Mike Szczys

Mike is a Firmware Engineer at Golioth. His deep love of microcontrollers began in the early 2000s, growing from the desire to make more of the BEAM robotics he was building. During his 12 years at Hackaday (eight of them as Editor in Chief), he had a front-row seat for the growth of the industry, and was active in developing a number of custom electronic conference badges. When he's not reading data sheets he's busy as an orchestra musician in Madison, Wisconsin.

Enabling Bluetooth-to-Cloud on the STM32WB5MM-DK

Golioth makes it easy to connect Bluetooth devices to the cloud. Load provided binaries to create a Bluetooth gateway, then use reference Zephyr code to connect BLE devices from your fleet to the Internet. Here we show how to add an STMicroelectronics dev board as a leaf node in your fleet.

How to Sniff Cellular Packets with a Nordic nRF91

Sniffing network packets from a cellular modem is actually pretty easy. It only seems daunting because at first glance you're left wondering how to acquire the packets. Nordic's nRF91 modems have a trace capability that can be used to pipe packets from the device into Wireshark over a USB connection. Here's how to use it.

OTA: Working with Multiple Images

OTA usually makes people think of updating firmware. But OTA also covers many of other applications, like distributing new machine learning models, UI image assets, or firmware updates for other "downstream" processors. Golioth has the flexibility to support all these use cases. Here's how to use the power of the Golioth OTA service when you need to deploy more than just one binary.

Provisioning Devices over NFC

There are a hundred ways to provision a device, and with this NFC-based hack day project there are now 101. Follow along as we us a Nordic nRF53 as a writable NFC tag that parses the NDEF message, locates PSK-ID and PSK, then stores those credentials to add the device to an IoT fleet.

Use your J-Link Programmer as a Serial Port for your Device

If you're already using a J-Link programmer in your embedded development, you can use it to interface directly with the target device serial port over the J-Link USB connection. This is extremely handy, especially if your hardware design connects RX/TX pins to the programming header.
