Hi,
I have two CPU in our product. (STM32F2 and Nordic nrf51422).
I use serialization function to link those two CPU(refer to ble_s110_serialization sample)
But I find...

Hello,
after I could not use the nRF9160 DK I bought almost a year ago in Germany due to the missing nb-iot coverage I was very curious about the Thingy91 and I assumed...
Sorry for a noob questions but it is essential at this moment as I have not done any development on NordicSemi chips.
What software and hardware tools I need to develop...
