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
1) semaphore to do this?
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,
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...
I'm implementing an Android 4.3 app which uses an nRF51822 and the BLE proximity profile. I have the following as starting points for the app code:
The BLE sample...
I can't seem to find the required current of NVMC doing erase and write. The product spec has only timings but not more. Could someone from Nordic provide some figures? Experimental...
Hi,
I have a C# app connecting to 51822 devices, doing data/firmware download. When I try to send erase page command (before write), erase works, but there is a disconnect;...
Should we keep track of this by monitoring the write events or poll the gatts value via the softdevice?
It looks like it's faster (+shorter = less consumption) to monitor...
Over the past few months I have worked extensively on a few different projects that all utilize the nRF51422. In some recent debugging of GPIO issues (both relating to SENSE...
As the title says, I am wondering when the new SDK will be released to support the nRF51822 hardware revision. It looks like the latest (v4.4.1) doesn't have anything new...

Hi, i'm experimenting RTC1 using the app_timer module (not using S110 soft device), and i find some problems onRTC prescaler. If i set values as stated in the datasheet, for...
Hi,
I am trying to run several applications sequentially on the nRF51822.
I have another microcontroller controlling the nRF51822 by SPI.
I init the stack, the services...
Hi, I'm just wondering if there's a reason that the example code is always initializing all structures through functions. Has it something to do with sleep mode and RAM retention...
