This is driving me totally nuts. There are inconsistent pieces of information in documents and code. I am getting a modem reset loop problem. The documentation says the timer...
Hi,
Long story short, I made some boards using nrf9160 modules, received parts from DigiKey, soldered but can't make them work, at all.
nReset pin is stuck low. Tried...
I am using nRF52832 for high-rate sensor.
Of course, I can use SPI using CPU but it's busy for other jobs.
So I want to use DMA if it's possible.
Currently I am using...
