Hello and Happy new year to everyone, I am working in project with target to use zephyr as base of any freestanding application. Specifically, I would like the developer to have the ability to choose

Hello, I am investigating if the implementation of contiki-ng RPL border router can be useful in zephyr. I am trying to set up the echo client example of zephyr using the overlay-802154.conf file in o

Hello, I am studying this which mentions that the MCUboot is placed to immutable section of flash. How is this implemented? I can not see anywhere information about immutable MCUboot partition.

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

Does zephyr only supports PSK for the DTLS (e.g echo client, lwm2m client). I haven't seen anything about RPK using ECC.

Hello, I have made a device DTS overlay file to create my partitions in flash, so I have 3 different partitions (banks) lets say A, B, C respectively. It seems to work. However, each time I am trying

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.

Update: if I write and read in a function without some condition (i.e button is pressed) works fine. The problem is when the write/read process is taking place to button_pressed callback function.

Hello again, I am following the NVS sample to create my own code in order to write to the NVS filesystem. The idea is to change a uint8 variable in the NVS when the button is pressed. Therefore, when

Perfect. I will prepare the configuration for the contribution. I made the changes you proposed and worked (I set MAX_PACKET_SIZE to 1024). Just to be clear by what do you mean by "OT use mbedTLS inte

Hello, Update: I just want to change the boot address (or slot) before the reboot, without using MCUboot. I am looking on zephyr documentation for a mechanism like this but I can not find any utility.
