IDE and SDK for Module EC200U-CN

hello, I started hands-on on the EC200U with UMTS&LTE EVB kit. I dont know much about this board so please help me by referring the suitable SDK source and which IDE will be used for development on this board

LTE01R02A09_C_SDK_U is the latest SDK for EC200U; LTE01R02A08/07/06 low version Can also be used. VC CODE can be used to compile the SDK, * If you have another IDE that you are familiar with I think it is OK.
I hope these suggestions will be helpful to you.

Thank you for your support.
