Hi,
When I'm trying the throughput on nRF52840 with SDK v14.2, I set up a 52840PDK as a 'repeater'; in which case the 'repeater' will receive the output (20kBytes in total...
which app should I use when I want to do LL BQB test with harmony on nRF52840?
it can not connected with harmony when I use DTM project. It seems the interface of nRF52840...
Dear nordic,
I am currently working with nRf52840. For designing antenna is there any role for dielectric layer thickness and conductive copper layer thickness
