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 am designing a system that will include an nRF905 transceiver. How accurate should the nRF905 oscillator frequency be for each receiver/transmitter in order to ensure...
Hi all.
Knows anyone someone who use this module with power amplifier ??
Rf module nRF24L01+PA+LNA . I test it .. but still have same distance like module with no PA .....
I'm working on designing a very small footprint PCB with the 52832. Not much ground plane (PCB area is 25x30 mm). What would be the general recommendation for a small chip...
Now we use the SDK V11 I2S sample program to collect data of digital microphone. We want to get the frequency of the sound and the dB value size.I don't know how to calculate...
Hi guys,
I want to know if it is possible to get started on developing applications for nRF51822 without using the evaluation kit. I want ot have a couple of breakout boards...
Hi,
I am testing that nRF52832 transfer QVGA still image from image sensor to phone as follows.
nRF52832(nRF52 DK) is connected with image sensor through some...
Hi All,
About DFU.
I want to know about UART DOWNLOAD for nRF51822 with S130.
Can I download the firmware via UART for nRF51822 with S130 ?
It's not OTA DFU.

I wanted to know what's the maximum data throughput if one device has both roles (Client/Server) working at the same time. I already saw the tables for the different SoftDevices...
Is there another IC I need to integrate into my board to allow the chip to be programmed through USB? Also, is the same true for programming OTA? I understand that I will...
Is there anyway to enable the UART on a NRF51822 to be 7-bit data instead of the default 8-bit?
Lowest level driver structure I could find is
NRF_UART_Type (nrf51.h...
I'm using Master Control Panel for PC to try to test bonding with MITM security on the peripheral I'm developing, and I suspect there's something wrong with the Master Emulator...
I am using the nRF52 in 2Mbps proprietary mode. I am running my own custom stack to maximize data throughput. There are no re-transmissions in my design. I have a loop of...
