Hello,
I established a connection between my central and peripheral module. Now i want to write characteristic value on peripheral. I tried with sd_ble_gattc_write function...
I am using the NRF24l01 for my products and looking to buy in bulk(100-1000). Now I know where to buy the just the IC but antenna design is a hard point to break right now...
Hi, my friend,
I've been with nrf905. I use a 16-bit CRC check.
But I encountered problems in use:
1.Nrf905 16-bit CRC check format is CRC-16(IBM):X16+X15+X2+1 or other...
I have two custom PCBs, each of which has a microcontroller and an nrf24L01+. Everything related to the transceiver in the designs are complete duplicates (with the exception...
Hello,
I've built a small BLE-device based on the nrf8001.
With my Iphone I can discover this device and I am able to connect to it and listen to notifications of the...
Our pcb is used for gps location data. We have a nrf24L01 nordic chip as the micro process or between the gps module and wireless module (2G). Our engineer needs to capture...
Hey folks,
I'm trying to modify the SPI Master loop back example into a 4 line SPI Master_Slave program. Whenever I change the Tx_Buffer_lenght from 10 to lsome other numbers...
I'm upgrading a project from SDK 15 to SDK 16. Previously in my gap parameters init I had this code
This works fine for seeing the peripheral and operating it as a UART...
I wasn't sure which product to put in. I am looking for a BLE discovery tool for EEG devices -- particularly the Muse 2 Headband. Which of Nordic's software should I use for...
Hi,
In our project, we are using a small RTOS to switch between simple tasks and set MPU. We would like to run all task in unprivileged mode, but some Nordic SDK libraries...
Hi everyone,
I have written a code that sends data over BLE notifications (IMU data). It works great so far and now I want to read the analog values from eight force sensors...
Hi everyone,
I have a problem I can't sort out. My program runs fine indefinitely if I set one variable in a function at one point but if I don't do that, the program, or...
Hello,
We have around 700 product in the field based on the Simblee BLE module, which was discontinued 1+ year ago. Application was developed using Simblee's proprietary...
Hello,
I need to develop two applications for nRF51822 using SES version 4.18 (macOS). One is a DFU bootloader. The other is an application based on the ble_app_uart (ble_peripheral...
Hello,
I am trying to run the BLE Thread Dynamic Template example on a nRF52840 dongle. I'm using Segger Embedded Studio to generate an hex file. I flash the hex file to...
Hello,
During testing we found that whenever in system off mode, the CPU wakes from VBUS rising. As expected. We then do a vibration to notify the user the USB cable was...
When integrating nRF Mesh SDK 4.1 with nRF SDK 16 I got an error in runtime.
The call sequence:
mesh_init() -> mesh_stack_init() -> nrf_mesh_init() -> mesh_config_init...
Hi all,
I have really strange behavior with Sesgger SES. I'm working on Linux Kubuntu lastest version.

I am trying to use C++ with an nRF5 board, but I'm running into issues with the MDK, IAR (v8.40.2), and C++. When I try to include "nrfx_gpiote.h" in a .cpp file, I get the...
Hi,
I have a basic setup consisting of a time-slotted transmitter and receiver so that I can experiment with the raw coded and uncoded modes, exploring all the NRF_RADIO...
If you're working on a product that requires you to show and translate GATT Attribute (Service, Characteristic and/or Descriptor) UUIDs to Strings to the user, it's likely...
Hi, I want to create a mesh network with two nrf52840 dongles. To programming them I used the light-switch example from SDK Mesh v4.0.0 following the steps in this tutorial...
