Hello,
I'm using the nrf51422 with 210 softdevice.
I'm trying to figure out a way for the receiving slave device to go to sleep when away from the master, but to wake...
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!
Can you please recommend a LDO IC for a USB/Li-polymer Battery power for the nRf51822 please? The LDO needs to drive the nRf51822 and a couple of sensors such as Gyro...
I'm trying to get the ble_app_hrs example working in Eclipse, but the stack pointer is not setup correctly. It's at the start of the RAM (0x20000000), and therefore it already...
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...
