Thanks for sharing your project.

I have an issue with compiling using build.bat in a9g folder, it just returns " '.' is not recognized as an internal or external command"

I have the same folder structure as setup in Github. I have also tried copying a9g and mailbox into GPRS_C_SDK and would get a build failed error. Running ./build.bat a9g

I have tested ./build.bat demo gpio and it completes successfully.

Could you please point me in the correct direction?

Excellent work. Thank you! I wanted to know how you solved cJSON_Parse. It always returns NULL, I can't figure out what the problem is. Can you help please. Part code:
char msg_json[] = "{ "state":{ "desired":{ "NumValue": 3 } }}";
cJSON_Hooks memoryHook;
memoryHook.malloc_fn = OS_Malloc;
memoryHook.free_fn = OS_Free;
cJSON_InitHooks(&memoryHook);

cJSON *json_processing = cJSON_Parse(msg_json);
if(json_processing != NULL)
{
cJSON *state = cJSON_GetObjectItem(json_processing, "state");
cJSON *desired = cJSON_GetObjectItem(state, "desired");
if(desired != NULL)
{
.......................
}
}
else
{
Trace(1,"Error parse json");
}
cJSON_Delete(json_processing);

The rest all works well: cJSON_CreateObject(), cJSON_AddStringToObject(), cJSON_AddItemToObject();
the only problem is parse

hi,
since you have used A9 quite long, what do you think about its performance and stability, connection issue with 2G network and so on.

I want to use it for iOT projects for farm but it is difficult to find review about it. I also find it difficult about its programming since it is not arduino. I got 10 module at home but just testing a few sample code.

thanks
