With my Iphone I can discover this device and I am able to connect to it and listen to notifications of the...
Hi
The 840 datasheet (page 90) states that the HFINT tolerance is +/-1.5% typical and +/-8% max.
Under normal operation, the HFINT is running and so if the device (like...
I was beyond excited to see all the support Nordic was providing to the mbedOS project.
All of a sudden it disappeared.
If not supporting mbed the alternatives would...
Hello,
We have an nrf51822 system where disconnecting the battery is problematic, and the sharing of the reset line between SWD and reset function has been a real source...
Hi. I'm beginner of nRF.
I want to get some data from a temperature sensor, but I don't know how to assign a pin. Also, how can I check the data ??
In Arduino, there...
Hello,
I'm attempting to include the "arm_math.h" library so that I can use the requisite DSP functions, etc. I'm getting a linker error so I'm not sure what else needs...
HI,
