In the examples directory of the NRF52-SDK are there any examples that demonstrate a peripheral sending advertising packets at a very frequent rate?
I'm working on an UART application which uses experimental_bootloader_secure_serial bootloader. I've done a similar thing before with SDK-11 (though not a secure DFU) and after getting through building a secure bootloader, signing, etc. I was able to ... (more)
Have been using Keil MDK Lite in the past, in a Win VM. Larger code (over 32KB) plus the convenience of running without a VM layer have led me to switch to NetBeans/gcc/gdb directly on my MacBook ... (more)
I'm using a nRF52-DK for a while, but now I made a bad misstake: overwrote the interface firmware. I pressed accidentally the RESET button and flashed a wrong hex file. Now it does nothing, no blinking LED ... (more)
I am finding that the RTT Viewer is very unreliable at changing colour when sent commands from two different nRF52-DK boards. The text is coming out correctly, but the colours only change intermittently. I've tried dropping the ... (more)
Hey, I'm just wondering how to add a UUID to the blinky example peripheral?
I want something like the heart rate sensor where its advertising BLE_Heart_rate_sensor. I'd like to make the blinky advertise BLE_blinky
hello, I am using nrf52 dk. I am doing a project that uart send the adc data through bluetooth to nRF UART v2.0 app for every 10msec. but when i am transmitting the data the bluetooth connectivity was lost ... (more)
hello i am new to spi, i am doing project on 3 wire spi interface. I am using 3 wire interface as Sclk,ssn,MOSI pins only , I am not using MISO pin .I am tested spi example code but ... (more)
Is nrf52 support 3 wire spi interface? I am using AD9837 3-wire spi module act as slave and nrf52 dk act as master. I am using SCLK, SSn(i.e.,Fsync) & MOSI pins only.I want send a commands from ... (more)
I have the board PCA10040 (nRF52 DK).
I designed two different programs:
Hi everyone, I need to know the gain of the BT antenna integrated in the DK for nRF52. Can anyone help?
We have received few nRF52840 preview DK. And one among them has a white sticker label which says 2016.49 and all others have 2017.14.
Should we be using the ones with 2017.14 (assuming this to be latest)?
hello,I am testing twi scanner example of nrf52dk.I want to read slave address, the sda & scl pins are 26 & 27 respectively. I am connected PCA9536 module as slave & address of that module is 0x41.I want to read ... (more)
I am a hardware designer. I have little knowledge about firmware or software. Now I want to apply the nRF52832 to an ultra-low power application as a beacon.
I am testing the nRF52-DK using the original code of "nRF5_SDK_13 ... (more)
Hi, I'm trying to change ad packets in the blinky example. I want to be able to keep blinking but change the ad packs (don't know if this make sense, but main goal is to change the ad ... (more)
Hey, I have my nrf 52 dk. I have soft device v3 on my nrf 52.
I was doing a blinky test with two boards (one central and one peripheral)
I was just wondering how to change the advertisement packet ... (more)
We followed the instructions for the beacon example for nrf 52 dk.
Multiple attempts to change and reset the board, there was no change in the ad packet.
Can someone help?

hello,i am using nrf52 dk, & am working on bluetooth uart & looking for data is send from mobile to nrf52 dk board. i am having examples of data is sending from board to mobile nrf Tool app. But i want ... (more)
I am using a nRF52-DK board to receive data from the USB port using Serial, and transmitting it using ESB to a second board. If I use either Serial or ESB individually, it works fine. I have a ... (more)
We have been using the DFU that came with the sdk 12.1 with a modification (essentially removing the button from the DFU code). We currently send an application command that will tell the code to 'jump' to the bootloader ... (more)
Hi, I develop application on MBED platform with NRF52-DK. I figure out that pin "logic" on this board is interchanged. For example. I have LED connected to some pin. When I set this pin high (set 1) then LED light ... (more)
Edit: The code posted below works on the 96x96 3V(LS013B4DN04) variant of the display, I still have no idea why it doesn't work on LS044Q7DH01, but I'm guessing it doesnt have much to do with the nordic ... (more)
Can I interact with the internal device of the nRF52 DK (PCA10040) while an other nRF52 connected through the P20 (or P19) connector? The JLink tool has a "device" command but I don't known if it can be ... (more)
I have a program which uses two timers to flash an LED, alternating between flashing once every 5s for 15s, then once every 0.25s for 15s.
If I run this on the nRF52-DK with the external LFCLK, it works ... (more)
Some of you may be using the ARM compiler that Nordic provides with SDK 13.0. I was not able to install it on my PC as it does not want to install since it sees another other ARM MDK ... (more)
I have followed a couple of the posts on the devzone on how to increase the MTU and add the DLE support such as this.
However, whenever I send over 20 bytes of data I get an "app_error_fault".
I started working with NRF52-dk. I develop with GCC compiler and mbed SDK (debugging with OpenOCD and GDB). On download (tools) page I see "nRF5x-OB-mbed-IF" with description: "mbed Interface MCU Firmware for on-board debugger for nRF5x Development Tools"
Why do ... (more)
I am very curious to know about difference between revision v1.1.0 and v1.1.1 of nRF52 DK.
Following III. Example code and Enabling whitelisting, I try to connect to the "nRF52 DK" board with a whitelist (Android BLE device address), but I've never connected to the board.(using nRF52 DK, S132-SD-v2 & nRF5_SDK_11.0.0_89a8197)
