ESP8266 Community Forum

Hi, I have this ESP8266 board: http://linksprite.com/wiki/index.php5?title=LinkNode_D1, and I'm trying to make it work with this shield: http://www.tinyosshop.com/index.php?route=product/product&product_id=464. It works fine with this smaller one which uses the same module: http://www.ebay.ca/itm/New-SIM900A-V4-0-Kit-Wireless-Extension-Module-GSM-GPRS-Board-Antenna-Tested-FE-/331634149190. This leads to me believe that there is no reason why it shouldn't work and yet I am having issues communicating with the shield or making it work with the provided library (which works fine on Arduino). I doubt that I will be lucky enough that anyone reading this will have experience with this specific board and shield, so I guess what I'm asking for is general guidance on using shields with the ESP8266, what are common sources of problems and things to keep in mind while I struggle to get these things working together. Thanks a lot!

EDIT: I get this stack dump when I try to run the code, what can be the cause of this?

Try to put this report inside ESP Exception Decoder. There is 'Soft WDT Reset' so I guess that reason is too long loop somewhere in Your code or library and software watchdog timer is fired.

Thank you for your reply and sorry for the delay. I tried what you suggested and I narrowed the problem down a little bit to a few lines in the code, strange since it is code provided by the manufacturer and it works fine on a plain Arduino. Still thanks for the guidance in what the problem can be, I will try to debug it.
