wifishield esp 8266

[hanmegs]

just want to ask on my cytron wifi shield, there is no error on my code, but somehow it got stuck on the middle of the process..the compiling and uploading process are successful. once i open my serial monitor, it can connect through the wifi network but then the shield are not blinking..the blue color led and tx led is stop blinking. when i try using the example, it work correctly. may some some help me..
tq in advance.

Hi,

May I know what is the process that stuck in the middle? Can you specify the problem in details? What is the example you are using? If you can show the results in Serial monitor in screenshots it will be better for us to troubleshoot the problem.

Thanks.

hi bengchet,

tq for the reply. im using Cytron wifi shield esp 8266. it suppose to connect to the network and show the result. how ever, when it manage to connected through the network, the tx and rx led is stop from blinking and the blue color on the esp also stop blinking. when i opened the ip address on the browse, it say that my arduino not send any data..here i attached with the image..


here is the code that i used. it not fully edited yet.. tq for ur help..

Hi,

The problem might come from do{...}while(1); The program will keep running in this iteration and will not go back to the first line of void loop(). Function server.available at the first line of void loop() is important for continuous connection between your browser and wifi shield. So you can try reorganise the coding and see if the problem still exists.
