlh · Post by **dlh** » 06 December 2017, 5:19 AM

I have an application where I want to replace the serial interface on the XTB-232 with the ESP8266.
http://jvde.us/xtb_232.htm
It needs to connect to the XTB-232 PIC UART at 4800bps and merely needs to relay comms traffic to/from WiFi.

Would anybody have relevant ZBasic for ESP8266 code?

ok, not a zbasic solution, but it works perfect as TCP2RS232 bridge ...

Thank you! I had already found https://github.com/beckdac/ESP8266-transparent-bridge but this looks much better.

I need to study it but hope I can use this https://www.hw-group.com//products/hw_vsp/index_en.html virtual WiFi serial port with it.

That's the first post. The most recent is Thu Nov 09, 2017. Click on page 42.

BTW, what do you use for flashing it to the ESP8266?

ouuuu I became old LOL

I just use NodeMCU Firmware Flasher ... works perfect ...

In client mode, can the ESP8266 connect to an AP that has a hidden SSID?

in general yes, in particular for this firmware, only the author can answer ...

btw. the firmware I provided in my first answer is NOT the same than from yours ...

This drags things off topic but I found a different solution. See USR-C215...
