I was implementing custom services and characteristics(softdevice:s140, ble) on the nrf52840 dongle, however I couldn't get it to work, even though my code seemed correct...
Hi,
I´m working on a Zigbee-based environment sensor. You can find all related files here: https://github.com/Kampi/BeeLight
Now I have the following scenario: the whole...
Does the nrf54l15 have a register to specify the boot area? Similar to the NRF_UICR->NRFFW of nrf52833.Or does the nrf54l15 have to boot from address 0x00000000?
Hello,
I've been going through the BLE fundamentals course and things are going well. I'm using the nRF5340DK board and SDK version 3.0.2
I've gotten to lesson 3, exercise...
Hi,
I am working on the channel sounding feature on the 54l15 and I want to perform it sequentially between 3 reflectors and one initiator. I realized that after I make...
Hi,
We're at a point in our project where we're working through some regulatory testing for ETSI/FCC certifications with our BLE dongle board (nRF52840 + nRF21540 FEM...
Hi,
I'm using zephyr RTOS.
I'd like to put the cpu System ON Sleep Mode to conserve power.
Then, I'd like to restart the CPU with an interrupt or event from the comparator...
Hi,
I added one more timer. As soon as the timer expires and it runs the event handler, and then advertising stops, and the firmware crashes.
Could someone please tell...
I've recently discovered the power consumption issue with FreeRTOS and SDK12.3:
devzone.nordicsemi.com/.../
So, I am now using SDK12.3 with SDK13.1 FreeRTOS files.

I am using Nordic SDK to program an nRF51822 chip. I want to optimize power consumption as much as possible so I am looking at using the -march gcc flag. The problem is I...
I am using the ble_peripheral template that comes in Nordic SDK 8.1. I setup uart logging and also debugging with the following lines of code:
void assert_nrf_callback...
Hi, We are trying to connect a LED to one of the GPIO of nRF52840, we would like to know how to connect it. Connect it such that the nRF52 GPIO sink current or source current...
Hey, I am using WT51822-S4AT module and want the nrf51822 to connect to phone. I don't have nrf51-dk. I am using stm32f0-discovery kit. Can it be done using that kit? I searched...
Seems battery reads are not consistent in thngy52 2.1.0 software.
Observed a ~4% difference in the consequent battery reads. This difference is high (upto ~40%) if the thingy...
In the recent past, I used a SoC in which GPIOs could be configured as "open drain", that is in which there is an internal transistor where the SOURCE is grounded, the DRAIN...
Hey,
I'm using nRF as a SPI slave with a Raspberry Pi. I'm seeing that even at ~3MHz SPI frequency, my first byte transferred gets corrupted. I have a test setup where...
I am using nrf52 with s132 and armgcc
As I add functionality to the code I get to a stage where it fails. Linker runs OK but the result fails to execute.
The observable...
I am currently working on a BLE beacon project on nRF51822. Using SDK 12.3.0 and s130. The device has to advertise URL, advertising name and output power level. And these...
I am trying to control a current measurement chip (DDC114) that works with a protocol that is close (enough) to SPI. It has 2 channels, s.t. it can be read out and integrating...
