There is the board mark on the chip like n51822CEAAD01350A0, where DO is Build code, 1350 is tracking code(YYMM), A0 is lot code.
My question is how can I get those codes...
I'm trying to debug a randomly occuring Hardfault. In trying to trace down the source I read the CPU registers use the Nordic hardfault_implementation.c which grabs the register...

Hi,
I am a bit confused about power consumption when using app_uart_fifo. To save power I put MCU to sleep in between each sent and received byte by using __WFE and __SEV...
I was redefining the init packet and when it came time to generate the nano-pb files, it looks like there is a fair amount of difference in the newly auto generated pb.c and...
Sorry if these questions are discussed already. I'm a newbie to Bluetooth project. Let me explain in brief. I have a central and peripheral device. I am transmitting 10samples...
After quite a few difficulties getting Keilv5 to work with the included examples with no responses ( devzone.nordicsemi.com/.../) I decided to give Eclipse a shot.

Good day All,
We are in the process off procuring a project using nRF52, and I need to find out some important things. Are there any costs in using any of the libraries...
I am using nrf52840 module(peripheral) for transmitting 10samples/10ms and central device as the same nrf52840 for receiving the samples. Although I receive the packets, there...
Hello,
I'm working on an application in which I have to dynamically switch between a TWI master peripheral and SPI master peripheral that use the same peripheral ID (our...

Hi,
i'm wondering if there is any IC (for example nRF52832) that can reach a range up to 155 meters available within the Nordic semiconductor catalog ?
i know that the...
In nRF5 SDK 12.1.0 a bug was fixed in nrf_drv_wdt_init(). Watchdog timeout could not be larger than 131 seconds because of (x * 32768) multiplication before. This bug is again...
In the spec it says that the typical ramp up time is 140us (or 40us in fast mode). But there is no details on maximum or minimum. What is the true tolerance on this value...
We are building a simple project, let 51822 connect the mobile, once per second. We found that the Tx power of 51822 is getting weaker and weaker (view the voltage over a...
I have a nrf51 dongle and would like to use PWM on 3 pins.
Managed to get it working on pins 15 and 16, but somehow pins from 17 to 20 just don't work.
For example: I set...
Hi,
