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 am using internal ADC to sample 2 (sometimes 3) channels on about 333Hz frequency.
What I do is:
set channel 1 as input (always two-thirds prescaling, VBG reference...
Hi,
I want to debug nrf51822 beacon using DK.I made the necessary connections between dk and beacon.I managed to flash the beacon using nrfgoStudio , but if I want to do...
I have the following code, it's pretty bare in terms of its functionality:
#include <stdint.h>
extern "C"
{
#include "nrf_delay.h"
}
#include "gazell.h"

I succeeded to made the BLE DFU example of SDK 8(bootloader\pca10028\dual_bank_ble_s110) with softDevice 8 working on PCA10001.
Now I want to try DFU over UART.
I follow...
Hi,
Sorry if these are silly questions but I've tried some searchings and still cannot figure out the answers for the questions below
What is GATT Server Context...
Hi,
I wrote some code that writes to the flash perfectly when BLE is not enabled but when it is enabled, some of the data are correct while others are either missing or...
Hello folks, I have modified the SPI Master Loop example from the package so that I could communicate with the ADXL 345 accelerometer. I use the "spi_master_send_recv()" function...
Hello,
I'm trying to retrieve data from a nrf51822-based board that supports the BLE NUS sevice (using the ble_nus Library provided for the uart communication example,...
Hello!
I've just started using the nRF51 dongles (currently having 5 of them) and I would like to test the GitHub mesh protocol . Excuse my lack of experience, but I am...
Hi,
I'm trying to load the ble_app_beacon application under C:\Nordic Semiconductor\nRF51822 Beacon v1.1.0\Source Code\nrf51_beacon\ble_app_beacon\pca20006\s110\arm_build...
Hi there,
Is there any way to resolve a BLE_GAP_ADDR_TYPE_RANDOM_PRIVATE_RESOLVABLE address without using whitelist advertising? If not, I guess I should implement the...
Hi,
As question "custom serial wire debug" date Jan 14 '14, I'm also interested in programming the chip from an other embedded chip (would fit our production process verry...
Hi,
We're looking for a low-latency 2.4GHz solution (not BLE) and the nRF51822 is oft-quoted as providing low latency, but what are the typical ms figures we could achieve...
Hi All,
I am using the nrf_udp_client example project in IoT SDK as the code base for testing the UDP communication.
For network topology, the nrf51-DK plays the role...
