Re: LWM2M client to nrf582540-DK #nrf52840 #networking

Thanks Robert, with your help I managed to make the OTBR work (I can make a documentation as contribution for the project if you are interested). Although, the device is registered to the leshan server as it should, I have two problems. The first one is that I can not change the CONFIG_LWM2M_COAP_BLOCK_SIZE to 64 (or 128) because I am getting the following error <err> net_lwm2m_rd_client: Registration err: -12 which I saw in API that corresponds to * Not enough core */. The second problem is that I can not build the lwm2m sample when I use the overlay-dtls.conf to enable communication over DTLS in the openthread network. The description of error is that error: Aborting due to Kconfig warnings the warnings are about the NET_IF_UNICAST_IPV4_ADDR_COUNT, NET_IF_MCAST_IPV4_ADDR_COUNT, TEST_RANDOM_GENERATOR and NET_SOCKETS_ENABLE_DTLS parameteres. I tried to comment in some of them but again I have problems. My build command is west build -p auto -b nrf52840dk_nrf52840 samples/net/lwm2m_client/ -d build_lwm2m -- -DCONF_FILE="prj.conf overlay-ot.conf overlay-dtls.conf"

Do you have any ideas?
