Hello, I use nrf52840-dk as central_hr and nrf52833-dk as peripheral_hr, examples from NRF Connect SDK. I want to read two or more values using bt_gatt_read(). Code: dis->read_params.func = gatt_read_

Hi I want to do the OTA of my nrf52840 based peripheral device through nrf52840(Bluetooth: HCI UART) based Linux gateway. Below is the setup of my project. I know I can perform the OTA of the peripher

Thanks Erik for the pointer. There was a race issue in initializing the pin before the driver was ready. I changed from SYS_INIT(board_init, POST_KERNEL, CONFIG_KERNEL_INIT_PRIORITY_DEFAULT); to SYS_I

With a 5.10.11 linux kernel and bluez-5.55, setting PHY in btmgmt still doesn't work due to a bug in the kernel. You can easily work around that by using hcitool: # set default phy to encoded hcitool

Hi Jukka, Thank you for your assistance. My MQTT client using GSM modem is now working. Regards, Jurgens

I have an application for the nrf52840dk_nrf52840 board where I am using printf() to print some messages. All works most of the time and the messages are shown correctly on my serial console. However,

Hi Leo, The Adafruit Sense is much like the Arduino Sense, both use the nRF52840 but use a modified bootloader. They have been designed to work with the Arduino platform. Luckily work porting the Ardu

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

In general, that's left as an exercise for the user, as far as I know. "Nikos Karamolegkos via lists.zephyrproject.org" <nkaram=ics.forth.gr@...> writes:

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, probably a very simple question. How do I get in my C code the MAC address which is printed on the nrf52840 dongle? Thanks Marcel

Hi Nikos, The Cryptocell requires proprietary software that is not part of Zephyr. If you’d like to use the Cryptocell I recommend you take a look at Nordic’s Zephyr-based SDK, the nRF Connect SDK: ht

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.

Are you in interruption context when trying to read/write in the callback ? I doubt this is a good idea to access a filesystem from such place... (may sleep, may block...) You should defer the read/wr

@Josh Can you give some insight, how you requested Data Length Extension? I can not find any documentation how to do this. I was able to enable to do it manually through the nRF Connect Tool, but need

Hi, there is net_if_ipv4_addr_add() function that can be used to add an IPv4 address to the network interface at runtime. Cheers, Jukka

Thank you Jukka for your reply. I think I will stay with the nrf52840 dk. If there is no other suggestion

Good afternoon, I'm a zephyr newbie, trying to implement it into an IoT project! I'm aware that there is already a driver for the MX25 flash memory device in the nrf's dev kit, but I wasn't able to im
