My name is Przemek and I'm starting my journey with ESP8266 module.
I hope that I posted it in correct section, if not - please forgive me and let me know when I should put that kind of question.
I need transparent bridge connection between uC and ESP.
I did firmware update and after that - when I try to connect to my ESP module(usign serial monitor and CP2102 USB-UART module) I can't switch to command mode(using +++AT for example)
Module is silent, I can't communicate with it. I don't know on which state it is actually.
Im using ESP Flash download tool, all needed informations(like offset) are set correctly.
When I'm doing downgrade to 00200.9.4 for example - everything start working correctly(but I can't start transparent mode - for every command Im getting responses on serial - that's something what I need to get off...
I tried many different "transparent firmware" - 0x40000.bin, 0x00000.bin and also others like original by jeelabs - but everytime after update I cant talk to ESP...
If you can point me what Im doing wrong - or what other I can do - Iwill be very thankful.
Please help, thank you very much.

Regards

Przemek

After loading the esp link firmware, scan for WiFi access points using a phone, tablet, laptop, etc. Connect to the esp link AP which has a name like "ESP_XXYYZZ". Next use a web browser to connect to http://192.168.4.1. You should see the web UI. See the esp link web site for full details.
