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.

I am using SDK 15.0 with the Nordic NRF52840 development board. I wrote my own custom bootloader using CDC ACM as the transport. I am using app_usbd_cdc_acm_read_any to read...
Hello All,
Is there any already available example of OLED display interfacing with nRF52DK, pca10040, SDK 14.1 in Segger Embedded studio?
I am working on a project...
Hi,
I want to measure the time of two signals to calculate the speed and sent the data with BLE. I find the SD effect the GPIOTE_interrupt sometimes, when I try to use GPIOTE...
I an trying to locate and download some programming examples. For instance the BLE Blinky application
ble_app_blinky_c says it is in the EXAMPLE FOLDER, no matter where...
Our project uses nRF52832, and the bluetooth connection has two modes as follows:
one is low-power standby mode connection interval=1000ms;
One is data transmission mode...
We have recently ported our application from SDK 12.2 to SDK 14.2. The application is very power sensitive and uses a high connection interval and slave latency to minimise...
We have a project running based on the SDK 14.1 on a nRF52DK with S132 5.0. The used bootloader works as expected and also an update of the bootloader works properly.
After...
