Hello, Would you have application that can support two nRF52840 pairing and transfer arbitrary large data files?
Our nRF51822, S110 device uses concurrent advertising (iBeacons) when connected to the central. Our customer would like to have a variable tx power on the advertising packets only. Is there any way we could do this?
So... As I understand it, micro-ECC is a free library that lets you create an ECC private key for signing the SecureDFU that Nordic is using.
The nrf52840 has Cryptocell 310 which has ECC hardware.
To the best of my ... (more)
