Several users have pointed out a sudden flash size increase in some of our Bluetooth examples. We decided to write a quick post here to describe the reason for this and explain how to decrease the size of the examples.The reason for the size increase is that we added our logging module to the examples in question. Simply disable the module to decrease the size again.Logging can be turned on or off in sdk_config.h. This header file is included in all BLE examples. Remember that you can edit sdk_config usin...

The biggest pain point when debugging an application on the nRF51 series is the inability to set breakpoints while the SoftDevice is active without triggering an assert. Although a workaround exists that allows the debugging process to limp along for a short amount of time after the SoftDevice complains, using breakpoints with the nRF51 is inevitably a disruptive process.Thankfully, the nRF52 series includes support for a neat feature called Monitor Mode Debugging. When this feature is enabled, the proces...

Content of this blog based on the documentation of BLE Secure DFU example and Bootloader module library in our SDK. Here we provide you with step by step introduction to make it easier to follow and test Secure DFU.The Secure DFU is the new DFU bootloader provided from nRF 5 SDK v12. The old bootloader in SDKv11 and earlier is called Legacy DFU. Secure DFU is not backward compatible with Legacy DFU. What you would need to prepare before we start: Up to date nRF5 SDK (minimum SDK v12) Python with...

Hello,Would you have application that can support two nRF52840 pairing and transfer arbitrary large data files?Thanks,Gerry...

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 ability to check this, they are not using compatible curve profiles. Doesn't it make the most sense that one of the curve options used in the hardware reflects the curve options used for Nordic software?...
