Some projects moved,and some another projects didn't move.
I...
I don't find the information in the nRF51822 documentations and in this forum.
How can I know that? Is there some register to check, or some hints to know that debug mode...
hi,
i am using the nrf51422 and trying the UART example ( in order to connect the nrf51422 and a stm32f4 using serial connection)
what i didn't understand is what does the...
I am using a nRF51822(pca10028) for current measurement. I had set up the devices as told in user guide. I am using SDK 11.0, softdevice s130 and default ble_app_pwr_profiling...
I am trying to make a custom BLE service and be able to do debug it with UART at the same time.
Just trying to print some UART messages at some points in the code.
However...
I have a couple of questions with the MCP.
Before knowing MCP, I've been connecting with my nrf51-DK with the nordic master control app installed in my smartphone. Opening...

Is there a way to avoid fees, and still use BLE? Do I need to change UUIDs or leave them be?
If not can the nrf51822 be used to just use the pure 2.4 ghz protocol and DFU...
If a BLE device using nRF51822 has a freuqency drift around 80kHz (BLE limit is 50kHz). All other measurement item like ICFT can pass the BLE spec. Will the performance of...
Hi, this is my very first post to this forum.
I just received my nRF51 DK, so I installed a lot of stuff. The blinky example is running fine.
A question about nRFgo Studio...
