As a brief introduction, our research group uses bluetooth advertising to broadcast commands and responses between end devices and 'routers' which are connected to a PC. ...
Hi,
BLE Application on nRF52840 (pca10056) development board is being developed.
Application stopped the advertising to make device non-discoverable.
After that trying...
