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

I realize I mentioned the need to set the pin low and that code above is attempting to set the pin high. If I just start the board without this code, the pin is measured low on my oscilloscope even wi

Greetings, I'm working on adding a board to Zephyr. I'm attempting to use a board.c file to configure GPIO pins as output and initialize them low on start-up. I've attempted to follow existing boards,

#gpio #nrf52840 #sys_init

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

Hi Jurgens, have you tried to connect to Azure using for example qemu, this way we could rule out issues in modem config? I did not spot anything obviously wrong in your main.c, but as you have notice

Hi everyone, I am really struggling to get the mqtt_azure sample working. It just does not want to connect to IoT hub. Thank you once again for your assistance @Jukka. Can anyone help me to get this w

Hi Jukka, I only had to add a board overlay for my nRF52840 in order to get the gsm_modem sample up and running. Drivers specifically for the Quectell BG 96 and Sara 412 are available in Zephyr. I act

Hi Petrus, Did you need to do any changes to generic gsm modem in order to get the BG96 or SARA modem working. I do not have these modems, so would be interested to know if they worked ok without any

Hi, Zephyr community. I am trying to add Azure MQTT functionality to my project. I am using an nRF52840 with a Quectel BG96/Sara R412M-02B. I would also like to use the modem functionality to communic

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

Hi Leo, Zephyr seems to support the nRF52840 Feather Express, but not the Feather Sense: https://docs.zephyrproject.org/latest/boards/arm/adafruit_feather_nrf52840/doc/index.html This is the right pla

Hello Zephyr team! I have a question about board support and I also need your help building an example project. 1) Does Zephyr support the board below? How would I go about using its sensors? https://

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
