https://devzone.nordicsemi.com/f/nordic-q-a/80580/memory-leak-with-cjson-libraryHi everyone, I&#39;m collecting some data from the adxl362 accelerometer and from the env. sensor and sending them over MQTT. This is the main.c file: And this is the accel.c file where I get data from the accelerometer: Everything worksen-USTelligent Community 13Thu, 14 Oct 2021 08:04:10 GMThttps://devzone.nordicsemi.com/thread/334052?ContentTypeID=1Thu, 14 Oct 2021 08:04:10 GMT137ad170-7792-4731-bb38-c0d22fbe4515:833650c2-fd65-4be8-8494-9b79366187ffJONATHAN LL<p>Hi,<br /><br />How does main.c have access to&nbsp;moving_average_ variabele? The other cJSON data seems to be handled locale in the main.c file.&nbsp;<br /><br />Maybe try to use extern on the moving_avrage variable.&nbsp;<br /><br /><br />Error handling on line 108-109, you don&#39;t seem to check if it actually gets allocated.<br /><br />if (packet == NULL) {<br />LOG_WRN(&quot;Erorr, not enough memory!&quot;);<br />}<br /><br /><br />Could you share the whole project?<br /><br />Can you debug&nbsp;<span>moving_average_</span>x, set a break point there, what is the actual value?<br /><br />Regards,<br />Jonathan</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/333985?ContentTypeID=1Wed, 13 Oct 2021 14:50:23 GMT137ad170-7792-4731-bb38-c0d22fbe4515:61ff4650-e956-437a-8e14-83f720b78fd1JONATHAN LL<p>Hi Giuls,<br /><br />I will look in to this issue you have and come back with an update.<br />Regards,<br />Jonathan</p><div style="clear:both;"></div>
