Hi,

4096 is quite high, you will probably be OK with a lower value.

Please note that this is a dedicated heap for the at_monitor library, and is not a part of the generic system heap (which is configured with CONFIG_HEAP_MEM_POOL_SIZE).

You can read more about the at_monitor here: https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/libraries/modem/at_monitor.html

Kind regards,

Håkon

Thanks, add CONFIG_AT_MONITOR_HEAP_SIZE=4096 to prj.conf solved the issue.

Where can I find more information about this, it was 256 and now 4096 but why would I not make it 8192 or 1024?

Hi,

The AT monitor has its own dedicated heap. Could you try increasing "CONFIG_AT_MONITOR_HEAP_SIZE" and see if helps?

Kind regards,

Håkon
