How to Delete Bonds with the Nordic nRF5 SDK

When we talk about Bluetooth-connected devices, an inherent part of that discussion is bond management. Bond management consists of storing and deleting information about a paired device so that the pairing process between two authenticated devices doesn’t need to be repeated on every connection.  When we use wireless headphones, for example, we don’t have to go through the set-up steps every time we want to connect to our phones.…

The 4 Key Benefits of Automated Testing

In many ways, I’m your stereotypical software engineer. I don’t do small talk, but I can talk for days about my work and side projects. I’m easily irked by inefficiencies -- if it can be done more efficiently, why not do it that way? I also…
