Hi, I’m working with an nRF52840 DK and trying to use two UARTs simultaneously. I’ve configured UART1 for debugging (console and shell output) and want to use the default...
I am getting the following build errors when working with both DFU (MCUboot) and the file system (FAT FS) together. Errors: D:/ncs/v2.9.0/zephyr/drivers/disk/flashdisk.c:533...
Hi all,
Our company is currently prototyping with the Nordic 91X DK and looking to use both nrf cloud services specifically for using location services whilst also connecting...
nRF54L15 would be used as thread RCP, host processor would use uart to communicate with the rcp. They would behave like a OTBR.
I also need to do device firmware update...
Hi,
We're working on a project using the nRF5340, where we interface an external NAND flash (4096 blocks) to store high-volume sensor data. We are planning to maintain an...
Hi,
We are currently evaluating the NRF9151 for asset tracking using the AT firmware on the NRF9151 evk and an external MCU for the application firmware, emulating the final...
I have a timer that sends BLE data to a central every 5 seconds. The timers starts immediately out of reset. Until I actually pair the devices, the nRF51822 outputs an error...
I have problem to debug when I use softdevice it frezzes. At the moment I debug the program part with out use of softdevice is there any other solution? It the same code with...
Hi all.
I am new in nRF BLE. I am planning to buy an nRF51822 Kit but little bit confused with choosing EK or DK. Actually my plan is after playing with the Native Kits...
I am currently designing a board using the nRF51822 chip and I would like to implement a soft power ON circuit using the low power comparator (LPCOMP).
I understand that...
Hello,
I'm using a code posted on this forum to read ADC input and fill an array with the ADC values but I always get values between 166 and 174, (even if I connect the ADC...
I'm completely out of ideas.
I've been developing a server for some time now based loosely on the ble_app_hrs sample using the 5.2.1 SD. Things have been going reasonably...
After I process some data (command) received by UART fifo module (I have installed handler for APP_UART_DATA_READY) I need to do a short atomic operation of a few instructions...
We have a project where we would like to use a balanced / dipole pcb antenna. As far as the great docs on the site stands, it's all for unbalanced / monopole antennas. Any...
Hi,
In my application I need to control a nrf51822 central device by an external MCU.
Does Nordic provide solutions to control a nrf51822 Cental device (with S120 softdevice...
Is there a register, accessible via the SWD-DP and present across ARM devices, that I can use to distinguish the nRF51822 from other microcontrollers?
Thanks,
-c
I can discover RFduino BLE devices that use the 51822 using the Master Control Panel but cannot with the nRFTemp app. The nRFTemp app scans for but does not find my RFduino...
Hi,
I have nRFStartet Kit, nRF51822DK and EK.
What is nRF2739? I am just following the setup section in nRF51SDK and it says to connect Master Emulator to PC. Is it...
Hello,
I have been attempting to get the watchdog timer working in my project without any success. I have read through all of the watch dog related threads that I could...
The S120 is a pure Central softdevice, and hence it can connect only to other Peripheral devices. Does it means that s120 cannot be used as a peripherial device?
Hello all,
I have been using nrf905 for about 5 years without problems.
now I would like to ask if is there any way to use an external PA? I am not a RF engineer and i...
