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
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
I just want to create a custom service with a characteristic, which sends "n" (upto 200) bytes at same time and this bytes are are written to a SD card via SPI
So...
Hi, I have been using the nRF8001 Arduino SDK with nRF8001 chip. I wanted to set the data for the different services I'm using and thought I would go ahead and use the services...
Dear sir
Now, I am trying multi-link examples at SDK5.2.0 S120 example. I found s120 central only can receive one byte data from s110 multi-link peripheral. Could we modify...

Hello,
I have some problem with NRF24L01+. I'm trying to make bidirectional connection between two devices with this chip. When I'm sending payload with ACK, TX_DS interrupt...
Dear nRF Gurus,
I made a board with nRF8001 and PIC24F to stream some sensor data to a computer. I have also developed a simple Mac app to communicate with my board. (similar...
Hello,
I am redoing some experiments with 2 pca10001 and the ble_hrs example (with s110, s120) !
What I would like to do is that the s120 side displays the power received...
I'm designing a small board with an nRF51822. I'd like to use a 'meander' PCB antenna similar to the ones on the Evaluation Kit and 'dongle'. Is there a definitive guide ...
I'm trying without much success to write something fairly simple. Basically connect a signal to a pin, and run a function whenever that pin changes state. What's confusing...
Hello all,
I am debugging my nrf51822 application using evaluation board and keil debugger. I have uncommented the ble_debug_assert_handler in app_error_handler. When error...
