New blog #rfid #hacking

When debugging LF RFID protocols on the #ChameleonUltra, you often need to answer a basic question: is the field actually doing what the firmware thinks it is? For reader-talk-first protocols like #EM4305, the entire exchange depends on gap-encoded commands being sent […]

So I spent some time optimizing the #MeshCore firmware to use less power on some companion devices.

Especially if you are using devices based on #nrf52840 like #T1000E or #WisMeshTag and want to avoid draining the battery when the device is powered off, you might want to look at […]

The last few days I spent a fair chunk of my day arguing with the nRF Connect SDK and its Partition Manager…

The goal: trying to get NSIB and mcuboot to behave with the secondary image on external (QSPI) flash.

Took the better part of yesterday and today just getting a `pm_static.yml` […]
