Hello,
I am using the custom board.
There is 32MHz external oscillator.
So, I implemented like below source code for clock control.
NRF_CLOCK->LFCLKSRC = (CLOCK_HFCLKSTAT_SRC_Xtal...
Hey,
we encounter very strange behaviour when using encryption (without MITM) in conjunction with write without response . If characteristics are unencrypted (open), write...
With ShockBurst activated the PRX receives some of the packets at 7 to 8 meters, and the PTX only receives the ACK at 4 to 5 meters….
The explanation for this is that the...
I'm asking because I recently figured out my modules aren't based on revision 2 chips as expected but on revision 1.
Maybe someone already made some experiences on this...
I connected my SEEED Ble Micro module via SWD to my nRF51-DK.
I then pressed ERASE ALL in the nRFgo Studio.
It worked. Now my Module is kinda empty. How to get stuff...

Hi,
I searched here for a while and I couldn't find the answer. I implemented custom service by referencing nAN-36 and the github code. For some reasons, the github code...
Hi there,
I am trying to generate a pulse on a pin using RTC1 and PPI. Using a TIMER this works fine but my goal is to incur minimum current consumption by using only the...
I was trying to calculate analog voltage in nrf51822 through ADC.
I used analog 2 pin
ref voltage =1.2v
pre scaler = 1/3
so while i connected 0.9v to analog pin.
I see...
