lwm2m_client_nrf9160 - Custom Board

[HassanKhan996]

Good day

I am currently trying to a create a lwm2m client to use with my custom board. When I have queue mode enabled and the device is sleeping, I use the lwm2m_send function and get a very high power consumption. I have found that the program hangs before getting this while logging:

[00:19:30.532,806] net_lwm2m_engine: Connected, sock id 0

I have also attributed this to:

zsock_connect(client_ctx->sock_fd, &client_ctx->remote_addr, addr_len)
when the client attempts to re-establish a connection (lwm2m_engine_connection_resume), this function takes a while to complete and causes the high power consumption. For a better understanding, I will post the power consumption while using and not using queue mode:

I have noticed that in queue mode, a registration update is triggered. However, the high power consumption occurs during the above mentioned process after a registration update is triggered. Is there a way that I can avoid this as queue mode is essential for my project.
Thank you in advance
Kind regards,
Hassan

@carlescufi can you suggest how to proceed? Not a bug, wondering if this should go in the Nordic support forums.
