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 am interested in the S130 ability to hold 3 central -> peripheral links over BLE, and am looking for some evidence that this has been accomplished with extremely low-power...
I'm trying to implement channel scanning in our nrf24lu1p based USB dongle.
I'm following the specs and basically loop though each channel ;

Looks like there is an error in the nrf_drv_gpiote_common.h :
#define INTERRUPT_PRIORITY_VALIDATION(pri) STATIC_ASSERT(((pri > 2) && (pri < 4)) || ((pri > 5) && (pri <...
Hi guys,
So as I'm migrating from SDK10 to SDK12 I've noted that the app_pwm module is consuming more power then expected while disabled ~300uA. After initialization, I...
Platform: nRF52-DK using SDK12.1.0 and S132
Summary: Using nrf_log module from SDK along with RTT by setting NRF_LOG_BACKEND_SERIAL_USES_RTT flag causes nrf_log_serial...
For example, in SDK11, the file:
components/softdevice/s130/toolchain/armgcc/armgcc_s130_nrf51822_xxaa.ld
Contains:

Not a question, but a big thank you to Nordic Tech Support (Kristin) who reviewed our nRF24 design several times until we got it right :)
Implementing the recommendations...
Hi,
I am creating the first prototype for my BLE product and for now I used the suggested layout from the datasheet, but I am kind suspicious of that layout it seems very...
I follow the example, as below
nRF5_SDK_12.1.0_0d23e2a\examples\peripheral\flashwrite
but I only get some error, can not get anything, and the ble is unconnected.
Hi there. I'm making a sensor system which is intended to measure an ADC value, and send it using the Heart Rate Sensor template. To make this, I've rebuilt the ble_app_hrs...
Hi
Does the newly released nRF52840 chip have pins on the side, corresponding to the "outer ring" (A8-23, AD2-23, B1-W1, ...) pins on the underside of the chip, like this...
hello i am interfacing i2c sensor mma8452 with nrf51 dk. my function is

I have to sample 3 differential channels periodically. Should I calibrate SAADC for each channel individually? Unfortunately, "nRF52832 - Product Specification v1.0" doesn...
Update 2016-Mar-29: I used SDK v10 along with SoftDevice S110 v8 when I run the experiments described in this question.
Update 2016-Mar-30: Upload source code of the modified...
In order to perform dfu to softdevice S132 v3 sdk12 (secure bootloader) from sdk11 softdevice S132 v2 (legacy bootloader).I've change the legacy bootloader as it it says here...
