Is there any...
Do u have mobile/ios application that allows you to scan for Bluetooth low energy devices with nRF52840 and communicate with them?
If not, how we can do it?
Hi,
I am wondering which is the best method for BLE security to avoid MITM, protect the data (sniffers) and limit connection only to allowed devices for a massive number...
