cJSON_Parse() failure

[Lars M]

Hi,

I am sending data from AWS and run it through cJSON_Parse(). If the message is just a little bigger than 1000 bytes, I will get the message "cJSON Parse failure". Debugging the code, function cJSON_ParseWithLengthOpts() will be the one that fails. I guess it likely has to do with lack of memory. The rows

item = cJSON_New_Item(&global_hooks);
if (item == NULL) /* memory fail */
{
    goto fail;
}

will not go to fail, but the result of the next rows will:

if (!parse_value(item, buffer_skip_whitespace(skip_utf8_bom(&buffer))))
{
    /* parse failure. ep is set. */
    goto fail;
}

Is it lack of memory that causes this? If so, is it possible to increase available memory? I have tested to increase
CONFIG_HEAP_MEM_POOL_SIZE
CONFIG_MAIN_STACK_SIZE
CONFIG_SYSTEM_WORKQUEUE_STACK_SIZE
but it doesn't help.

Best regards,
Lars

Hello again,

Sorry for the delay caused by the holiday period.

Could you tell me which NCS version are you running?

Are you calling cJSON_Init() before using cJSON? This is needed in order for cJSON to use the OS heap memory pool.

Best regards,

Michal

Hi Michal,

I am using NCS 2.1.0.

Best regards,

Thank you for the information.

What about running cJSON_Init() before using cJSON?

Best regards,

Yes, I run cJSON_Init() in the beginning of my program.

Best regards,
