In our earlier projects with nRF51 and SDK 8 we used to have bluetooth device names of length 13 or 14 characters. However, when using nRF52 and SDK 12 I noticed that the...
This should be simple, but I just can't get it working.
Many examples show setting a flag before calling the pstorage clear/store/load functions and then looping, waiting...
I use spi_slave with SDK 9.0.0. SPI slave is working, but there is some current leak when it become system off mode. I think the reason is that MISO is HI-Z at that time....
Hello,
