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 there!
i'm struggling with the problem about using i2c with IoT SDK.
my project is about transferring sensor data (i2c) through ipv6 over ble , so i used the IoT softdevice...
I'm considering purchasing a nrf51 sniffer USB dongle. I believe I can use this to sniff beacon packets and with wireshark view the packet internals, data, channel number...
Hi
I tried to flash the softdevice with nrfprog, but it does not work. Even with nRFgoStudio it does not work.But with IAR I can program an example of the SDK (without...
Hello, all
I have a problem with ble data exchanging.
I have programmed an application which controls servo motors through phone application.
At the connection, ble...
Hi,
I am trying to use the SAADC to periodically sample an input from AIN0 and send the resultant data over a BLE link to a phone. Going through the forums I saw that the...
Hi,
I am trying to debug the blinky example project on the nRF52 development kit.
I have followed the following tutorial: devzone.nordicsemi.com/.../

I'm in the process of designing a circuit that requires Bluetooth. So instead of having a separate chip for Bluetooth and processing, I decided to use a Nordic Semiconductor...
Classic C documentation issue. Are the values that are passed by pointer (p_peer_address and p_whitelist) to sd_ble_gap_adv_start() copied into that function, or do they need...
I'm trying to read the 32-bit value of TIMER1, but it seems the value I read is always 16-bit value. When I debug the value is never above 0xFFFF.
snippet from nrf_drv_config...
The peripheral is actually a dual-mode device, with BLE being a peripheral device.
I can connect to this device and discover the GATT services with the nRF Connect iPhone...
What is the minimum and max value that the NRF_RADIO->TXPOWER register can get set to? The datasheet it takes a signed 8 bit for the setting, but what happens if you set it...
Hello,
I am trying to read data from nRF51422 ADC using SDK51 PCA10028 board downloaded with S130. I tried one of existing ADC with Softdevice examples, it seems to work...
I have meander antenna design on my board with matching network(similar to PCA10031).
Since I don't have access to VNA or Spectrum Analyzer for tuning antenna, I am tuning...
