Dear support,
Our team is considered doing their own smart watch, so i found that nRF52 chip is a nice solution. Just before we start, i would like to do some basic questions...
When we ported our FreeRTOS based project to SDK 15.3 from 15.2, we noticed a big jump in the CPU Usage. It turned out that the issue was in SDK 15.3's freertos port_cmsis_systick...
Hi nordic,
I send multiple bytes but always only receive packets of length = 1. For example in the picture, I sent 2 bytes 0x68, 0x69 ('DE') but only received the first...
Hi
What is the difference between ble_nus.c and ble_nus_c.c?
because i went through both the files and i felt both files are almost same except an extra function(db_discovery...
Hello, I bought a nRF52832 Breakout Board from SparkFun. from their tutorial, you can program this board using the serial bootloader and the Arduino IDE. However, aside for...

After connecting the dk to nrf connect desktop and programming it with a wrong code (by mistake), it is not able to...
I'm using the nRF52840 DK.
I managed to burn the on-board nRF52840 MCU several times, using the nRF connect windows app.
After several such successful burns, with various...
Hi,
According to the datasheet:
Does this mean that when i change my vdd from 3V to 2V, then the current peaks will be reduced? If so what does this:
graph means...
