NRF_ERROR_NO_MEM when sending message from client to multiple servers.

[him]

Hi Nordic,

I have added 20 client elements on a client node to control 20 server nodes(Light_Switch example). While sending an acknowledged message to all servers on a button press it sends a message to only 4 servers and gives NRF_ERROR_NO_MEM error, on further debugging I found that this error is generated from core_tx_packet_alloc().

Mesh SDK:- 4.2.0

NRF SDK:- 16.0.0

Example used:- Light_switch_client and light_switch_server

Thanks,

Himanshu

Have you looked at the documentation for that function? It should tell you under what circumstances it will return that error.

Sounds like you need to adjust your memory settings ...

Hi Awneil,

Thanks for the quick response.

Can you guide or provide me some links for the documents related to the issue.

Thanks

Use 'Go To Declaration' (not definition) to find the prototype in its header file. The documentation is there as the function comment.

All other documentation is just auto-generated from that (Doxygen)

The problem is resolved but I don't know if this is the best solution for my issue

increased the buffer size of CORE_TX_QUEUE_BUFFER_SIZE_ORIGINATOR
