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

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,
My behavior is as follows
Turn on my device(use 51422) and advertising(2 Service and 3 Characteristic)

Hello:
I used analog IIC write MPU6050. Again after power download programs, mpu6050 can run up there ACK response. But the debug will not run. Simulation IIC because no...
Hi,
I want to implement simple module:
gpiote event on pin change (around 6.7MHz signal)
Route gpiote event through PPI to increment counter

According to the documentation, the function sd_ble_gatts_exchange_mtu_reply() can return NRF_ERROR_BUSY , which would require the application to somehow defer the call to...
Hi,
I am attempting to run the examples of BLE HRS C and BLE HRS Peripherals from the SDK. Getting to the connected state works (discovery and notifications as well) just...
I noticed that the ram setting in this example is from 0x20003440, this means only less than 1KB is for application. But the example in sdk 12.1 the ram is from 20002078....
We want to use IoT SDK where two or more nRF52 chips would talk to each other via 6lowpan, in that case is the ble enabled router necessary for such communication?
I have an nrf51822AC chip connected to another ARM based processor which provides a CAN interface. The two are connected via the UART and we are using the ble_connectivity...
Hi, in the current project I'm working on, I need to develop an Eddystone beacon with UID and TLM frames configured by default. Based on the experimental_eddystone example...
Hi, Nordic
I need write some information to flash, then power off and power on, nRF52 still can read previous information. But now, nRF52 can not read, maybe ESB is still...
Hi,
I'm having issues with my MPU6050 sensor. I'm trying to get yaw, pitch and roll raw sensor values from MPU6050 sensor using DMP on MBED platform but without success...
I have just read nRF52840 Engineering A Errata v1.0, it looks like nRF52840 is like swiss cheese.
When can we expect some solid version of nRF52840 chip on the market?
Hi DevZone
Does the SWF switch at the PCA10040 automatically switch to the antenna I have put on my connection probe? ( www.digikey.com/.../1775923)
Thanks in advance...
Hello,
i have read if not all posts about writing to FLASH while using BLE. But could not find the desirable method.
What i would like to do is to write to flash from...
