First time here? Check out the Tour!
for multilink client services Nordic introduced the *_EVT_DISCOVERY_COMPLETE events and the *_c_handles_assign functions. Like the BLE_BAS_C_EVT_DISCOVERY_COMPLETE event and the ble_bas_c_handles_assign function for the Batterie Client Service
What is the procedure for multilink server services like the Batterie Server Service ... (more)

I was able to work around the issue by trying on a Linux distribution. Here is a written guide to the package install and board connect process on Ubuntu 16.04: Warning! the guide is written for a ... (more)
We are performing certification testing for our product. We have nRF52832 chip on the board. We used "radio test" example to perform the test and almost all worked well. Except the RX part of the testing. When we choose ... (more)
For longer than I'd like to admit, I've been trying to make an application on the NRF52832 that relays UART data to a phone. To date, I've:
I am using experimental_ble_app_blinky example. In that NRF_LOG over UART was implemented. I Added some UART code for my use. But after flashing code was not working at all. Printf and NRF_LOG_INFO was not working simultaneously. Then i commented ... (more)
What tools do you need for mass production of nRF52832?Can nRF52832's ibeacon mass production change major and minor?
I'm trying to write unit tests and have arrived at the point to write tests for ble characteristic addition to a service.
To offer some background, I have written a test harness called Yoke that will flash an ... (more)
I would like to detect a change in a pin(
GPIO_IN_NUMBER) and depending on it I would like to trigger a SPI transaction, this should happen through PPI.
So far I have configured my PPI in this way, is ... (more)
I am running example: nrf5-ble-tutorial-advertising on a nRF52-DK. with SDK 11 and s132_nrf52_2.0.0 softdevice. When I flash the code to the nRF52-DK, LED1, LED2, LED3 and LED4 are ON. My Main.c code is:
/** @file * * @defgroup ble_sdk_app_template_main main ...
hi i have a problem with ble app uart.i used nRF5_SDK_12.3.0_d7731ad and Eclipse Mars 2. I had build main.c in hex ble_app_uart\pca10040\s132 . And after that a maked mergehex with s132_nrf52_3.0.0_softdevice.hex.i ... (more)
hi, I found ble_app_multilink_central example under SDK but this is for LED button application.
Is it possible to configure the same example for NUS?
I worrying about data sharing. As Button and led don't share data and it is ... (more)
I am using the nRF52832 in Rigado BMD-301 module. Updated to s132_nrf52_5.0.0 and nRF5_SDK_14.0.0_3bcc1f7, built the ble_app_uart_c without any changes and programmed it on the board using nRFgo Studio. The problem is that i cannot see ... (more)
I am trying to update our application with DFU support but it will not work for me. One of 2 things happens:
I am trying to use ArrayList for EasyDMA along with PPI but I am not sure whether or not I am configuring it properly to be used with the SPI interface.
So far I have set it up as ... (more)
Using SDK 14, nRF52382, used ble_template to develop a custom app.
I have problems with BLE_GATTS_EVT_WRITE not being called. I do not use auth. My custom ble sevice has 3 chars and all are setup like this:
I am trying to communicate with MLX90615 (here) sensor using BMD300. nRF52 DK is used to program the device. I am testing with a sample code which detects any I2C compatible device which is connected to SDA and SCL ... (more)
Is the SoftDevice can Single step debugging，and don't need reset
I would like to make use of an external ADC that is connected to my nRF52832 through SPI & easyDMA,minimizing the use of the CPU (or without using the CPU).
The sampling frequency, when nRF52832 will request a sample ... (more)
I have code running on a nRF52 device, with SoftDevice enabled, based on the example given in this topic:
This runs fine on its own, and produces an 8MHz clock. But if I enable another ... (more)
Working on migrating my application from sdk 12.2 to sdk 14 except for some flash issues most of it seems to be working as before, except I notice this message in jlink:
0> <info> app: Connected 0> <error> ble_gatt ...
Edit: Rephrased the question to make it easier to answer.
I used flash storage to store a couple of variables between resets in a app made from SDK 12.2, now I am attempting to migrate to SDK 14, but ... (more)
I work with gcc on nordic nrf52 SDK13.0.0. I see the post: https://devzone.nordicsemi.com/questi...
But if I try to change the packet in the radio_event_handler in active state, with ble_advdata_set(), I got a HardFault_Handler() interrupt.
I'm building wih Keil MDK-Lite Version 5.24.1 and I just copied the examples for gpiote into my own folder, everything was kept the same (ie copying from C:\Nordic\nRF5_SDK_14.0.0\examples\peripheral\gpiote to C ... (more)
Hi, I'm trying to use nRF52832 by external oscillator(ash7k-32.768KGZ-T). When i use SDK13, i just add clock setting like below.
NRF_CLOCK->LFCLKSRC = (CLOCK_LFCLKSRC_SRC_Xtal << CLOCK_LFCLKSRC_SRC_Pos) | (CLOCK_LFCLKSRC_BYPASS_Enabled << CLOCK_LFCLKSRC_BYPASS_Pos ) | (CLOCK_LFCLKSRC_EXTERNAL_Enabled << CLOCK_LFCLKSRC_EXTERNAL_Pos); NRF_CLOCK->EVENTS_LFCLKSTARTED = 0; NRF_CLOCK->TASKS_LFCLKSTART = 1; while (NRF_CLOCK->EVENTS_LFCLKSTARTED ...
the project has a problem with DMA,the detail is: on the board,NRF52832 and extern chip communication with i2c bus,the chip through a pulse wake up nrf52832,NRF52832 start work,but the wake up frequency of cpu is ... (more)
what is the sending data rate of the sd_ble_gatts_hvx() ,why i use sd_ble_gatts_hvx() send data 600Byte per second, it lost data again . it can be use yes or no ??????????
why it is so Poor experience
why the DFU through OTA is not lost package ， How did you do it
when i use sd_bl_gatts_hvx() send data ,the return value is BLE_ERROR_GATTS_SYS_ATTR_MISSING,how i deal with the error
NRF_SUCCESS Successfully queued a notification or indication for transmission, and optionally updated the attribute value. BLE_ERROR_INVALID_CONN_HANDLE Invalid Connection Handle.
