Hi, I am new to Arduino and started to play with OSOYOO robotic car kit. It comes with an Arduino clone and an ESP 13 wifi shield with DOIT firmware in it. I am pretty sure, its the DOIT one, as it is written on the shield and I get a response on 192.168.4.1 providing the config page. The shield is placed on Arduino as expected. USB cable connected to Arduino. No extra power, just the USB. And come the issues:
1) If I plug the USB cable to my PC, only the red LED on the shield lights up. I have to push the "RST" button on the shield to get the blue LED light up too.
2) I use the guide at https://fineshang.gitbooks.io/esp8266-based-serial-wifi-shield-for-arduino-user/content/chapter4.html, or the OSOYOO guide at http://osoyoo.com/2016/09/18/esp8266-uart-wifi-shield-use-guide/, which are almost the same. Even if the blue LED lights up, I connect to the "DoitWiFi_Config" wifi network and click submit. Exactly as described in steps 1 to 3. However, I do not get any further, as the blue LED doesn light up any more and the wifi with SSID "DoitWiFi_Config" cannot be found any more.
3) Moreover, if I change anything on the config page, say the SSID to "MyShield" instead of "DoitWiFi_Config", this does't get saved!!
Well, my question to you, if I may dare to ask, would be: a) Does any of you similar experience and any solution for this? Or am I doing anything wrong? b) Is there a way to flash the firmware in the ESP8266 to the AT one, that would work with this shield? I have looked through many post in several forums, but did not find anything, that would work.
Thanks for help. Milan
