I solved the issue. The size should be multiple of 4096 (sector size). An other problem that I am facing is that when I run the lwm2m-client over openthread and the last address of the program is 0x59

Hi all, I would like to ask you if I can change the lwm2m observer period. There is enough delay (some seconds), after calling lwm2m_engine_set_u8("5/0/3", STATE_IDLE) until the server get informed.
