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'm using nrf51 without ble.
I want to update flash but not want to delete PAGE every time.
NRF_NVMC->ERASEPAGE = (uint32_t) page_address;
How can i do?
We use IOS DFU toolbox to upgrade firmware with BLE device. we can upgrade successfully with Android, but always failed with IOS.
wrong code is: DFUErrorReadingVersionFailed...
Hi, it's probably a very dumb question, but i don't seem to find any details about it. In nrf52 SDK documentation, in Error Module section it says
The behavior of the...

Hi,
I am using ble_app_uart sample code for testing. In that I want to store the incoming data into to three buffers and simultaneously sending this over BLE. i.e., consider...
hi i m using nrf52832 for detection acceleration , angular speed and detection of magetic field with GY-87 ( MPU 6050 and Hmc5883). in fact i wrote a program that read only...
Hi,
I am using s130v2 and running the example code from: nRF5_SDK_12.3.0_d7731ad\examples\ble_peripheral\ble_app_hrs\pca10028\s130\arm4
This is the only modification I...
Hi,
I know this is a Bluetooth 5 spec question, but wanted to know the practical figures for current consumption when nrf52840 is used as both central and peripheral...
Hi,
We are expecting many of our devices to be in close proximity. How can we be certain that when a user initiates a buttonless DFU, that they are uploading to the correct...
