Hi,
My goal is to send raw frames to some external device which is not nRF BLE example but commercial used device.
It is using some fixed service with fixed UUID and I...
I doubt Nordic developed a brand new GPS receiver for the 9160. Where does it come from (manufacturer and model)?
The Thingy91 Asset Tracker out of the box example has some...
The Thingy:52 Environment Service uses this structure to represent Temperature.:
This is wrong - it cannot correctly represent temperatures below zero but above -1 ...
pls advise if nrf9160 DK can work in RDP protocol , say the board is in US to work on NBIOT carrier or LTEM carrier . Can it be configured in some way to do evaluation remotely...
Hello!
It seems to me that GCC compiler optimization (-O3 -g3) somehow break the SAADC.
When enabling said optimizations the SAADC no longer gives me valid measurements...
