To be able to upgrade FW through UART, a bootloader for nrf51822 is required in my project. I have tried out the example bootloader in SDK. But this example is using softdevice...
I followed the forum posts and nan-29 to get eclipse 4.3.2 to successfully connect to JLinkGDBServer via a Segger J-Link EDU on Ubuntu Linux.
I can start the GDB server...
I'm using Softedevice 6.0.0 and SDK 5.2. and Keil 4.7.
I Modified bootloader project so it compiles with both ble and hci transports. Currently I use button_0 and button_1...
I am working on the proj that needed 2 MCU and nrf51822 work as slave.
I would like to know any ref on how to firmware upgrade on board without external tool?
We're looking for a Nordic nRF51822 based low profile/small USB dongle that we can use for our iBeacon software.
It would need to come complete with casing and the ability...
Hi all,
i want to establish connection between two threads in cmsis-rtos, can i use

2)message queue should be used or any other ipcs can be...
Hi,
I have two CPU in our product. (STM32F2 and Nordic nrf51422).
I use serialization function to link those two CPU(refer to ble_s110_serialization sample)
But I find...
Hi,
Both examples were built failed in Keil due to exceeding 32K trial limitation. Is there any way to reduce the size? Or any suggestion?
Platform: nRF52DK

Take a look at these screenshots. With the trigger enabled, the average current consumption is reported at 13.21uA. With the trigger disabled , the average current consumption...
Dear Nordic,
I want to know if it is possible to send asynchronous data type from a slave node to a master node (master node would be in continuous scanning mode). Reading...
Here is my problem. I want to disable uart when there is no data coming into MCU.
I used IO LotoHi event to enable uart Rx. After finish data receiving, I disable Uart.

I've modded the PCA10040 DK for current measurement with an ampere-meter (TTi 1604), using a program which turns an LED on and off every 5 seconds. The measured current stays...
I am using an LG G5 and my co worker let me use a google pixel. I tried using the s132 softdevice along with the BLE UART example code from 12.2.0, I get the device is not...
I'm aware of GATT's Profile, Service and Characteristic.
And also, for GATT_Server, GATT_Client it can be Central or Peripheral. (As I manually set it.)
And also, the...
