Hello all,
in my previous question (Switch between applications (multiple services.h)) I got the advice to merge my two services into one service, including a HID over...
I am trying to create an nRF8001 based application that will broadcast battery levels (pipes broadcast, set), and give out temperature data (pipe indicate - TX_ACK) to connected...
Hi,
I'm using redbearlab's nrf51822 board. It is a arduino compatible board and hence it is using 0,1 (mapped to 9 and 11 for nrf51822). How do I make printf print to this...
An external PA/LNA is used to extend range of nRF51822, and S110 is used for BLE, How to switch between PA and LNA? and how to disable PA/LNA when there isn't transceiving...
Hi...
Can anybody help me to run ble_peripheral example (ble_app_hrs for S130). I have build and load the code successfully but cant see the advertisement. But while debugging...
I am working with the nRF8001, and I'd like to create a services.h file that will let me broadcast battery level and as well as allow temperature to be read by a peer.

Hi We have an application where we what to read i2c sensor data over the air to an iPhone. We've taken ble_app_uart_S130 project and grafted in some twi_hardware code. There...
I'm not sure how often the Cortex-M4(F) design from ARM is updated, but what is version used in Nordic nRF52810/52832 devices? I want to know what ARM documentation version...
I can successfully download an image using nrfutil dfu serial when I use a test image (compiling the bootloader with the Nordic default public key) and the application starts...
Hi,
My requirement is to validate the PCA10040 dev board with a different set of UART pins. I have tried the following steps, but as soon as I start the firmware, it crashes...
Hello, I am new to BLE development and RF design. I've been doing as much reading as I can about RF design rules for PCB's, antenna performance, etc. Yet I am still uncertain...
I am trying to get a BMX160 working over SPI. I was following this post to make this code using the SPI example from the SDK as a basis. I am using SDK 15.3 with a nRF52840...
The app is foreground -> I am very easily connected with BLE device.
The app is in the background -> I get the callback and connect with the BLE device
The app is removed...
Hello.
I'm trying to get the example bootloader Segger project (secure_bootloader_ble_s132_pca10040) running on a custom board I have that uses the nRF52832 as its core...
I am working on nRF9160 and i found that when i change prj.conf, i need to rebuild code. if rebuild is not done(only build is done), changes made in prj.conf does not comes...
Hi
I'm currently evaluating the possibility of using nRF5340 in an upcoming project. As the chip is very new it's easy to understand that all specifications are not yet...
Hello, I am using nRF SDK for Mesh 3.1 and nRF52940 SoC. I have two nodes in my network which both act as a client and a server. Both of them subscribes and publishes to same...
Hi,
I am working with ANT bpwr tx profile and trying to implement HX711 and TWI sensor to it. TWI sensor is already working, but when I add library for HX711 from and start...
Hello,
It would be nice if the HVN tx complete event structure had the attribute handle of the characteristic that was just notified. This is already done for writes and...
Hey guys,
I'm working with the Laird DVK-BL652 and the Nordic SDK v.14.2.0 with Eclipse (Kepler) and try the example "SPI Master". I didn't modify this example but after...
Test Setup:
SD 6.1.0
SDK 15.2.0

Central: iOS 13.1
Central is connected to two peripherals, each peripheral is sending 50 pkt/s, each packet...
Hi,
We have a nrf51822 based custom board with no button, we use accelerometer tap detection to wake up the system. Currently there is no software protection for the battery...
